TOXIC SUBSTANCES IN OUR EVERY-DAY LIFE

TOXIC SUBSTANCES IN OUR EVERY-DAY LIFE

• Chemicals – where do they come from?

• Effect on humans

• The PCB-story has restarted

THE BEDROCK IS THE SOURCE FOR METALS, OIL AND GAS

MORE THAN 100 000 CHEMICAL SUBSTANCES ARE NOW IN USE IN DIFFERENT PRODUCTS

BASED ON NATURAL RAWMATERIALS THE INDUSTRY HAS DEVELOPED NEW CHEMICALS

CHEMICALS IN TEXSTILES

• Antibacterial agents

• Anti-mould agents

• Dyes

• Flame retardents

• Softeners

• Impregnation agents

• Anti-fouling biocides

Triclosan, nano-silver Dimethylforamide Azo-dyes Brominated flame retardents Phtataltes Perflurcompounds Organotin compounds

SOFTENERS IN TOYS

Some pftalates in have ”hormone-like” properties

SUBSTANCES IN PLASTIC

BISPHENOL A ANTIMON

Cosmetics may contain triclosan, methylparabenes and siloxsan

ANTIBACTERIAL AGENTS

FLAME RETARDENTS

Brominated flame retardents PCB

PFOS

PCB´s

FOOD AND DRINKING WATER ARE THE MAIN SOURCES FOR HARMFUL SUBSTANCES FOR HUMANS

PCB-molekyl

17β-Østrogen

Thyroksin

• PCB

• Bisfenol A

• Ftalater

• DDT

• Parabener

• Nonylphenol

Some substances have hormone like properties

SAMPLES OF BLOOD ARE USED TO INDICATE THE BODY BURDEN OF TOXIC SUBTANCES

More than 20 toxic chemicals in my body

MINAMATA BAY IN JAPAN – CHISSO CORPORATION

WASTE WATER CONTAINING METHYL-MERCURY WERE SEND INTO THE MINAMATA BAYBAY

CHEMICAL POISONING

• Release of methyl mercury in the industrial waste water from Chissco Corperation's chemical factory

• 1784 people died and 9 000 were invalidisert's

BHOPAL- DISASTER IN 1984

A cloud of methyl isocyanate gas leaked fromtheUnion Carbide pesticide plant

BHOPAL- DISASTER IN 1984

Up to10 000 in the first three days

Additional 25 000 died of related injuries by 1994

What is the cocktail effect?

Some medical researchers have observed reduced male fertility during the last 30 years

TOXIC SUBSTANCES IN OUR EVERY-DAY LIFE

• Chemicals – where do they come from?

• Effect on humans

• The PCB-story has restarted

POLYCHLORINATED BIPHENYLS (PCB)

• Production started in 1929

• No production in Norway

• 1100 tons imported as additive to transformer - and capasitors oil - paint, windows, sealants, plaster, concrete and plastics

SØREN JENSEN – UNIVERSITY OF STOCKHOLM Detected PCBs in the the evironment in 1966

PCB CONGENER PROFILE IN CHICAGO -2010

PCBs, in order of increasing number of chlorines

PCB11

NO PCB 11 IN COMMERCIAL ARACLORS

Commercial Aroclors

PCB IN ORGANIC PIGMENTS

ORGANIC PIGMENTS (PCBS DETECTED)

• Norwegian paints contain azo- and ftalocyanin pigments produced by CPS Color in Finland

• Mono PCB: 2,05 mg/kg

• Di PCB: 3,7 mg/kg

• The total PCB containt is not known

PIGMENTS CONTAINING PCB ARE USED IN OTHER PRODUCTS

MODERN PRODUCTION OF PCB

• PCBs are produced as byproducts during the production of commonly used organic pigments.

• Their presence in common consumer products may dominate current sources to the environment

SUMMING UP

• More than 100 000 chemical substances are now in use in different products

• The effects on humanalth is not welknown for many ofthe substances, espesial for cocktail of substances

• PCBs are produced as byproducts during the production of commonly used organic pigments
