三氯化磷经口灌胃属中等毒级,经呼吸道吸入属高毒级。引起大鼠肺巨噬细胞损害的急性阈浓度为 686.8mg/m~3。属危害性I级及强刺激化合物。亚急性阈浓度为2mg/m~3。建议我国三氯化磷的车间最高容许浓度为0.5mg/m~3。
Phosphorus trichloride by oral gavage is a moderate toxic grade, inhaled by the respiratory tract is highly toxic grade. Acute threshold concentration of rat lung macrophage damage was 686.8 mg / m ~ 3. Is a class I and strong irritant compounds. Subacute threshold concentration of 2mg / m ~ 3. It is suggested that the maximum allowable concentration of phosphorus trichloride workshop in our country is 0.5mg / m ~ 3.
