Occurrence and Source Apportionment of HCHs and DDTs in Aquatic Environment of Foshan Section of Bei River
摘要
Abstract
[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.关键词
