Belgian Dioxin crisis in 1999

• Problem : huge contamination of the Belgian human food chain by dioxins (PCDD/PCDF)

• Reason : reuse of contaminated waste animal fat in the animal food chain (feed of pigs and chickens)

• Threat to human health and enormous economic damage • VITO was established immediately by the Belgian

government as the reference lab to organise and perform the control analyses

• Development of new fast screening methods (CALUX) • Development of a food chain model to assess consumer

exposure and effects to public health

• Measurement of the environment in the surrounding• Use of dispersion models• measurements : on the company personel aiming at

assessing the exposure • measurements arround the company: via different exposure

pathways: hovering particles – deposited particules – inside and outside

• exposure modelling on the basis of the performed measurements

Turbidity measurements• Point measurements are expensive

• difficult to install in some locations

• The number of points is always limited

• the extent of the area for which measurements are relevant is often unknown

End-users are local, regional, national and international authorities

• Flemish fire brigades, municipalities• Antwerp harbour, private industry• Belgian Federal Police and Civil Protection• French and Dutch fire brigades (OSIRIS,

Miramap)• China• African partners (GMFS, AIDA)• …

The “perfect” sensor system do not exist

• Only combination of systems provides adequate information, especially for real-time issues

• Interoperability is therefore a key issue

• Selection of information is crucial (avoid data overflow)

• Understanding the end-user needs is not always obvious but is crucial• The end-users are following the technology developments and are mostly

open to innovative trials but theuy mostly trust much more a person than a machine

• During demos, the proposed solution should enhance the performances but not disturb the operationnal system

Some trends are

• Standardization (e.g. OGC for geographic information)• Development of smart sensors• Direct involvment of the population• Miniaturization and cost lowering• Development of sensor networks/constellations• Higher resolution => more data• Data fusion (all type) will increase• Processing will be more and more automated• Data processing in limited specialized centres

-> communication is very important• Concerning RS, UAV’s will play a major role during the next

decade
