| 摘 要： | 以西溪湿地为主要研究区域,采集了西溪湿地主要河口的表层和柱状底泥样品,以气相色谱(GC)/电子捕获检测器(ECD)定量测定样品中滴滴涕(DDTs)、六六六(HCHs)的含量,并对其进行生态风险评价.结果表明:(1)西溪湿地底泥样品中DDTs浓度明显比HCHs高.有机氯农药(OCPs)在研究区域内的底泥表层样品中残留呈现...

| Abstract: | The concentration of organochlorine pesticides(OCPs),such as HCHs and DDTs,in sediments of Xixi Wetland in Hangzhou was analyzed by GC/ECD.Distribution characteristics and biological risk evaluation of OCPs were also investigated.Vertical distribution of OCPs in column sediments was discussed.Results showed that in sediment of Xixi Wetland,the concentration of DDTs was higher than HCHs.Because of river confluence and artificial factors,OCPs in surface sediments of study area presented the characters of unba... |
