摘要
为了解黔南地区表层土壤中有机氯农药(OCPs)残留的污染状况,对采集自12个县市97份土壤样品进行了残留状况分析。结果表明:已停用的六六六(HCHs)、滴滴涕(DDTs)都仍有检出,样品中ΣOCPs残留量范围为未检出至8.99μg/kg,其中ΣHCHs和ΣDDTs为检出率最高的主要污染物,均值分别为1.31μg/kg和0.50μg/kg;与国内其他地区报道相比,黔南地区OCPs残留水平较低。
In order to study the pollution status of organochlorine pesticide （OCPs） residues in topsoil in southern Guizhou,97 soil samples from 12 counties in southern Guizhou were collected and analyzed.The detection results showed that the banned HCHs and DDTs were detected,the ∑OCPs residues range was from not detected to 8.99 μg/kg,among them,∑HCHs and ∑DDTs had the highest detection rate as main pollutants,with average values of 1.31 μg/kg and 0.50 μg/kg.It could be concluded that OCPs residues level was lower in southern Guizhou compared with reports of other areas.
