Hydrogen sulfide (H2S)

Hydrogen sulfide is one of the most common toxic air pollutants. Hydrogen sulfide is recognizable by its distinctive rotten egg odor. Hydrogen sulfide, H2S, is formed by the breakdown of organic materials and is typically found near agricultural locations, waste treatment plants and industrial sites. Many sources of hydrogen sulfide exist: intensive swine operations, paper and pulp mills, asphalt plants, slaughterhouses and rendering plants, municipal waste landfills, and sewage treatment plants.
