Mollusks living in seas can accumulate organochlorine pesticides (OCPs). The residue levels of selected OCPs: dichlorodiphenyltrichloroethane (p,p'-DDT, o,p'-DDT, p,p'-DDE, p,p'-DDD), hexachlorocyclohexanes (alpha-, beta-, gamma- and delta-HCH) in gastropod and bivalve species collected from ten coastal cites along the Chinese Bohai Sea were investigated from 2002 to 2004. The species included nine kinds of mollusks: Rapana venosa, Neverita didyma, Scapharca subcrenata, Mytilus edulis, Amusium, Crassostrea talienwhanensis, Meretix meretrix, Sinonovacula constricta, Ruditapes philippinarum, Mactra veneriformis. The results showed that OCPs widely existed in the mollusks organisms. p,p'-DDT, p,p'-DDE, beta-HCH were the major compounds. Statistical analysis (One-way ANOVA) showed that the contents of OCPs in these mollusks did not change obviously from 2002 to 2004. Principal component analysis (PCA) was also used for determining the polluting characters existing in this selected field.
生活在海洋中的软体动物会蓄积有机氯农药（OCPs）。2002年至2004年期间，对从中国渤海沿岸十个城市采集的腹足类和双壳类物种中选定的有机氯农药残留水平进行了调查，这些农药包括：二氯二苯三氯乙烷（p,p'-滴滴涕、o,p'-滴滴涕、p,p'-滴滴伊、p,p'-滴滴滴）、六氯环己烷（α-、β-、γ-和δ-六六六）。所涉物种包括九种软体动物：疣荔枝螺、脉红螺、毛蚶、紫贻贝、波纹巴非蛤、大连湾牡蛎、泥蚶、缢蛏、菲律宾蛤仔、四角蛤蜊。结果表明，有机氯农药在软体动物体内广泛存在。p,p'-滴滴涕、p,p'-滴滴伊、β-六六六是主要化合物。统计分析（单因素方差分析）表明，2002年至2004年期间，这些软体动物体内有机氯农药的含量没有明显变化。还采用主成分分析（PCA）来确定该选定区域存在的污染特征。
