He maʻalahi nā sulfide i loko o ka wai i ka hydrolysis, e hoʻokuʻu ana i ka H₂S i ka lewa. ʻO ka hanu ʻana i ka nui o ka H₂S hiki ke hoʻoulu koke i ka nausea, ka luaʻi ʻana, ka paʻakikī o ka hanu ʻana, ka hanu ʻana, a me nā hopena ʻawahia nui. ʻO ka ʻike ʻana i nā nui o ka ea o 15-30 mg/m³ e alakaʻi i ka conjunctivitis a me ka hōʻino ʻana i ke aʻalolo optic. ʻO ka hanu lōʻihi ʻana o ka H₂S hiki ke launa pū me ka cytochrome, oxidase, disulfide bond (-SS-) i loko o nā protein a me nā waikawa amino, e hoʻopilikia ana i nā kaʻina hana oxidation cellular a me ke kumu o ka hypoxia cellular, hiki ke hoʻoweliweli i ke ola.
