二氯甲烷可用以代替苯作为脱漆剂。本文报告我们对二氯甲烷毒性的一些实验研究结果。一、急性毒性实验:用99.9%纯度的二氯甲烷对小鼠(18～23g体重)70只急性吸入染毒2小时,观察2周,结果发现二氯甲烷具有麻醉和呼吸道刺激作用。半数致死量为64.03(66.06～62.07)mg/L。二、二氯甲烷对大鼠22只经呼吸道或消化道染毒2小时后,血液碳氧血红蛋白(COHb)
Dichloromethane can be used instead of benzene as a paint remover. This article reports some of our experimental results on the toxicity of methylene chloride. 1. Acute Toxicity Experiment: Toxicity of 70 acute inhalation mice (18-23g body weight) with 99.9% dichloromethane for 2 hours was observed for 2 weeks. It was found that methylene chloride had anesthesia and respiratory irritation. The median lethal dose was 64.03 (66.06 ~ 62.07) mg / L. Second, dichloromethane 22 rats by the respiratory tract or digestive tract exposure 2 hours after the blood carboxyhemoglobin (COHb)
