Summary

In 2011, the twelfth round of the Interlaboratory Com-parison on POPs in Food was conducted on the deter-mination of the 2,3,7,8-chlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) as well as dioxin-like non-ortho and mono-ortho chlorinated biphenyls (dl-PCBs) in three different food items. In addition laboratories could voluntarily determine and report six Indicator PCBs, polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD). The objectives of this interlaboratory comparison study were a) to offer a quality assurance instrument for the participating laboratories, b) to assess the between laboratory repro-ducibility and c) to assess the readiness of expert labora-tories world-wide to determine levels of chlorinated and brominated persistent organic pollutants in regular foodstuffs.

The 2011 study was performed on sample homo-genates of salmon filet, mozzarella cheese and eggs. In addition, six standard solutions were provided contain-ing known concentrations of 1) PCDDs/ PCDFs, 2) non-ortho PCBs, 3) mono-ortho PCBs, 4) PBDEs, 5) Indicator PCBs and 6) α-HBCD. The testing materials were sent to 103 laboratories in January 2011, and results were returned from 101 laboratories in 31 different countries by the deadline in April. Most laboratories analyzed all the three food items. A draft report was made available on the Internet in August and was discussed among the participants at the Waters New Technology Forum during the DIOXIN 2011 Symposium in Brussels, Belgium.

This report presents the submitted results for: all seventeen 2,3,7,8-substituted PCDDs/PCDFs, the non-ortho substituted PCBs #77, 81, 126 and 169 and the eight mono-ortho substituted PCBs #105, 114, 118, 123, 156, 157, 167, 189 in the three food items on a fresh weight and lipid weight basis. In addition, the results for eight PBDEs #28, 47, 99, 100, 153, 154, 183 and 209, six Indicator PCBs #28, 52, 101, 138, 153 and 180, and total HBCD as well as the α-, β- and γ-isomers were reported from those laboratories that voluntarily determined their concentrations. Non-detected congeners were assigned a concentration corresponding to the reported detection limit except for PBDEs, Indicator PCBs and HBCD where non-detects were removed from the data set. The consensus concentration (assigned value) for each analyte in the three food samples was determined as follows: The median of all reported concentrations for each analyte was calculated. All values above two times the median were removed from the calculation. The consensus median and consensus mean plus standard

deviation (SD) were calculated from the remaining data. Toxic equivalents (TEQs) were calculated from the con-sensus values of individual congeners using the toxic equivalency factors derived by WHO in 1998 and 2005. Z-scores for PCDD/PCDF TEQs were calculated for each laboratory using ± 20% of the consensus TEQs (WHO-1998TEQs) as a value for target standard deviation (σ). Further, Z-scores were calculated for the non-ortho PCB TEQ, the mono-ortho PCB TEQ, the total TEQ, the sum of six Indicator PCBs, the sum of eight PBDEs, total HBCD, and the three isomers of HBCD and for each single congener in all three matrices.

The consensus values for the standard solutions were calculated as mentioned above except that values outside ± 50% of the median of all values were removed prior to the final calculation of the consensus median and mean. The consensus values for the lipid content were calculated by first excluding results deviating more than two SD from the mean of all values and then re-calculating the median, mean and SD.

For the determination of total TEQs in the three food samples, Z-scores within ± 1 were obtained by 76-85% of the laboratories. The majority of the laboratories (88-90%) reported results for total TEQ with a trueness of ± 40% for all food samples (Z-score ± 2). The relative standard deviation (RSD) calculated for the total TEQ after removal of outliers was 11-13%. It is therefore con-cluded that the performance of laboratories world-wide in determining dioxin-like compounds is generally good for the food samples included in this study.

For the different food samples, between 55-68 labo-ratories reported results for the six Indicator PCBs, 31-41 laboratories reported concentrations for the seven tetra- to hepta-BDEs and 22-27 laboratories reported concentrations for BDE-209. The concentrations of the sum of seven PBDEs on fresh weight basis were 2130 (28%), 220 (33%) and 258 (31%) pg/g in salmon, Mozzarella and eggs, respectively, with average RSD given in parentheses. The consensus concentrations for BDE-209 were 42 (n=27), 28 (n=25) and 111 (n=22) pg/g fresh weight in salmon filet, Mozzarella cheese and eggs, respectively. The corresponding RSD on fresh weight basis were 48, 62 and 36%. The consensus concentrations calculated for HBCD are just indicative values as only few laboratories reported results. The sums of concentrations on fresh weight basis for six Indi-cator PCBs were 32.3 ng/g (26%) in salmon, 0.92 (37%) ng/g in Mozzarella cheese and 1.45 (33%) ng/g in eggs. Average RSDs are given in parentheses.

Introduction

In order to ensure consumer protection and reduce human exposure to dioxins and dioxin-like PCBs through food consumption, many countries request frequent monitoring of the presence of these toxic pollutants in food and feed. Thus, there is a large demand for chemical laboratories that are able to determine these contaminants at low levels in food and feed. It is usually required by the authorities that labora-tories performing such measurements are accredited according to ISO standards and prove their competence by successful participation in interlaboratory studies.

This study is the twelft round of a world-wide interlaboratory comparison study on halogeniated persistent organic pollutants in food organized by the Department of Analytical Chemistry, Division of Environmental Medicine, Norwegian Institute of Public Health, Oslo, Norway.

The exercise took place from January 2011, when the samples were shipped to the laboratories for analy-sis, to the reporting deadline in April 2011, when the last reports on the results were received. A draft report

was made available to the participants on the new webpage (http://www.fhi.no/ILC) in August and was discussed during the Waters New Technology Forum at the DIOXIN 2011 Symposium in Brussels, Belgium.

The main objective of this exercise was to assess the between laboratory reproducibility of dioxin-like compounds analyses in frequently consumed foods and provide a QA/QC instrument for each participating labo-ratory to contribute to its proficiency. Participants were also asked to voluntarily determine the concen trations of eight PBDEs, six Indicator PCBs and HBCD in the food samples in order to assess the readiness of laboratories to analyze these persistent organic pollutants .

All of the participants from previous rounds of this series of “Interlaboratory Comparisons on POPs in Food” were invited to participate. In addition, several other laboratories announced their participation. There was no limit to the total number of participat-ing labora tories. The 101 laboratories that submitted results, and thereby contributed to the study results, are presented in Table 1.

Study design and reporting of results

As in the previous rounds of this interlaboratory com-parison studies, the test material chosen represented naturally contaminated food samples. The analytes to be determined by each participating laboratory were all seventeen 2,3,7,8-substituted PCDDs/PCDFs, the four non-ortho substituted PCBs #77, 81, 126 and 169 and the eight mono-ortho substituted PCBs #105, 114, 118, 123, 156, 157, 167 and 189. In addition, labora-tories were asked to determine on a voluntary basis eight PBDEs #28, 47, 99, 100, 153, 154, 183 and 209, six Indicator PCBs #28, 52, 101, 138, 153 and 180, total HBCD and it’s three isomers (α-, β-, γ-HBCD). The six PCB congeners belong together with the mono-ortho PCB #118 to the selection of PCBs commonly referred to as ICES-7.

The analysis should be performed using the laboratories’ own methods for sample preparation and instrumental analysis, their own standards and quantification procedures and their own method for lipid determination.

It was recommended that laboratories determine as many as possible of the 2,3,7,8-substituted PCDDs/ PCDFs, dioxin-like PCBs, PBDEs, Indicator PCBs and HBCD. The report was to include the determined lipid percent for the test samples. Also the actual sample and lipid amount (g) for each determination should be reported. For each sample, laboratories were to report the found concentration on fresh weight basis for each congener which was detected (e.g. S/N ≥3) as well as the limit of determination (LOD, e.g., S/N =3). Non-de-tected congeners (e.g. S/N <3) were to be marked “ND” in the comments column of the Report form.

In addition, six standard solutions containing known concentrations of 1) seventeen 2,3,7,8-substi-tuted PCDDs/PCDFs, 2) four non-ortho PCBs, 3) eight mono-ortho PCBs, 4) eight PBDEs, 5) six Indicator PCBs and 6) α-HBCD were to be analyzed using the labora-tory’s own quantification standards and methods. The results were reported on separate forms.

The test materials consisted of salmon filet, mozzarella cheese and eggs. The laboratories could choose to analyze one, two or all three food samples.

Each participating laboratory was given a specific code by the co-coordinators. In the present report, the participants are presented in the tables and figures by

their laboratory codes. Participants had access to their own code only and laboratory codes were not revealed to third parties.

On receipt by the co-coordinators, the raw data from the laboratories were entered into a database. The draft final report was generated and made avail-able to all participants on the Internet in August 2011. The draft of the final report was discussed at the Waters users’ meeting at DIOXIN 2011 in August in Brussels, Belgium.

Collection, preparation, and distribution of samples

Samples shipped to the participants comprised one to three of the following:

• Salmonfilet:ObtainedfromtheBalticSea(115g)• Mozzarellacheese:ObtainedfromItaly(50g)• Egg:ObtainedfromTheNetherlands(70g)

The test materials consisted of three natural products not fortified with standards.

Homogenization of the salmon and mozzarella cheese was performed by repeatedly grinding portions of the food item in a grinder and homogenizing these portions in a mixer. The homogeneity of these materi-als was tested using an approach developed at NIPH. The rationale for and description of the test method is given in Appendix E. The egg sample was carefully warmed to 30ºC, filtered through gauze, thoroughly mixed by stirring and subsequently subdivided. Sub-samples of at least 115 g of salmon filet (S), 50 g of Mozzarella cheese (M) and 70 g of eggs (E) were placed into carefully cleaned screw-cap glass bottles. All sam-ples were stored at –20 °C until shipment. The frozen samples were shipped to the participating laboratories marked as test material S, M and E.

Statistical analysis

Based on experiences from previous rounds, we have chosen the following approach for the calculation of the consensus concentrations for each of the congeners:

10 Rapport 2011:7 • Folkehelseinstituttet

For PCDDs/PCDFs and dioxin-like PCBs congener-by-congener medians were calculated from the food sample data of all reporting laboratories using the detection limit as concentration for non-detected congeners (upperbound concentration). For PBDEs, In-dicator PCBs and HBCD, non-detected congeners were removed from the data set prior to consensus calcula-tion. Outliers were defined as those values above two times the median of all values and were removed from the data set. The consensus values were defined as the median of the remaining data for each congener. In addition, the consensus mean and SD were calculated from this data set for each congener. Those congener data which had been removed prior to consensus calculation are marked in the tables presenting the individual results.

For the standard solutions, outliers were defined as those values outside ± 50% of the median of all re-ported values. Consensus median, mean and SD were calculated from the remaining data. The consensus of the lipid content was calculated as the mean after removal of values outside ± 2SD.

TEQs were calculated from the consensus values for PCDDs/PCDFs, non-ortho PCBs, and mono-ortho PCBs, using the toxic equivalency factors derived by WHO in 1998 and 2005. As the detection limit was used for the concentration of non-detects, these TEQs represent upper bound concentrations.

Z-scores for PCDD/PCDF TEQ as well as for the non-ortho PCB TEQ, the mono-ortho PCB TEQ , the total TEQ (WHO1998TEQs) the sum of six Indicator PCBs, the sum of eight PBDEs, total HBCD and for each congener were calculated for each laboratory accord-ing to the following equation:

z = (x – X)/σ

Where x = reported value; X = consensus value (assigned value) ; σ = target value for standard devia-tion. A σ of 20% of the consensus was used, i.e. Z-scores between +1 and -1 reflect a deviation of ± 20% from the consensus value.

The final report and certificate

The draft of the final report was prepared by the co-coordinators and published on the web in August 2011. The draft was discussed at the Waters Users’ Meeting at the DIOXIN2011 Symposium in August in Brussels, Belgium.

A certificate, stating the participant’s code, will be sent to each participant contributing to the results at the end of 2011. The final report will be made available to the participants in pdf format at www.fhi.no/ILC.

The results are presented in the following chapters. A participating laboratory will be able to compare its performance congener by congener with the other laboratories. Since variations in performances are based on several factors, it is recommended that each laboratory carefully evaluates the factors that, favorably or unfavorably, have contributed to its performance. A general reader of the report, who has no access to the laboratory codes, will be able to get a picture of the analytical performance of laboratories world-wide for determining dioxins, dioxin-like PCBs, Indicator PCBs, PBDEs and HBCD in regular foods.

Presentation in the report

Results were submitted from 101 laboratories from 31 different countries. In Appendix C, the consensus statistics are given on fresh and lipid weight basis for concentrations and TEQ values of individual con-geners, a summary of TEQ values for each food item, and the Z-score plots based on a target deviation of ± 20%. Further, the results of the lipid determi-nations are presented. Finally, individual results reported by the laboratories for each congener are given for salmon filet, Mozzarella cheese and eggs in Appendix 2, 3 and 4.

Summarising comments on results

PCDDs/PCDFs

Analyte solution

Concentrations for PCDDs/PCDFs were reported by 86 laboratories. The average RSD for the 17 congeners was 9.3% ranging from 7.3% for 1,2,3,7,8-PeCDD to 12% for OCDF. The calculation of Z-scores for the TEQs (target 13.6 pg TEQ/μl) of the PCDD/PCDF standard solution showed that 95% of the labs were within the range of ± 20% of the consensus value. This demon-strates the high quality of the calibration solutions used by the laboratories.

Salmon filetFor the salmon filet sample, PCDD/PCDF results from 88 laboratories were received. The consensus TEQ was 8.1 pg TE/g fresh weight and 93 pg TE/g lipid. The average RSD was 34% ranging from 23-60%. Z-scores within ± 1 were obtained by 85% of the laboratories and 90% of the laboratories had Z-scores within ± 2. About 96% percent of the PCDD/PCDF TEQ is made up by the four congeners 2,3,7,8-TCDD, 1,2,3,7,8-PeCDD, 2,3,7,8-TCDF and 2,3,4,7,8-PeCDF.

Mozzarella cheesePCDD/PCDF concentrations in the Mozzarella cheese sample were reported by 73 laboratories. The consen-sus TEQ was 1.2 pg TE/g fresh weight and 4.3 pg TE/g lipid. The average RSD was 36% ranging from 23-70%. Z-scores were within ± 1 for 76% of the laboratories and within ± 2 for 88% of the laboratories. About 77% percent of the PCDD/PCDF TEQ is made up by the four congeners 2,3,7,8-TCDD, 1,2,3,7,8-PeCDD, 2,3,7,8-TCDF and 2,3,4,7,8-PeCDF.

EggsFor the egg sample, 74 laboratories determined PCDD/PCDF concentrations. The consensus TEQ was 0.76 pg/g fresh weight and 7.8 pg/g lipid. The average RSD was 30% ranging from 18-50%. Z-scores for PCDD/PCDF TEQ within ± 1 were obtained by 83% of the laboratories and 90% had Z-scores within ± 2. About 78% percent of the PCDD/PCDF TEQ is made up by the four congeners 2,3,7,8-TCDD, 1,2,3,7,8-PeCDD, 2,3,7,8-TCDF and 2,3,4,7,8-PeCDF.

Dioxin-like PCBs

Analyte solutionThe 12 dioxin-like PCBs in the analyte solution were analyzed and reported by 82 to 86 laboratories. The RSDs for the different congeners were 8.2-11% with an average of 9.3%.

Salmon filetDioxin-like PCB concentrations were reported from 86 to 90 laboratories. The concentrations of the 12 conge-ners varied between 2.2 pg/g fresh weight (CB-81) and 4816 pg/g fresh weight (CB-118). The dioxin-like PCBs contribute 62% to the total TEQ in the sample with CB-

126 as the main contributor (47%). The average RSD for concentrations of individual dioxin-like PCB congeners on fresh weight basis was 27% ranging from 22% for CB-105 to 48% for CB-123.

Mozzarella cheeseThe number of laboratories that measured and re-ported dioxin-like PCB concentrations in Mozzarella cheese were between 72 and 75. The concentrations ranged from 0.42 pg/g fresh weight for CB-81 to 222 pg/g fresh weight for CB-118. The dioxin-like PCBs contribute to about 29% of the total TEQ in the sample with CB-126 as the main contributor (29%). The aver-age RSD for concentrations of individual dioxin-like PCB congeners on fresh weight basis was 27% ranging from 21% for CB-153 to 50% for CB-77.

EggsDioxin-like PCBs were reported by 73 to 75 laboratories. Levels were ranging from 0.24 pg/g fresh weight for

CB-81 to 124 pg/g fresh weight for CB-118. The average RSD for concentrations of individual dioxin-like PCB congeners on fresh weight basis was 24% ranging from 19% for CB-189 to 35% for CB-123. The contribution of the dioxin-like PCBs to the total TEQ was about 54% with CB-126 as the main contributor (48%).

Total TEQ

In Figure 1 and 2 the contribution of the three groups of dioxin-like compounds is depicted based on WHO TEF1998 and WHO TEF2005, respectively. For salmon filet and eggs, dioxin-like PCBs contributed to 50% or more of the total TEQs (using WHO TEF1998), demon-strating the importance of PCBs for the determination of the total 2,3,7,8-TCDD related toxic potency of food samples.

The RSD for total TEQ on fresh weight basis calcu-lated from the RSD of individual congeners was 13% for salmon filet, 11% for Mozzarella cheese and 12% for eggs.

Indicator PCBs

Analyte solutionSixty-five laboratories reported Indicator PCBs in the analyte solution. The average RSD was 10% ranging form 9.5-11%.

Salmon filetFor the salmon filet sample Indicator PCB results were received from 68 laboratories. The concentrations were varying between 0.67 ng/g fresh weight (CB-28) and 12.1 ng/g fresh weight (CB-153). The RSDs were ranging from 21-32% with an average of 26%. The consensus median for the sum of Indicator PCBs was 32.3 ng/g fresh weight.

Mozzarella cheeseWithin the deadline, 55-56 laboratories reported results of Indicator PCBs in the Mozzarella cheese sample. The concentrations ranged form 22 pg/g fresh weight (CB-28) to 363 pg/g fresh weight (CB-153) with a consensus median for the sum of Indicator PCBs of 922 pg/g fresh weight. The average RSD was 37% ranging from 17-60%.

EggsResults were obtained from 56-57 laboratories. The concentrations of Indicator PCBs in the eggs sample were ranging from 6 pg/g fresh weight (CB-52) to 567 pg/g fresh weight (CB-153) and the consensus median for the sum was 241 pg/g fresh weight. The average RSD was 33% ranging from 17-59%.

PBDEs

Analyte solutionThe tri- to heptaBDE standard solution was analyzed by 41 to 42 laboratories and 29 laboratories reported values for BDE-209. The RSDs were between 8.1-11% for all congeners.

Salmon filetPBDE concentrations were reported by 40 to 41 labo-ratories, except for BDE-209 for which 27 results were received. The consensus concentrations were in the range 2.7 pg/g fresh weight for BDE-183 and 12.5 ng/g fresh weight for BDE-47. The consensus concentration for BDE-209 was 42 pg/g fresh weight. The sum of tri- to heptaBDEs was 21.3 ng/g fresh weight. The range of RSDs on fresh weight was 21-48% with an average of 31% including BDE-209.

Mozzarella cheese

Within the deadline, 34 laboratories had reported results for tri- to heptaBDEs and 25 laboratories reported results for BDE-209. The concentrations varied between 0.84 pg/g fresh weight (BDE-28) and 91 pg/g fresh weight (BDE-47/99). The concentration for BDE-209 was 28 pg/g fresh weight. The sum of tri- to heptaBDEs was 220 pg/g fresh weight. The RSD calculated from the concentrations on fresh weight ranged from 19-67% with an average of 36% for PBDEs including BDE-209.

EggsBetween 31 and 32 laboratories reported results for tri- to heptaBDEs and 22 reported results for BDE-209. The concentrations varied between 0.54 pg/g fresh weight (BDE-28) and 145 pg/g fresh weight (BDE-183). The concentration for BDE-209 was 111 pg/g fresh weight. The sum of tri- to heptaBDEs was 258 pg/g fresh weight. The RSDs for the individual congeners were ranging from 19 to 65% with an average of 32% including BDE-209.

HBCD

Also in this round of the study, total HBCD and the isomers α-, β- and γ-HBCD could be determined and reported. A total of 15 laboratories reported α-HBCD in the standard solution and 12-15 laboratories reported all three isomers in the food samples. The consen-sus concentrations for the sum of individual HBCD isomers were 2.1 ng/g fresh weight for salmon, and 151 and 111 pg/g fresh weight for Mozzarella cheese and eggs, respectively. Since only few laboratories reported HBCD, these values are regarded as indi cative. For salmon , the sum of individual isomers deter-mined by LC-MS agreed well with the total amount of HBCD determined by GC-MS. α-HBCD was the dominating (94%) isomer in this sample. For the other food samples , the discrepancy between the sum of individual isomers and the total HBCD was quite large.

Lipid content

The mean and RSDs (in parentheses) for the lipid contents of the food samples were calculated to be 8.6% (14%) for salmon filet, 26.7% (6%) for Mozzarella cheese and 9.8% (11%) for eggs.

Announcement for

Interlaboratory Comparison on POPs in Food 2011

Introduction

We herby announce the 12th round of the interlaboratory comparison on the determination of

dioxins, PCBs, PBDEs and HBCD in food. The study is open for academic, regulatory as well

as commercial laboratories world-wide. The organizer of this study is the Department of

Analytical Chemistry at the Norwegian Institute of Public Health in Oslo, Norway. The study

is scheduled to take place from January to April 2011. A draft report will be available prior to

the evaluation meeting which will take place at the Dioxin 2011 Symposium in August,

Brussels, Belgium. The final report will be available to the participants by December 2011

together with a certificate for participation.

Objectives

The objectives of this exercise are to assess the interlaboratory consistency in results from

analyses of dioxins, PCBs, PBDEs and HBCD in regular foods known to contribute to the

intake in the general population and to assess the world-wide readiness and capacity in

analysing dioxins and other halogenated persistent pollutants in food. The study also serves as

a quality assurance instrument for the participating laboratories.

Participants

We encourage all laboratories world-wide working in this field to participate and assess their

analytical performance. Participants are requested to completely fill out the Registration Form

and mark for the desired sample types and what analytes they intend to determine.

Analytical requirements

In this interlaboratory comparison, all the seventeen 2, 3, 7, 8-substituted PCDDs and PCDFs,

the four non-ortho PCBs, CB-77, 81, 126 and 169 as well as the eight mono-ortho PCBs, CB-

105, 114, 118, 123, 156, 157, 167, and 189 will be assessed. In addition, you are invited to

determine six marker PCBs, eight PBDEs and HBCD. The concentration of the following

congeners can be reported: CB-28, 52, 101, 138, 153 and 180 and BDE-28, 47, 99, 100, 153,

154, 183 and 209. The concentration of α-HBCD, β-HBCD and γ-HBCD as well as the total

of these isomers will also be assessed. The test materials consist of three fresh food

homogenates. You can choose to analyse one, two or all three of the food items. We

encourage you to determine as many analytes as possible. You are further requested to

determine and report the lipid content of the foods.

We also include standard solutions of all analytes that should be analysed as solutions of

known concentration, which may be used to check your own calibration solutions.

Test material

The test materials consist of three unfortified natural food product homogenates, Salmon filet

(labelled S) ~115 g, Mozzarella cheese (labelled M) ~50 g, and Eggs (labelled E) ~70 g, and

will be distributed by an international courier service to the participating laboratories.

In order to avoid delay at customs, please inform us if there are import restrictions for

any of these samples in your country.

Instructions for analysis and reporting

Further detailed instructions and reporting forms will be sent out simultaneously with the

dispatch of the samples in January.

In short, laboratories should:

• use their own standard operation procedures for extraction clean-up and instrumental

determination

• use their own reference standards for identification and quantification

• report a single concentration for each analyte in each food matrix determined on fresh

weight basis

• report limits of detection for all measured analytes in each food item

• report the lipid content

1. Introduction

This is the 12th round of the interlaboratory comparison exercise on the determination of

dioxins, PCBs, PBDEs and HBCD in food organised by the Department of Analytical

Chemistry, Norwegian Institute of Public Health, Oslo, Norway. The objective of this

exercise is to assess the interlaboratory comparability of the results from analyses of all

dioxins and dioxin-like PCBs included in the WHO98-TEF scheme in regular foods.

Participants may also determine and report concentrations of six marker PCBs, eight

polybrominated diphenylethers (PBDEs) and hexabromocyclododecane (HBCD). The

exercise serves as a quality assurance instrument for the participating laboratories. A further

objective is to assess the world-wide readiness and capacity for the determination of dioxin-

like compounds, marker PCBs, PBDEs and HBCD in food. Instructions for the analysis and

submission of results are given below.

Please read these instructions carefully before starting the experimental work.

The participating laboratories will collaboratively assess the interlaboratory comparability in

the analytical performance for determination of:

• dioxins and furans: all seventeen 2,3,7,8-substituted PCDDs and PCDFs

• non-ortho PCBs: CB-77, 81, 126 and 169

• mono-ortho PCBs: CB-105, 114, 118, 123, 156, 157, 167 and 189.

• marker PCBs: CB-28, 52, 101, 138, 153 and 180

• PBDEs: BDE-28, 47, 99, 100, 153, 154, 183 and 209

• HBCD α-HBCD, β-HBCD, γ-HBCD and total HBCD

In Eggs (E), Mozzarella Cheese (M), and Salmon (S).The mentioned analytes should also be

determined in the respective six standard solutions.

In this round of the Interlaboratory comparison study, the concentration of α-HBCD, β-HBCD

and γ-HBCD as well as the total of these isomers will be assessed. Both results from GC-MS

and LC-MS or LC-MS/MS are welcome.

One sample of each

• ca. 70 g eggs, lipid content about 10%

• ca. 50 g mozzarella cheese, lipid content about 20%

• ca. 115 g salmon, lipid content about 10%

Fortification

The samples are prepared from regular market foods. There is no fortification or spiking of

the PCDD, PCDF, PCB, PBDE or HBCD analytes in the food samples.

Shipment

The samples are fresh frozen food homogenates. They are distributed by DHL and should

reach the receiving laboratory in good condition within a few days. The airwaybill numbers

will be made available for the participants to trace the shipment at http://www.dhl.com.

3.2 Coding

Coding of laboratories

Upon arrival of the samples in the participant’s laboratory, the Microsoft excel file named

"Participant confirmation", shall be filled in and immediately returned to the co-ordinators by

e-mail or telefax. The code of the laboratory will then be given by the co-ordinators. The

laboratory codes will not be revealed to the other participants or to third parties.

Coding of samples

Egg samples E

Mozzarella samples M

Salmon samples S

The above sample coding is marked on the sample bottles.

3.3 Analytical procedure

Methods to be used

Laboratories shall use

• their own methods for sample preparation and instrumental analysis

• their own internal- and quantification standards

• their own lipid determination procedure

Page 34: rapport 2011:7 - Folkehelseinstituttet€¦ · 4 Rapport 2011:7 • Folkehelseinstituttet Summary In 2011, the twelfth round of the Interlaboratory Com-parison on POPs in Food was

Interlaboratory Comparison on Dioxins in Food 2011

Standard solutions

The standard solutions should be analysed using the laboratory’s own quantification standards

and methods and the results shall be reported.

General

Beware of the high risk of background contamination and positive blank values when

analysing food samples with levels of dioxins, PCBs, PBDEs and HBCD in the low ppt range.

Use sample size according to expected levels of dioxins for the determinations in order to

achieve a detection level that leaves as few as possible analytes as non-detected. The sample

amount dispatched is not meant for replicate analyses.

The samples might become inhomogeneous during freezing and transport. Re-homogenise all

received material of each food item before any portion is taken out for analysis.

4. Reporting

4.1 Results to be reported

Laboratories are recommended to report as many as possible of the congeners mentioned in

chapter 1.

The reports must include the determined lipid percent for all three matrixes. Also, the actual

sample amount (g) for each determination must be reported.

The analytical report must include concentrations for all the congeners in all the samples on

fresh weight basis, see Report forms B, C, D for PCDD/PCDF and dioxin-like PCBs and

Report form 2, 3, 4 for marker PCBs, PBDEs and HBCD.

Laboratories must report one concentration on fresh weight basis for each congener which is

detected (S/N ≥3), as well as the limit of determination (LOD, S/N =3) for each sample. Non-

detected congeners (S/N <3) must be marked ND in the Comments column of the Report

form. Please note that the LOD will be used as concentration of non-detected congeners.

4.2 Checklist

Please use the attached checklist before returning the Report forms with your results.

4.3 Submitting results

Three Microsoft Excel files are provided to each participant comprising:

Participants confirmation

• confirmation of receiving test materials

Report form dioxins and dioxinlike PCBs

Deadline

The reports must be in our hands no later than April 15th, 2011 to enable us to prepare

the draft report for the Dioxin 2011 Symposium in Brussels, Belgium. There will be no

extension of this deadline. A confirmation for receiving your results will be sent to you by e-

mail within a week.

5. Statistical evaluations

Prior to the final report, a draft version will be prepared based on the data reported by April

16th. The co-ordinators will calculate mean, median and between-laboratory standard

deviations for each congener. Outliers will be removed, and consensus values will be

calculated. In case of extreme deviation from normal distribution, appropriate procedures will

be used to get a best available estimate of the true value. For the dioxin-like compounds, TEQ

values will be calculated for each laboratory and a consensus TEQ value based on the

consensus of the congeners. Z-scores will be calculated for laboratories’ results for

PCDD/PCDF TEQs and PCB TEQs.

Statistical results based on the reported data as well as other important information from the

evaluation of the data, will be discussed during a consultation meeting in August at the Dioxin

2011 Symposium in Brussels, Belgium.

6. Final report

The final report will be prepared by the co-ordinators. All participants will be presented by

their laboratory code. A draft will be published on the Internet in July/August. The results will

be discussed during the Dioxin 2011 Symposium in Brussels, Belgium. The final report will

be available by November 2011. The report will be available in an electronic version on

http://www.fhi.no. Certificates of participation in the study will be given to all laboratories

submitting results.

Presentation of results for lipid determination

Removal of outliers and calculation of consensus were done by the following procedure:

1. The mean was calculated from all the reported data.

2. Values outside a range of ± 2 × the standard deviation of this mean, were defined as

outliers and removed from the data set.

3. Mean, standard deviation and median were re-calculated from the remaining data. This

mean was called consensus.

The diagram shows the reported data with consensus and consensus ± the new standard

deviation × 2.

Z-Scores of lipid content

Z-scores of lipid content were calculated for each laboratory according to the following

equation:

z = (x – X)/σ

Where x = reported value; X = assigned value (consensus); σ = target value for standard

deviation. A σ of 20% of the consensus was used, i.e. z-scores between +1 and -1 reflect a

deviation of ± 20% from the consensus value.

Homogeneity testing of test materials for “Interlaboratory Comparison on

Dioxins in Food” organised by the Norwegian Institute of Public Health

Introduction

The International Harmonized Protocol for the Proficiency Testing of Analytical Chemistry

Laboratories (Pure Appl Chem 2006;78:145-96) states that “The bulk material prepared for

the proficiency test must be sufficient homogeneous and stable, in respect of each analyte, to

ensure that all laboratories receive distribution units that do not differ to any consequential

degree in mean analyte concentration. The scheme provider must clearly state the procedure

used to establish the homogeneity of the test material”.

The protocol requires that the variation in composition among the distributed units is

negligible in relation to variation introduced by the measurements conducted by the

participants of the proficiency test (PT). The estimated variation between the samples (ssam)

should be less than 30% of the target standard deviation (σp), i.e., ssam < 0.3 σp.

Further the protocol states that homogeneity testing is required to reassure the participants in

proficiency testing schemes that the distributed units of the test material are sufficiently

similar. The test specified calls for the selection of ten or more units at random after the

putative homogenized material has been split and packaged into discrete samples for

distribution. The material from each sample is then analyzed in duplicate, under randomized

repeatability conditions (that is, all in one run) using a method with sufficient analytical

precision. The value of σsam is then estimated from the mean squares after one-way analysis of

variance (ANOVA).

Much depends on the quality of the analytical results of the homogeneity testing. If the

analytical precision (σan) of the homogeneity test is not small, important sampling variation

may be obscured by analytical variation. We may get a non-significant result when testing for

heterogeneity, not because it is not present, but the test has no power to detect it. It is

recommended that the analytical (repeatability) precision of the method used in the

homogeneity test should satisfy σan < 0.5 σp

Consequences for the Interlaboratory Comparison on Dioxins in Food

Below follows the consequences for the Interlaboratory Comparison on Dioxin in Food;

1.

The protocol recommends duplicate analysis of at least 10 distribution units. Due to limited

amount of test material in each distribution unit and the requirement for sufficiently low

analytical standard deviation, the test analysis has to be restricted to PCB, e.g., 6 indicator

PCB or CB-153. It is, however, questionable whether analysis of indicator PCB also reflects

the distribution of dioxins and other contaminants in the sample, as the test material is often

prepared by mixing specifically contaminated material with background contaminated

material in order to achieve a sufficient contamination level. Therefore, the distribution of

PCBs in the sample might not be relevant for the distribution of dioxins in the sample.

The analytical precision of the method used in the homogeneity test should be less than half

of the target standard deviation, i.e., σan < 0.5 σp. For determination of dioxins, the target

standard deviation may be approximated by the requirement for trueness (Commission

Regulation (EC) No 1883/2006) of ± 20% for total TEQ, i.e., the analytical precision should

be less than 10%. This is unrealistic to achieve for the determination of dioxins.

2.

The homogeneity testing using, e.g., the determination of indicator PCBs, requires the

analysis of at least 60 samples prior to shipment of the distribution units to the participants.

This causes problems for the time schedule of the sample preparation and involves high costs.

3.

The laboratory conducting the homogeneity test on PT analytes would have access to the test

material and knowledge of contamination levels prior to the start of the PT and would

therefore not be qualified for participation in the PT.

Conclusion

A valid testing of homogeneity of the test materials of the Interlaboratory Comparison (ILC)

on Dioxins in Food with respect to the distribution of dioxins and dioxin-like PCBs is not

guaranteed using indicator PCBs. It is doubtful that the analytical precision is small enough to

detect a lack in sufficient homogeneity. Given the need for annually testing three different

matrices for homogeneity, alternative, rapid and low cost homogeneity tests using surrogate

should be applied.

Present approach for homogeneity testing for the ILC on Dioxins in Food The Harmonized Protocol states under Chapter Testing for sufficient homogeneity: “Tests for

sufficient homogeneity are in practice never wholly satisfactory… However, given that

sufficient homogeneity is a reasonable prior assumption (because proficiency testing scheme

providers do their best to ensure it), and that the cost [and time-consumption] of testing for it

is often high, it is sensible to make the main emphasis the avoidance of “Type 1 errors” (that

is, false rejection of a satisfactory material).

Having this in mind and the facts that it is impossible to determine all analytes for

homogeneity testing of food test material and that a single indicator analyte not necessarily

reflects the distribution of the other analytes, we have developed an approach that ensures that

the test material is thoroughly blended and evenly distributed among the individual test

bottles. The homogeneity testing of solid samples is based on the principle of measuring

electrolytic conductivity after addition of sodium chloride to a small portion of the coarsely

blended test material. A demonstration of homogeneous distribution of the added salt in the

sub samples would indicate our ability to evenly blend the food matrix, i.e., with this

approach we ensure the efficiency of our blending procedure. This is especially of importance

when blending highly contaminated food matrices with background contaminated food

matrices.

When testing homogeneity of the food samples, sodium chloride was added to about 10% of

the test material in such an amount that the conductivity was about doubled compared to the

natural conductivity. This sub-sample was added to the total sample. For example, to 1 kg of

homogenised chicken meat, 150 g NaCl were added resulting in an addition of 1% NaCl to

the final test material of 15 kg. Conductivity measurements are performed as follows: boiling

water is added to 10.0g of the test material, and the resulting dispersion is ultrasonicated.

After centrifugation, the extract is filtered through folded paper filters and allowed to cool to

room temperature. The electrolytic conductivity of the water extract is measured using a

conductivity meter.

Homogeneity of the test material was demonstrated by comparing the conductivity in water

extracts of 10 samples from the same bottle (variation within bottles), and in extracts from 10

different bottles (variation between bottles).

Example

As an example, the relative standard deviation (RSD) of 10 conductivity measurements within

a sample bottle containing chicken meat homogenate was 2%. The RSD for the measurement

of samples from 10 different, randomly selected bottles was 3%. The contribution of the

inhomogeneity to the total variation, calculated from RSD2inhomogeneity = RSD

2between –

RSD2

within1 was 2.2% and hence small and acceptable. The total uncertainty for the

determination of PCDD/Fs is usually considerably larger, so the measured contribution of

inhomogeneity to the total uncertainty can be neglected

Appendix 1: Presentation of results: Analyte solution Statistic calculations for PCDDs, PCDFs, dioxin-like PCBs, indicator PCBs, PBDEs and α-HBCD

The analyte solution contained

� PCDDs/PCDFs at concentrations of 2:5:10 pg/µl for tetra:penta-hexa-hepta:octa

chlorinated dibenzodioxins/furans respectively.

� Non-ortho PCBs at concentration of 10 pg/µl.

� Mono-ortho PCBs and indicator PCBs at concentration of 100 pg/µl.

� PBDE at a concentration of 25 pg/µl, except BDE-209 at 100 pg/µl.

� α-HBCD at a concentration of 500 pg/µl.

These concentrations are called the congeners' target value.

For each congener, the outliers were removed and the consensus calculated according to the

following procedure:

1. The median was calculated from all the reported data.

2. Values outside a range of 50 % to 150 % of this median, were defined as outliers and

removed from the data set.

3. Median, mean and standard deviation were re-calculated from the remaining data. This

median and mean were called consensus median and mean.

The diagram shows the target value and the reported data. Values outside a range of 50 % to

150 % of “median of all values”, were defined as outliers and are not shown in the plot.

Z-Scores of individual congeners

Z-scores of each congener were calculated for each laboratory according to the following

equation:

z = (x – X)/σσσσ

Where x = reported value; X = assigned value (consensus); σ = target value for standard

deviation. A σ of 20% of the consensus was used, i.e. z-scores between +1 and -1 reflect a

deviation of ± 20% from the consensus value.

Statistic calculations for PCDDs, PCDFs and dioxin-like PCBs

For each congener, the outliers were removed and the consensus calculated according to the

following procedure:

1. The median was calculated from all the reported data, using the detection limit as

concentration for non-detected congeners.

2. Values exceeding 2 × this median, were defined as outliers and removed from the data set.

3. Median, mean and standard deviation were re-calculated from the remaining data. This

second median was called consensus.

Statistic calculations for indicator PCBs, PBDEs and HBCD

For each congener, the outliers were removed and the consensus calculated according to the

following procedure:

1. The median was calculated from all the reported data, using the detection limit as

concentration for non-detected congeners (NDs).

2. Values exceeding 2 × this median, were defined as outliers and removed from the data set.

The NDs were also removed.

3. Median, mean and standard deviation were re-calculated from the remaining data. This

second median was called consensus.

4. For comparison, median, mean and standard deviation were also calculated without

removing NDs.

The diagram shows the reported data up to approximately the limit for outliers (2 × the first

median).

Z-Scores of individual congeners

Z-scores of each congener were calculated for each laboratory according to the following

equation:

z = (x – X)/σ

where x = reported value; X = assigned value (consensus); σ = target value for standard

deviation. A σ of 20% of the consensus was used, i.e. z-scores between +1 and -1 reflect a

deviation of ± 20% from the consensus value.

Statistic calculations for PCDDs, PCDFs and dioxin-like PCBs

For each congener, the outliers were removed and the consensus calculated according to the

following procedure:

1. The median was calculated from all the reported data, using the detection limit as

concentration for non-detected congeners.

2. Values exceeding 2 × this median, were defined as outliers and removed from the data set.

3. Median, mean and standard deviation were re-calculated from the remaining data. This

second median was called consensus.

Statistic calculations for indicator PCBs, PBDEs and HBCD

For each congener, the outliers were removed and the consensus calculated according to the

following procedure:

1. The median was calculated from all the reported data, using the detection limit as

concentration for non-detected congeners (NDs).

2. Values exceeding 2 × this median, were defined as outliers and removed from the data set.

The NDs were also removed.

3. Median, mean and standard deviation were re-calculated from the remaining data. This

second median was called consensus.

4. For comparison, median, mean and standard deviation were also calculated without

removing NDs.

The diagram shows the reported data up to approximately the limit for outliers (2 × the first

median).

Z-Scores of individual congeners

Z-scores of each congener were calculated for each laboratory according to the following

equation:

z = (x – X)/σ

where x = reported value; X = assigned value (consensus); σ = target value for standard

deviation. A σ of 20% of the consensus was used, i.e. z-scores between +1 and -1 reflect a

deviation of ± 20% from the consensus value.

Statistic calculations for PCDDs, PCDFs and dioxin-like PCBs

For each congener, the outliers were removed and the consensus calculated according to the

following procedure:

1. The median was calculated from all the reported data, using the detection limit as

concentration for non-detected congeners.

2. Values exceeding 2 × this median, were defined as outliers and removed from the data set.

3. Median, mean and standard deviation were re-calculated from the remaining data. This

second median was called consensus.

Statistic calculations for indicator PCBs, PBDEs and HBCD

For each congener, the outliers were removed and the consensus calculated according to the

following procedure:

1. The median was calculated from all the reported data, using the detection limit as

concentration for non-detected congeners (NDs).

2. Values exceeding 2 × this median, were defined as outliers and removed from the data set.

The NDs were also removed.

3. Median, mean and standard deviation were re-calculated from the remaining data. This

second median was called consensus.

4. For comparison, median, mean and standard deviation were also calculated without

removing NDs.

The diagram shows the reported data up to approximately the limit for outliers (2 × the first

median).

Z-Scores of individual congeners

Z-scores of each congener were calculated for each laboratory according to the following

equation:

z = (x – X)/σ

where x = reported value; X = assigned value (consensus); σ = target value for standard

deviation. A σ of 20% of the consensus was used, i.e. z-scores between +1 and -1 reflect a

deviation of ± 20% from the consensus value.
