摘要：

[目的]了解北江佛山段饮用水源HCHs和DDTs的含量和季节分布。[方法]在不同季节北江佛山段的北江、石塘、金沙和石湾4个饮用水厂取水口取水样,参照美国EPA方法进行HCHs、DDTs检测分析。[结果]HCHs平均含量为1.125 ng/L,DDTs平均含量为0.267 ng/L,枯水期高于丰水期;不同结构HCHs中,α/γ平均比值为0.99,(α+γ)/β平均比值为1.99;(DDD+DDE)/DDT平均比值为1.03,DDD/DDE平均比值为1.10。[结论]北江佛山段饮用水源中HCHs和DDTs污染水平均低于国标(GB3838-2002),北江佛山段流域存在新的HCHs和DDTs污染源,水体处于厌氧环境。

摘要：

[Objective] To understand the concentration and seasonal distribution of HCHs and DDTs in the drinking water source of Foshan section of Bei River.[Method] Water samples were taken at the sample opening of drinking water source in Beijiang,Shitang,Jinsha and Shiwan water stations on Foshan section of Bei River in different seasons,and HCHs and DDTs in the water samples were analyzed by the methods referring to the American EPA.[Result] The average concentrations of HCHs and DDTs were 1.125 ng/L and 0.267 ng/L respectively,the pollutant levels were higher in the low water season than in high water season;the average values of α/γ and(α+γ)/β were 0.99 and 1.99 respectively among the different formations of HCHs,and the average values of(DDD+DDE)/DDT and DDD/DDE were 1.03 and 1.10 respectively.[Conclusion] The pollution levels of HCHs and DDTs in the drinking water source in Foshan section of Bei River were lower than the state standards(GB3838-2002 Environmental quality standards for surface water);there were new pollute source of HCHs and DDTs in the area of Foshan section of Bei River,and the water was in the anaerobic conditions.
