为评价江苏省滩涂沉积物中有机氯农药的残留状况，采集了16个表层沉积物样品。总体而言，共检测到22种有机氯农药，其总浓度范围从0.96至12.14纳克/克（干重）不等。总六氯环己烷（HCH）和总二氯二苯三氯乙烷（DDT）水平分别为<0.01至0.67纳克/克和0.23至4.85纳克/克。滴滴涕是主要化合物。β-HCH的优势表明HCH的污染历史。根据（p，p′-DDD+p，p′-DDE）/p，p′-DDT和do，p′-DDT/p，p′-DDT的比值，大部分样点没有出现新的DDTs输入，主要来源是历史上使用的技术性DDTs。OCPs如狄氏剂、异狄氏剂、p，p′-DDD和p，p′-DDT等均超过了低效应范围，在研究区的某些地点偶尔会出现不良生物效应。
Sixteen surface sediment samples were collected and analysed to evaluate the residues of organochlorine pesticides (OCPs) from intertidal flat in Jiangsu Province. Overall, 22 OCPs were detected with total concentrations of OCPs ranging widely from 0.96 to 12.14 ng/g (dry wt). Total hexachlorocyclohexane (HCH) and total dichlorodiphenyltrichloroethane (DDT) levels varied from <0.01 to 0.67 ng/g and from 0.23 to 4.85 ng/g, respectively. DDTs were the predominant compounds. The dominance ofβ-HCH indicated a history of HCH pollution. According to the ratios of (p,p′-DDD+p,p′-DDE)/p,p′-DDT ando,p′-DDT/p, p′-DDT, new input of DDTs did not occur in most sites, and the main sources were historical usage of technical DDTs. OCPs such as dieldrin, endrin,p, p′-DDD, andp, p′-DDT exceeded the effects range low, showing adverse biological effects that would occasionally occur at some sites of the study area.
