-
摘要: 本文根据作物对六六六、滴滴涕的吸收量和吸收率,以及在土壤、水和空气中的残留状况,探讨了六六六、滴滴涕的土壤标准制定方法。在此,六六六、滴滴涕的土壤标准定为0.4和0.5ppm比较适合中国的情况。Abstract: The maximum allowable concentrations of BHC and DDT in soils were assessed in this study. Based on amounts and rates of BHC and DDT absorbed by crops and residues in soils, water and air, the maximum allowable concentrations for BHC and DDT in soils of China should be set at 0.4 and 0.5 ppm. These values are appropriate to the codition of China.
