Cov Sodium sulfide hauv dej suav nrog H₂S uas yaj, HS⁻, S²⁻, nrog rau cov hlau sulfides uas yaj tau hauv cov kua qaub uas muaj nyob hauv cov khoom khov, thiab cov inorganic thiab organic sulfides uas tsis sib cais. Cov dej uas muaj sulfides feem ntau zoo li dub thiab muaj ntxhiab tsw qab, feem ntau yog vim muaj cov pa H₂S tso tawm tas li. Tib neeg tuaj yeem ntes tau hydrogen sulfide hauv huab cua ntawm qhov concentration qis li 8 μg/m³, thaum qhov txwv rau H₂S hauv dej yog 0.035 μg/L. Sodium sulfide.

Muaj cov chaw khaws khoom sodium sulfide hauv Qingdao, Tianjin, thiab Longkou chaw nres nkoj, uas tuaj yeem xa khoom tam sim ntawd thiab muaj kev faib khoom thoob ntiaj teb ruaj khov. Nyem qhov no kom tau txais tus nqi luv nqi.
