杀螟松(Fenitrothion)是一种广谱有机磷杀虫剂,对大白鼠的经口LD50雄鼠为501mg/Kg,雌鼠为584mg/Kg。据国外资料报导,以0.01—1mg/蛋的剂量孵化的第4～12天处理来亨鸡胚,孵出的小鸡出现人体畸形。工业杀螟松0.3mg/Kg及1.0mg/Kg(体重)喂饲妊娠早期白兔、体重、死胎率、胎仔外形及骨骼均无明显可见改变。国产杀螟松对动物生殖和胚毒以及致畸作用未见公开报导。为此,我们对浙江宁波化工研究所提纯供给的杀螟松原油(含量96.42％)进行此项实验研究。 Fenitrothion is a broad-spectrum organophosphate insecticide with 501 mg / kg for oral LD50 male rats and 584 mg / kg for female rats. According to foreign data reported to the first dose of 0.01-1mg / egg 4 to 12 days to deal with Hengye chicken embryos, hatched chicks appear human malformations. In the first trimester of pregnancy, rabbits fed fenitrothion 0.3mg / kg and 1.0mg / kg (body weight) had no significant change in body weight, stillbirth rate, fetal shape and bones. Domestic fenitrothion on animal reproduction and embryo toxicity and teratogenic effects have not been publicly reported. For this reason, we carried out this experimental study on the fenitrothion crude oil (content 96.42%) purified and supplied by Zhejiang Ningbo Chemical Research Institute.
