摘要:应用高通量分析方法对大清河流域47个沉积物中的潜在风险有机污染物进行了分析,共筛查到104种有毒有机污染物。应用基于风险分析的筛查体系对检出率高于10%的54种污染物进行了概率风险评估,筛查出11种具有潜在风险的流域优先有机污染物,包括农药(特草克、氨磺磷、枯莠隆)、工业用品及副产物(二苯胺、9,10-蒽醌、萘、2-甲基萘)及家庭及个人护理品(咖啡因、苯乙酮、苯甲酮、联苯)等。结果表明,基于风险分析的流域污染物筛查方法体系可成功地对流域内优先污染物进行识别与筛查,为流域管理提供科学依据。

Abstract:A high throughout screening method was applied to screening the organic pollutants in 47 sediments from the Daqinghe River Watershed. A total of 104 organic contaminants were identified, of which 54 were detected at more than 10% sites. The developed risk-based screening procedure was used for priority setting of the 54 contaminants and the probability of risk was calculated. The results showed that 11 contaminants were selected as priorities in the Daqinghe River Watershed. These were pesticides, industry chemicals, and home and personal care products. This study has proved that the developed risk-based screening procedure has the ability of identifying and ranking the priority pollutants in the environment at the watershed scale.
