Ema Sulfides emantini atsandza ku hydrolysis, akhiphe i H2S emoyeni. Kuphefumula i-H2S lenyenti kungabangela kucansuka ngekushesha, kuhlanta, kuphefumula kanzima, kuphelelwa ngumoya, kanye nemiphumela leyingoti kakhulu. Kuchayeka emoyeni lonemandla langu 15–30 mg/m3 kungabangela kugula kwemehlo kanye nekulimala kwelutsandvo lwemehlo. Kuphefumula sikhatsi lesidze kwe H2S kungahlangana ne cytochrome, i-oxidase, tibopho te disulfide (-SS-) kumaprotein kanye ne amino acid, kuphazamisa tinchubo tekukhicita emaseli futsi kubangele i-hypoxia yemaseli, lokungaba yingoti ekuphileni.

Licembu ngalinye le sodium sulfide liyahlatiya tincenye kanye nekutfola kungcola kwentela kucedza ingoti yekungcola kusuka emtfonjeni. Chafata lapha kute utfole tinsita tebungcweti.
