Say sodium sulfide ed danum et kaiba so tinunaw ya H₂S, HS⁻, S2⁻, ontan met ed acid-soluble metal sulfides ya walad saray suspended solids, tan saray undissociated inorganic tan organic sulfides. Say danum ya walay sulfides to et mabetbet ya ompatnag ya andeket tan walay makapasinagem ya angob to, lapud tuloytuloy ya ipapaway na H2S gas. Nayarin nanengneng na totoo so hydrogen sulfide ed dagem no 8 μg/m3 so konsentrasyon to, bangbalet say threshold na H2S ed danum et 0.035 μg/L. Sodium sulfide.

Wala ray bodega na sodium sulfide ed saray pantalan na Qingdao, Tianjin, tan Longkou, ya nayarin ipawit a tampol tan walaan na malet ya distribusyon ed interon mundo. Pindoten dia pian makala na diskwento.
