应用各种农药为提高农产量的重要措施之一。农药中包括杀虫剂、杀菌剂、杀鼠剂、除莠剂及生长刺激素等。有些农药对人畜有毒害作用,在杀虫剂中以有机磷、有机汞、有机氯及无机砷化合物等危害较大,若不注意防护,往往引起中毒。一般性状有机磷化合物作为农业杀虫剂,现使用较广者为1605、1059、3911、1240、4049及敌百虫等。其中毒机制、临床表现及防治方法均相似;毒性强弱稍有差异,其中以1240、4049及敌百虫毒性较低。我国各地使用最多者为1605及1059,现以1605为代表,略介绍其性状:1605德人称 E605,为硫代磷酸酯化合物,化学结构名称为硫代磷酸对硝基苯二乙酯,通称 Parathi- Application of various pesticides to improve agricultural production is one of the important measures. Pesticides include insecticides, fungicides, rodenticides, herbicides and growth-promoting hormones. Some pesticides are poisonous to humans and animals. In pesticides, organic phosphorus, organic mercury, organochlorines and inorganic arsenic compounds are more harmful. If they do not pay attention to protection, they often cause poisoning. General characteristics of organic phosphorus compounds as agricultural insecticides, is now widely used 1605,1059,3911,1240,4049 and trichlorfon and so on. Its poisoning mechanism, clinical manifestations and control methods are similar; slightly different toxicity, of which 1240,4049 and trichlorfon toxicity is low. The most commonly used throughout China are 1605 and 1059, are represented by 1605, a brief description of its traits: 1605 German called E605, for phosphorothioate compounds, the chemical structure of the name of p-nitrophenyl diethyl phosphorothioate, commonly known as Parathi -
