Certification of reference materials for the analysis of polychlorinated biphenyls - PCB, PAHs, PCP in industrially polluted soil


Industrial processes use hazardous substances and produce a large amount of waste that can harm human health and environment. Hazardous substances such as PCBs, PAHs or PCP (pentachlorophenol), have consequently been released into the environment contaminating air, waters and soils. Nowadays, many sites are contaminated because of uncontrolled dumps of former industrial plants, or due to industrial accidents. Rehabilitation of these polluted areas requires analytical characterization of priority pollutants. It is therefore necessary to have available validation tools to check the reliability of the determination of the contamination levels in the soils. One of the tools needed to validate the analytical measurements are properly certified reference materials for priority polluants (PCBs, PAHs and PCP).

The main objective of the present project is to certify two reference materials for PCBs, PAHs and PCP in two industrially polluted soils already prepared and stabilised. The main tasks are:

- designing the intercomparison exercises (methodology and strategy),
- organizing the administrative and technical management of these exercises,
- collecting and analyzing the intercomparison results,
- organizing a meeting to evaluate the technical validity of the certification of the reference material,
- inalizing the certification reports,
- publishing the certification work in a scientific journal.

The PCB material will be certified by the end of 1994. The PAH/PCP material will be certified in 1995.
