毒理学数据:
1、 急性毒性:小鼠腹腔LD50:1490 mg/kg;兔经皮LD50:11300 mg/kg ;大鼠经口LD50:20g/kg; 大鼠吸入LC50:19689mg/m3,4小时;
2、对眼睛、呼吸系统及皮肤有刺激性,接触皮肤引起过敏。
3.急性毒性
LD50:16g/kg(大鼠经口);1490mg/kg(小鼠腹腔);11300mg/kg(兔经皮)
LC50:19689mg/m3 ppm(大鼠吸入,4h)
4.刺激性 家兔经皮:500ul,轻度刺激。
5.亚急性与慢性毒性 大鼠经口5%LD50,4~6个月(喂饲),中度蓄积。
生态学数据:
1.生态毒性 EC50:37~55mg/L(5,15,30min)(发光菌,Microtox测试)
