摘要
1991、1992年在河南、河北等省施用林丹防治小麦害虫地区跟踪监测:林丹在小麦及土壤中的残留量全部符合标准。土壤及小麦中残留量中位数分别为50.8μg/kg和11.9μg/kg.土壤中滴滴涕残留量偏高,是由于防治红蜘蛛时施用三氯杀螨醇,而三氯杀螨醇原药中含有滴滴涕所致。
The tracing monitoring data of Lindane applied to prevent pest on wheat field in Henan and Hebei provinces in 1991 and 1992, showed that the residual, values of Lindane in soil and corn accorded with the environmental standards; and were 50.8 μg/kg and 11.6μg/kg respectively. The residue of DDT in soil is rather high due to the application of the pesticide Kelthane to prevent and kill red spider on the wheat field and the pesticide Kelthane contains DDT.
