硫化氢 Hydrogen sulfide
（重定向自Hydrogen Sulphide）
硫化氢是无机化合物，化学式为H2S。正常是无色、易燃的酸性气体，浓度低时带恶臭，气味如臭蛋；浓度高时反而没有气味（因为高浓度的硫化氢可以麻痹嗅觉神经）。能溶于水，0 °C时1摩尔水能溶解2.6摩尔左右的硫化氢。硫化氢的水溶液叫氢硫酸，是一种弱酸；当受热时，硫化氢又从水里逸出。硫化氢是急性剧毒，吸入少量高浓度硫化氢可于短时间内致命。低浓度的硫化氢对眼、呼吸系统及中枢神经都有影响。

Hydrogen sulfide 硫化氢
（重定向自Hydrogen Sulphide）
Hydrogen sulfide is the chemical compound with the formula H
2S. It is a colorless gas with the characteristic foul odor of rotten eggs; it is heavier than air, very poisonous, corrosive, flammable, and explosive.
Hydrogen sulfide often results from the prokaryotic breakdown of organic matter in the absence of oxygen gas, such as in swamps and sewers; this process is commonly known as anaerobic digestion. H
2S also occurs in volcanic gases, natural gas, and in some sources of well water. It is also present in natural halite type rock salts, most notably in Himalayan Black Salt, which is mostly harvested from the mineral-rich Salt Range mountains of Pakistan. The human body produces small amounts of H
2S and uses it as a signaling molecule.
