抚仙湖水体中芳香烃、卤代烃及有机氯农药残留量的研究

为了解抚仙湖水体中芳香烃、卤代烃的含量及有机氯农药的残留量，评价水质的优良度，以苯、甲苯、二甲苯、苯并（ａ）芘、氯仿、四氯化碳、滴滴涕、六六六为代表性指标进行了调查研究，结果表明，湖水未受苯、二甲苯、苯并（ａ）芘、氯仿及滴滴涕的污染，但受甲苯污染，局部水域受四氯化碳污染（未超标），各水域均检出六六六，但个别水域六六六残留量超标。

The Study on the Residual Levels of Aromatic Hydrocarbon ,Halohydrocarbon and Organochlorine Pesticides in the Water of Fuxian Lake

To study the residual levels of aromatic hydrocarbon,halohydrocarbon and organochlorine pesticides in the water of Fuxian lake,the levels of representative pollulants,such as benzene,mythylbenzene,dimethylbenzene,benzo]pyrene,trichloromethane,carbon tetrachloride, dichcoro diphenyi trichloroethane(DDT) and benzene hexachloride(BHC)were determined for the assessment on the water quality of Fuxian lake in Yunnan province.The results showed that the water body had been polluted by methylbenzene,but not by benzene,dimethylbenzene,benzo pyrene,trichloromethane and DDT.Some areas of the water body had been polluted by carbon tetrachloride,but the levels of which did not exceed the hygienic standard for drinking water.The BHC was found in every sampling areas,the levels of residual BHC exceedcd the hygienic standard for drinking water in some areas.
