摘要
为了了解城市中有机氯农药残留现状,分析了有机氯农药的污染源。2007年4月至2008年7月在应城市辖区内采集了农产品及其生长环境样品10类622份,人体生物材料样品42份,依据国标方法进行了DDT、HCH异构体含量检测。分类样品的各类异构体检出率差异明显,应城市存在新的HCH、DDT输入源,人体生物材料样品有机氯残留异构体特征均为降解终端状态。最后提出了应对农药残留的有效措施。
To acquaint the pesticide residue status of organochlorine,the sources of pollution of organochlorine pesticide were analysed.A total of 622 samples of 10 categories of agricultural products and their growing environments,and 42 biological samples of the human body were collected in Yingcheng during April in 2007 to July in 2008.The content of DDT,HCH isomer were determined according to the national standards.The detection rate of organochlorine isomer differed significantly in different kinds of samples.Th...
