硫化氢是一种有强烈腐败臭鸡蛋气味的无色气体,其是窒息性气体,也是刺激性气体;由于其密度大于空气,容易积聚在低洼处。在职业活动中短期内吸入较大量硫化氢气体后可引起职业性急性硫化氢中毒,表现为以中枢神经系统和呼吸系统为主的多器官损害的全身性疾病,可伴有心脏和肝脏损害。接触较高浓度硫化氢后常先出现眼和上呼吸道刺激症状,继而可出现头痛、头晕、乏力、共济失调以及轻至中度意识障碍,也可出现急性气管-支气管炎或支气管周围炎。接触高浓度硫化氢后以中毒性脑病表现 Hydrogen sulfide is a colorless gas with a strongly corrupt smell of rotten eggs, which is a smothering gas and an irritant gas. It accumulates in low-lying areas because of its density greater than air. In the short-term professional activities inhaled larger amounts of hydrogen sulfide gas can cause occupational acute hydrogen sulfide poisoning, manifested as central nervous system and respiratory system-based multiple organ damage systemic diseases, may be associated with heart and liver damage. Eye and upper respiratory tract irritation often occurs first after exposure to higher concentrations of hydrogen sulfide, followed by headache, dizziness, fatigue, ataxia, and mild to moderate disturbance of consciousness, as well as acute tracheobronchitis or bronchial inflammation. After exposure to high concentrations of hydrogen sulfide in the performance of toxic encephalopathy
