根据我国《农药毒性试验方法暂行规定》的程序和方法对我省化工研究所新合成的高效有机磷农药棉安磷进行了急性、蓄积毒性和致突变试验研究。结果显示35％棉安磷工业品对大鼠经口和皮急性毒性LD_(50)分别为6.3(3.16～12.6),36.38(27.74～47.51)mg/kg,纯品棉安磷分别为2.95(1.48～5.89),3.14(2.77～3.56)mg/kg,均属高毒 According to the procedures and methods of Interim Provisions on Pesticide Toxicity Tests in China, the acute toxicity, cumulative toxicity and mutagenicity of cotton organophosphate, a newly synthesized high efficient organophosphorus pesticide in our province, were studied. The results showed that the acute oral toxicity and the acute toxicity LD_ (50) of cotton industrial phosphorus 35% were 6.3 (3.16 ~ 12.6) and 36.38 (27.74 ~ 47.51) mg / kg, 1.48 ~ 5.89), 3.14 (2.77 ~ 3.56) mg / kg, are highly toxic
