WHO Coordinated Proficiency Study for the Determination of PolychlorinatedBiphenyls, Dibenzodioxins and Dibenzofurans in Human Milk and Blood, Cow's Milk and Fish. Results of the Participation of RIVM-LOC in the III+ d Round

摘要

This report summarizes the results of the participation of the Laboratory ofOrganic Analytical Chemistry, National Institute of Public Health and Environmental Protection in an international interlaboratory comparison study on the analysis of polychlorinated biphenyls (PCBs), dibenzodioxins (PCDDs) and dibenzofurans (PCDFs) in human milk, human blood, cow's milk and fish. The round robin study was organized by WHO Regional Office of Europe, Copenhagen. Qualified were the RIVM methods for PCDD/Fs in human milk, human blood and fish and for PCBs including the indicator PCBs, mono ortho PCBs and planar PCBs in human milk. There was considerable criticism on the statistical methods used. These methods will be peer reviewed. Possible changes in qualification results will be implemented.
