Abstract:

采用GC-ECD对太湖表层沉积物中的有机氯农药含量进行了定性定量分析.太湖20个采样点均有不同程度的有机氯农药检出,16种有机氯农药总量为4.22-460.99ng/g(dw),北部湖区、湖心区以及沿岸区等均有高值点出现,与沉积物有机质含量、氮磷营养盐含量分布并不一致.检出率最高的有机氯农药组分为DDTs、HCHs.DDTs含量检出顺序为p,p'-DDT﹥p,p'-DDD﹥p,p'-DDE,说明环境中可能仍然具有DDT输入特征;HCHs中α-HCH,γ-HCH检出相当,β,δ-HCH检出较高,主要为早期残留.结合鼠伤寒沙门氏菌/哺乳动物微粒体酶系(Ames)试验研究太湖典型湖区表层沉积物中有机污染物的遗传毒性,初步确定可能的生态风险因子.
