Mā te hongi nui i te H₂S ka puta tonu te whakapairuaki, te ruaki, te uaua ki te manawa, te whakamomori, me ngā pānga kino kino. Mā te pānga ki ngā kukū hau o te 15–30 mg/m³ ka arahi pea ki te conjunctivitis me te kino ki te io whatu. Mā te hongi roa i te H₂S ka taunekeneke ki ngā here cytochrome, oxidase, disulfide (-SS-) i roto i ngā pūmua me ngā waikawa amino, ka whakararuraru i ngā tukanga waikura pūtau me te puta te hypoxia pūtau, ka tūpono ai te ora.

Ka tātarihia ngā wāhanga me te kitea ngā poke i ia puranga o te konutai whanariki hei whakakore i te mōrearea o ngā poke mai i te pūtake. Pāwhiri ki konei hei tiki ratonga ngaio.
