| 摘 要： | 对长江入海口包括江苏启东,上海崇明岛、长兴岛、横沙岛等地区的浅层沉积物中典型有机氯农药(OCPs)的分布情况进行了研究。采用气相色谱-电子捕获检测器进行检测,方法检出限为0.10 ng/g,回收率为62.4%～116.7%,精密度(RSD)为2.7%～8.3%。调查分析结果显示,长江入海口沿岸均存在轻度和中度的OCPs污染,主要检出物总滴滴涕(DDTs)浓度范围为1.22～626.43 ng/g。深度(0～80 cm)采样检测结果表明,研究区表层及深度样品中DDTs均有不同程度检出,浅层沉积物中DDTs在0～20 cm区域占检出总量的58.1%;其次是20～40 cm区域,DDTs占总量的30.8%;40～60 cm区域DDTs占总量的8.2%;60～80 cm区域DDTs占总量的2.9%,即浅层沉积物中DDTs主要集中在0～40 cm区域,部分点位40～80 cm能够检出少量DDTs。本研究提供的数据为该地区OCPs垂直分布提供参考。

| Abstract: | The typical organochlorine pesticides(OCPs) distribution of the Yangtze River estuary was studied for shallow sediments from Qidong Jiangsu,Chongming Island,Changxing and Hengsha Island Shanghai.The detection limit is 0.10 ng/g,the recovery of samples are 62.4%-116.7% and the relative standard deviation(RSD) are 2.7%-8.3% by using Gas Chromatography equipment with electron capture detector(ECD).Research results indicate that mild and moderate contamination of OCPs did exist along the coast of Yangtze River ... |
