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。 In order to understand the content of aromatics, halocarbons and organochlorine pesticides residues in Fuxian Lake water body, and to evaluate the goodness of water quality, benzene, toluene, xylene, benzo (a) pyrene, chloroform, carbon tetrachloride , DDT, and BHC were investigated. The results showed that the lake was not contaminated with benzene, xylene, benzo (a) pyrene, chloroform and DDT, but was contaminated with toluene. Some waters were affected by tetrachloride Carbon pollution (not exceeded), all sixty-six were detected in the waters, but some 666 residues exceeded the water area.
