Hydrogen sulfide (H₂S) is a colorless gas with a strong odor of rotten eggs. Exposure to hydrogen sulfide may cause irritation to the eyes and respiratory system. It can also cause apnea, coma, convulsions; dizziness, headache, weakness, irritability, insomnia; stomach upset, and if liquid: frostbite.

Public Lab: Hydrogen Sulfide Effects

Exposure to moderately higher concentrations of hydrogen sulfide can induce asthma-like symptoms and mild pulmonary disease. At higher concentrations, ~100 ppm, hydrogen sulfide can be a neurotoxin, impairing vision, motor skills, and memory. The concentration at which hydrogen sulfide is deemed immediately dangerous to life and health (IDLH) is 100 ppm (cite: AEGL, OSHA).

Hydrogen sulfide - Wikipedia

Exposure to lower concentrations can result in eye irritation, a sore throat and cough, nausea, shortness of breath, and fluid in the lungs (pulmonary edema). These effects are believed to be due to the fact that hydrogen sulfide combines with alkali present in moist surface tissues to form sodium sulfide, a caustic.
