Project Details:

Collaborative study on novel and conventional extraction procedures for the determination of toxicologically relevant PCB congeners in fish

Project No.:	650-90-97
Start date:	1997-01-01
End date:	2001-12-31
Division:	Chemistry and the Environment Division

Expert laboratories (15-25) will collaboratively assess the comparability of novel extraction techniques such as super critical fluid extraction (SFE), microwave assisted solvent extraction techniques, and accelerated extraction with conventional solvent extraction techniques in the determination of selected polychlorinated biphenyls (PCBs) in fish. Emphasis will be on the identification and quantification of PCBs considered relevant for exposure and risk assessments, and on identifying and resolving problems in the routine application of novel extraction techniques. Promising developments in the analytical chemistry of PCBs in foods include the implementation of new extraction techniques to reduce analysis time. However, there are indications that these novel techniques may lead to systematical errors in the data, thus complicating and confusing risk and exposure assessments. The findings from this project will assist in the impartial comparison of PCB data.

This study has been completed and the results compiled. At a workshop held on the 27-28 April 2000, and hosted by the Institut Quimic de Sarria in Barcelona, Spain, rapporteurs were appointed to write a report to be submitted to JAOAC International.
