| 摘 要： | 土壤中持久性有机污染物往往与重金属共存形成混合污染,但过去的研究较少关注它们在土壤中的相互影响。本研究选择典型铜污染区农田,分析了铜不同污染程度的表层土壤中HCB、HCHs与DDTs等持久性有机氯农药的组分及含量。结果表明:DDTs在土壤中的残留量随着土壤铜污染程度的加剧而上升;土壤中铜抑止了DDT向DDE或DDD的转化,DDTs残留量相对较大。供试土壤中持久性有机氯农药含量与有机质之间的相关性分析表明,污染土壤中两者之间的相关性大于未污染土壤,说明铜促进了土壤中的DDTs和HCHs与土壤有机质结合,这可能是导致水田土壤中DDTs的平均含量显著高于旱地和林灌地土壤的原因之一。 |

| Abstract: | Soil pollution mixed by persistent organic pollutants(POPs) and heavy metals is widely distributed in farmland.However,little attention has been paid to their interaction in soil.Surface soil samples were collected from a typical copper-contaminated farmland in Fuyang of Zhejiang province and analyzed for organochlorine pesticides(OCPs),such as HCB,HCHs and DDTs.The results showed that soil total content of DDT increased with the degree of copper contamination in soil probably as a result of an inhabitation... |
