Hydrogen Sulfide (H2S) monitoring
Hydrogen sulfide is also created through industrial processes and released into the atmosphere. The main sources of anthropogenic Hydrogen sulfide (H2S) emissions are from petroleum refineries, paper mills, coke ovens (aluminum, steel, graphite, electrical, and construction industries) and to a smaller extent tannaries.
Hydrogen sulfide is toxic to many different parts of the human body, it effects the nervous system most acutely and also inhibits respiration. General harmful levels of Hydrogen sulfide (H2S) exposure are 5-10 ppm, levels above this begin with eye irritation and lead up to death.
