海水利用排放水中典型有机氯农药的环境安全性

基于生态风险评价方法对海水淡化和直流冷却两类海水利用工程排放水中的3类典型有机氯农药进行了环境安全性分析。通过实际监测获得有机氯农药在海水利用排放水中的环境浓度；借助美国环境保护署（EPA）颁布的水质基准，获得有机氯农药在海水中的无影响浓度；采用商值法对海水利用排放水中的有机氯农药环境风险进行量化。结果表明：海水利用排放水中七氯和滴滴涕已存在环境风险，其中七氯的污染问题应尤引起重视。

Environmental Safety on Typical Organochlorine Pesticides in the Drain of Seawater Utilization

The environmental safety analysis on three typical organochlorine pesticides in the drain of seawater utilization was introduced based on ecological risk assessment.The environmental concentrations of organochlorine pesticides in the drain were obtained by collecting and testing the samples.The no effect concentrations were obtained through Water Quality Criteria of EPA.The environmental risk was quantized in quotient method.The result was shown that DDT and heptachlor had environmental risk.More attention should be paid on heptachlor.
