Workers are primarily exposed to hydrogen sulfide by breathing it. the effects depend on how much hydrogen sulfide you breathe and for how long. exposure to very high concentrations can quickly lead to death. short term (also called acute) symptoms and effects are shown below: worker exposure limits. niosh rel (10 min. ceiling): 10 ppm.
