I-Sodium sulfide emanzini ihlanganisa i-H₂S encibilikisiwe, i-HS⁻, i-S²⁻, kanye ne-sulfide yensimbi encibilikisiwe etholakala ezintweni eziqinile ezilengayo, kanye ne-sulfide ezingaphili kanye ne-organic ezingahlukanisiwe. Amanzi aqukethe ama-sulfide avame ukubonakala emnyama futhi anephunga elibi, ikakhulukazi ngenxa yokukhishwa okuqhubekayo kwegesi ye-H₂S. Abantu bangathola i-hydrogen sulfide emoyeni ngamanani aphansi njengo-8 μg/m³, kuyilapho umkhawulo we-H₂S emanzini ungu-0.035 μg/L. I-Sodium sulfide.

Kunezindawo zokugcina izimpahla ze-sodium sulfide emachwebeni aseQingdao, eTianjin, naseLongkou, ezingathunyelwa ngokushesha futhi zibe nokusatshalaliswa okuzinzile emhlabeni jikelele. Chofoza lapha ukuze uthole isilinganiso esinesaphulelo.
