随着农业生产的发展,植保工作相应加强,越来越离不开农药。与此同时,人们对施用农药造成的环境污染及对人类健康带来的威胁深感忧虑。因此,农药的“三致性”(致畸性、致癌性和致实变性)已成为人们迫切需要解决的难题。 残留的农药,几乎无所不在——大气、水系、土壤、动物、植物。据报道,科学家在从没有使用过农药的南极洲、珠穆朗玛峰上竞也检出了农药的残留。那么,这些人迹罕到之处农药从哪里来呢?残留的农药一方面来自施入的农药或人倒出的、事故的、工业的污水,这些农药或污水直接污染了环境和动、植物,虽然农药在一定条件下可受外界环境变化的影响或活体酶系的作用逐渐被降解,但降解的速度差别很大。有些性质稳定且毒性大的农药,其残毒问题就较 With the development of agricultural production, plant protection work correspondingly strengthened, more and more inseparable from pesticides. At the same time, people are deeply concerned about the environmental pollution caused by pesticides and their threats to human health. Therefore, the “consistency” (teratogenicity, carcinogenicity and degeneracy) of pesticides has become an urgent problem to be solved. Residual pesticides, almost everywhere - the atmosphere, water, soil, animals, plants. It is reported that scientists also detected residues of pesticides in Mount Everest from Antarctica, where no pesticides have been used. Then, where are the pesticides come from? What are the pesticide residues? The pesticide residues on the one hand come from the pesticide or man-in-the-coming, accidental and industrial waste water that is directly contaminated by the pesticides or sewage, which pollute the environment, animals and plants, Although under certain conditions, pesticides may be gradually degraded by changes in the external environment or in vivo enzyme systems, the rate of degradation varies greatly. Some pesticides that are stable and toxic in nature have more residual problems
