Environmental samples contaminated with elemental sulfur(waters 22, sediments 20, crucian carps 19) collected from Soho Lake during the period of Sep. 1981 to Apr. 1982 were analyzed for polychlorinated biphenyls(PCBs) and organochlorine insecticides by GLC-ECD. Elemental sulfur was found to interfere in the residue analysis of environmental samples and the sulfur was eliminated, prior to analysis, with copper powder. PCBs residues in Soho lake were temporarily characterized as Aroclor 1254 and were analyzed at minimum detectable quantity of 0.04 ng by derivatizing PCBs to decachlorobiphenyl(DCB). PCBs were positively detected in all samples and its residue levels in waters, sediments, and crucian carps were
