有机氯农药在中国环境介质中的分布

Distribution of Organochlorine Pesticides(OCPs) from Various Environmental Media in China

系统地总结了我国不同环境介质中有机氯农药(OCPs)的污染水平及其特点,并分析了其存在的生态风险。结果表明:我国水体已普遍受到OCPs污染,其中大亚湾和海河等部分水域污染比较严重;沉积物中OCPs大多处于较高的生态风险水平,厦门西港等地污染比较严重;土壤和大气中OCPs含量较低,污染生态风险较小;生物体中OCPs含量也较低,但长期食用仍存在较大的生态风险。

This paper provides residue level of OCPs from various environmental media in China. In addition, potential ecological risks of OCPs are evalutated. The results show that, on a national basis, OCPs levels in are relatively high and a high biological impairment is most likely to be posed in China, especially in some aquatorriums, such as Daya Bay and Haihe River. The concentration of OCPs in sediments tends to be a relatively higher risk in most areas, such as Xiamen Western Bay. With the small amount of investigation in China, OCPs pollution associats with low adverse biological effects in soils and atmosphere. Also with smaller content of organisms in China, but long-term edible still has the high risks.
