The Japan Society for Analytical Chemistry carried out a third proficiency test for the determination of dioxins (polychlorodibenzo-p-dioxins, polychlorodibenzofurans and coplanar polychlorobiphenyls) in marine sediment. Proficiency testing of analytical laboratories is based on ISO/IEC Guide 43-1, "Proficiency testing by interlaboratory comparisons". This testing was carried out from May '02 to August '02, with the participation of 104 laboratories. The test results were : 37.05 pg-TEQ/g of total Dioxin concentration on average ; 7% in robust coefficient of variation. A total of 9 labs have been estimated to be unsatisfactory due to their large z score in the robust method, over 3 in absolute value.
