“六六六”农药禁用后,甲胺磷(O,S—二甲基硫酐磷酰胺)作为取代性农药.它是一种高效、高毒的广谱性杀虫、杀螨剂,有触杀、胃毒和内吸收作用。由于它对人、畜有剧毒,且是一种水溶性农药,易被植物吸收,因此,研究其在水稻上的残留情况有重要意义。通过~(35)S-甲胺磷在水稻上残留试验研究,得出甲胺磷在水稻上的半衰期为8～9天,各部位的残留量不均匀,早、晚稻中的残留量不同,并推算出残留量没有超过1985年FAO/WHO公布的允许摄入量。
Methamidophos (O, S-dimethylsulfhydryl phosphoramidate) is a substituted pesticide after banning the “BHC” pesticide, which is a kind of broad spectrum insecticide and acaricide with Touch, stomach poisoning and internal absorption. Because of its toxic to humans and animals, and is a water-soluble pesticide, easily absorbed by plants, therefore, to study its residue on rice is of great significance. Through the study on the residue of ~ (35) S-methamidophos in rice, the half-life of methamidophos in rice was 8-9 days, the residues in different parts were not uniform, the residues in early and late rice were different, And calculated that the residue did not exceed the allowable intakes published by the FAO / WHO in 1985.
