English Abstract This report summarises the results of the participation
of the Laboratory of Organic 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 organised
by WHO Regional Office for 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.
Not qualified were the determination of PCDD/Fs in cow's milk due to a
penalty for missing data and for PCBs in cow's milk and fish due to an
insufficient agreement with the median values of the study. There was
considerable critism on the statistical methods used. These methods will be
peer reviewed and modified accordingly as wel as resulting possible changes
in qualification results will be implemented.
