对健康的危害:五硫化二磷遇空气释放出硫化氢气体(空气具有一定的湿度,湿度越大,释放的硫化氢的浓度越大)。当硫化氢的浓度为0.015%,会令人感到难受、头痛、胸部有受压感,疲倦;当浓度为0.02%,5～8min以后,眼、鼻、咽喉的粘膜感到灼热性疼痛;当达到0.05%,在15～30min内引起眼睑受刺激、难受、呕吐、咳嗽、眩晕、出冷汗、腹泻、呼吸困难、心跳、头痛、疲倦、神志不清等症状,如更长时间停留时,就会产生支气管炎及肺炎。硫化氢危害更为严重的是非常可怕的脑肿胀,同时有严重的后遗症,中毒后往往遗留下连续数年的头痛、发烧、难受、智力欠佳、痴呆脑膜炎、肺炎等,除此之外,严重的还并发心脏循
Health hazards: Phosphorus pentasulfide releases hydrogen sulfide gas in the air (the air has a certain humidity, the greater the humidity, the greater the concentration of hydrogen sulfide released). When the concentration of hydrogen sulfide is 0.015%, people will feel uncomfortable, headache, chest pressure and fatigue; when the concentration of 0.02%, 5 ~ 8min later, eye, nose and throat mucosa feel burning pain; when reached 0.05%, causing eyelid irritation, discomfort, vomiting, coughing, dizziness, cold and sweat, diarrhea, dyspnea, heartbeat, headache, tiredness and delirium during 15 ~ 30min Bronchitis and pneumonia. Hydrogen sulfide is more serious harm is very terrible brain swelling, and severe sequelae, poisoning often left behind for several consecutive years of headache, fever, discomfort, mental retardation, meningitis, pneumonia, etc., in addition Serious also complicated by cardiac circulation
