| 摘 要： | 介绍了国内外持久性有机物的研究进展，分析了中国典型地区中的持久性有机污染物的分布情况，其中淮河中下游的PAHs含量较高，而大连湾检测出的DDTs和PCBs含量均高于其他地区。持久性有机污染物可以在动植物体内不断富集，据分析，有机污染物在鱼类的富集因子可高达1124．1，持久性有机污染物通过食物链的富集逐级放大，对全球生态构成潜在巨大的威胁。近年来，由于持久性有机污染物的影响，在世界各地出现了动物的死亡、甚至灭绝的现象，而且有机污染物在人体内的蓄积，会对人体产生极大的的影响。最后，就当前存在的问题，提出了对策与建议，指出了该领域的发展方向。

| Abstract: | This paper introduced the development of persistent organic pollutants(POPs)in the world,and described the distribution of persistent organic pollutants in typic area of our country,PAHs in middle and lower reaches of huai river was higher,and DDTs and PCBs were higher in Dalian lough than that in outer areas.POPs can be enriched in propagation continually.According to analysis,the BCF of POPs in fish was up to 1124.1,POPs was enriched by food chain,and brought tremendous threaten to ecosystem.As a result o... |
