| 摘 要： | 分析调查了中国部分海域海水中溶解态有机氯农药(OCPs,25种)和多氯联苯(PCBs,6种)的残留分布特征。结果表明,所有采样点都不同程度地受到了OCPs和PCBs的污染,其中福建省福州平潭和莆田湄洲岛的OCPs污染较为严重,浓度分别达到1752.59和796.19 ng/L;而辽宁省的大连老虎滩OCPs污染较轻,浓度为53.63 ng/L。各采样点海域海水中HCHs污染程度一般高于DDTs,HCHs主要以早期残留为主;根据DDT/DDTs的比值推测,在福州平潭、莆田湄洲岛和珠海淇澳岛水体显示有新的DDT输入。在各海域水体中溶解态PCBs的浓度为33.55~474.92 ng/L,均超过了美国环保局规定的海水浓度限值。因此目前我国沿海海域水体中持久性有机污染物有机氯农药和多氯联苯污染仍不能忽视。

| Abstract: | The concentrations of organochlorine pesticides(OCPs,25) and polychlorinated biphenyls(PCBs,6) in seawater collected from China coast were investigated.The results showed that concentrations of OCPs ranged from 53.63 to 1752.59 ng/L in seawater,and the highest value was in Pingtan(Fuzhou) while the lowest value was in Laohutan(Dalian,Liaoling province).At all of sampling sites,the concentrations of DDTs and HCHs were lower than the limits of national seawater quality standards(class 1),and the concentration... |
