| 摘 要： | 以GC/ECD测定江汉平原中部24个表层土壤中25种有机氯农药的含量。所有有机氯农药均有检出,其中含量最高的是DDT类农药,HCHs类农药含量规律为δ-HCH>α-HCH>β-HCH>γ-HCH。研究区域农药含量较国内其他地方来说污染较低。通过成分的不同含量比较,发现该地区农药除了早期污染外,近期也有新的污染源。

| Abstract: | A survey of soil pollution relating to organochlorine pesticides(OCPs)contained in topsoil in the central Jianghan Plain was conducted.The survey involved amounts of work,i.e.sample-collecting and sample processing,as well as analysis by GC/ECD.As a result,25 kinds of organochlorine pesticides were detected,which indicated residues of OCPs such as DDTs,HCHs,chlordane and endosulfan,especially DDTs,HCHs were mostly attributed to historical application,while heptachlor belonged to the application in recent years.In general,compared to the situation in most part of the country,soil pollution by OCPs in the central Jianghan Plain was categorized as low pollution level. |
