对欧洲和美国地下水的监测表明,农药残留物不仅出现在农田浅层地下水中,也存在于深层地下水中。在许多国家进行农药登记时,农药淋溶对地下水的危害是一个十分重要的考察项目。例如,在欧共体,地下水农药残留量指标应不大于0.1μg/L,或者应满足最新毒物学指标的规定。这些是考虑到可能作为饮用水的地下水的安全性,即使是非常小的一部分(所施用农药)淋溶至地下水,就可能超标。 本文对农药进行评价时,首先讨论了农田浅层 Monitoring of groundwater in Europe and the United States shows that pesticide residues are found not only in shallow groundwater in farmlands but also in deep groundwater. In many countries pesticide registration, pesticide leaching on the harm of groundwater is a very important inspection project. For example, in the European Community, the indicator of groundwater pesticide residues should not exceed 0.1 μg / L, or should meet the latest toxicological specifications. These are likely to exceed the standard even if a very small part of the applied groundwater is leached into the groundwater, taking into account the safety of groundwater that may be used as drinking water. In this paper, pesticide evaluation, the first to discuss shallow farmland
