Sulfide-ka biyaha ku jira ayaa u nugul hydrolysis, taasoo sii deynaysa H₂S hawada. Neefsashada xaddi badan oo H₂S ah waxay isla markiiba sababi kartaa lallabbo, matag, neefsashada oo adkaata, neef qabasho, iyo saameyn sun ah oo daran. Soo-gaadhista hawo-qaadista 15-30 mg/m³ waxay keeni kartaa conjunctivitis iyo dhaawac soo gaara neerfaha indhaha. Neefsashada muddada dheer ee H₂S waxay la falgeli kartaa cytochrome, oxidase, disulfide bonds (-SS-) ee borotiinnada iyo amino acids, taasoo carqaladeynaysa hababka oksaydhka unugyada iyo keenista hypoxia unugyada, taasoo noqon karta mid halis gelin karta nolosha.

Dufcad kasta oo ka mid ah sodium sulfide waxaa la mariyaa falanqaynta qaybaha iyo ogaanshaha wasakhda si loo baabi'iyo khatarta wasakhda ka iman karta isha. Halkan guji si aad u hesho adeegyo xirfadeed.
