Sulfides in water are prone to hydrolysis, releasing H₂S into the air. Inhaling large amounts of H₂S can immediately cause nausea, vomiting, difficulty breathing, suffocation, and severe toxic effects. Exposure to air concentrations of 15–30 mg/m³ may lead to conjunctivitis and damage to the optic nerve. Long-term inhalation of H₂S can interact with cytochrome, oxidase, disulfide bonds (-S-S-) in proteins and amino acids, disrupting cellular oxidation processes and causing cellular hypoxia, which can be life-threatening.

Each batch of sodium sulfide undergoes component analysis and impurity detection to eliminate the risk of impurities from the source. Click here to get professional services.
