LIUHUAQINGDUIRENDESHENGLIFANYING 1、硫化氫的侵入表現為粘膜吸收快,皮膚吸收少，其毒作用的主要靶器是中樞神經系統和呼吸系統，對毒作用最敏感的組織是腦和粘膜接觸部位。接觸高濃度（1000mg/m3以上)硫化氫后數秒或數十秒鐘內突然昏迷、抽搐，呼吸、心跳驟停，發生“電擊樣”死亡。 2、因硫化氫比空氣重，所以能在低洼地區聚集，在低濃度下，通過硫化氫的氣味特性能檢測到它的存在，但不能依靠氣味來警示危險濃度，因為處于高濃度［超過150mg/m3］的硫化氫環境中，人會由于嗅覺神經受到麻痹而快速失去嗅覺，過多暴露于硫化氫中能毒害呼吸系統的細胞，導致死亡。如血液中存在酒精能加劇硫化氫的毒性，即使在低濃度［15mg/m3～75mg/m3］時，硫化氫也會刺激眼睛和呼吸道。
