There is the potential for widespread occupational exposure to H2S, including in the oil and water treatment industries.

متن کاملHydrogen sulfide exposure in an adult male
Hydrogen sulfide (H(2)S) is responsible for many incidents of occupational toxic exposure, especially in the petroleum industry. The clinical effects of H(2)S depend on its concentration and the duration of exposure. H(2)S is immediately fatal when concentrations are over 500-1000 parts per million (ppm) but exposure to lower concentrations, such as 10-500 ppm, can cause various respiratory sym...
