摘　　要：利用GC ECD对长江口滨岸潮滩中动物进行研究 ,分析了PCBs和OCPs(DDTs和HCHs)的含量分布 .结果表明PCBs含量水平为 4 3 7～ 12 6 0 4ng/ g ,均值为 342 5ng/ g ;DDTs为 1 5～ 15 9 4ng/g ,均值为 33 7ng/ g ;HCHs为 0 9～ 77 0ng/ g ,均值为13 0ng/ g .从空间上看 ,同种动物对不同污染物的累积和同种污染物在不同动物体内的累积均无明显的规律 ,但同属种样品则有雄性个体污染物含量高于雌性个体、小个体高于大个体的规律 .对动物体内POPs污染进行了初步评价 ,结果显示 :该区动物均不同程度地受到污染 。Polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) in the animals of the Yangtze estuarine and coastal areas were determined with GC-ECD. The results showed that the concentration distribution of PCBs ranged from 43.7 to 1260.4ng/g, with an average value of 342.5ng/g;1.5～159.4 ng/g and 33.7ng/g for DDTs;0.9～77.0ng/g and 13.0ng/g for HCHs. The spatial distribution patterns of different contaminants in the same animal species and the same pollutant in the different animal species didn't follow obvious laws. Whereas, animals of the same species were characterized by higher contamination levels for males than females, and the small individuals than large ones. Compared with other areas at home and abroad and low-high level limits, a preliminary assessment was presented. As a result, it was shown that there existed a moderate level, to some extent, with the contamination in the animals from the study area.
