| 摘 要： | 分析了鄱阳湖康山沉积物中的有机氯农药残留情况，发现样品中DDT及其代谢产物、HCH的异构体和六氯苯部分被检出。其中δ-HCH、γ—HCH、β-HCH的残留水平最高，平均值分别达到0．42．g／g、0．35ngg和0．27g／g（干重），沉积物的HCHs含量明显高于DDTs。有机氯农药的主要来源为地表径流入湖、大气沉降和工业污水排放。根据风险评估值进行对比，鄱阳湖沉积物中有机氯农药的生态风险较低。 |

| Abstract: | This study analyzed chlorinated pesticides of sediments in Poyang Lake. The DDT, DDE, DDD, HCH isomers, Hexachlorophene were measured some of samples. δ-HCH,γ-HCH and β-HCH had higher concentrations than others. The average values of them were 0.42 ng/g,0.35 ng/g and 0.27 ng/g, respectively. HCHs in sediments were higher than DDTs. The organochlorine residues in sediments mainly originated form the runoff, atmospherically deposition and industrial sewage. According to the ERL and ERM value of risk evaluation for ocean which can also be applied for lake, sediments in Poyang Lake pose a low risk to consumers of bottom feeders. |
