毒理学数据:
1、小鼠、大鼠吸入LC50:634×10-6/1h、712×10-6/1h;大鼠吸入LC50:444×10-6/4h。 硫化氢主要经呼吸道吸收,人吸入(70~150mg/m3)/(1~2h),出现呼吸道及眼刺激症状, 硫化氢可以麻痹嗅觉神经,吸2~5min后不再闻到臭气。吸入(300mg/m3)/1h,6~8min出现眼急性刺激症状,稍长时间接触引起肺水肿。吸入硫化氢能引起中枢神经系统的抑制,有时由于刺激作用和呼吸的麻痹而导致最终死亡。 在高浓硫化氢中几秒内就会发生虚脱、休克,能导致呼吸道发炎、肺水肿,并伴有头痛、胸部痛及呼吸困难。硫化氢贮存区附近不应有氧化可燃材料、酸或其他腐蚀性材料。避免暴露于高温环境。
2.急性毒性 LC50:618mg/m3(444ppm)(大鼠吸入)
3.刺激性 暂无资料
4.亚急性与慢性毒性 家兔吸入0.01mg/L,每天2h,3个月,引起中枢神经系统的机能改变,气管、支气管黏膜刺激症状,大脑皮层出现病理改变。小鼠长期接触低浓度硫化氢,有小气道损害。
5.其他LCLo:600ppm(人吸入30min)
生态学数据:
1.生态毒性
TLm:0.0071~0.55mg/L(96h)(黑头呆鱼);0.0448~0.0478mg/L(96h)(蓝鳃太阳鱼)
2.生物降解性 暂无资料
3.非生物降解性 暂无资料
4.其他有害作用 该物质对环境有危害,应注意对空气和水体的污染。
