Hexachlorocyclohexanes (α, β, γ and δ HCH), DDT group (p,P′ DDE, o,P′ DDT, p,P′ DDD and p,P′ DDT) and polychlorinated biphenyls (PCBs) were analyzed. The concentrations of ∑HCH ranged from 3 13 ng/g to 7 02 ng/g and those of ∑DDT ranged from 0 16 ng/g to 1 28 ng/g. 14 individual PCB congeners, each in the range of 0 01 0 12 ng/g, were detected and the concentration of ∑PCB was from 0 14 ng/g to 0 60 ng/g. Also, the results were compared with the data reported previously.展开更多
