大、小鼠的急性毒性LD_(50)分别为53.91和18.65mg/kg,属高毒物质。亚慢性毒性试验大鼠经口无作用剂量为0.05mg/kg。该品具胚胎毒性,致突变呈阳性。~3H氧化乐果在大鼠体内毒时曲线属二室开放模型。空气中氧化乐果浓度在0.3mg/m~3以下,工人全血ChE活力与对照组相比无差异。氧化乐果车间最高容许浓度的建议值为0.3mg/m~3(皮)。
The acute and acute LD_ (50) of mice and mice were 53.91 and 18.65 mg / kg, respectively, which were highly toxic substances. Sub-chronic toxicity test rat oral no effect dose of 0.05mg / kg. The product embryo toxicity, mutagenicity was positive. ~ 3H omethoate poisoning in rats when the curve is a two-compartment open model. The concentration of omethoate in the air is below 0.3mg / m ~ 3, there is no difference in the ChE activity of whole blood of the workers compared with the control group. Omethoquin workshop maximum allowable concentration of the recommended value of 0.3mg / m ~ 3 (skin).
