Sulfur dioxide (SO2), one of the EPA criteria pollutants, is used as an indicator of all sulfur oxides in ambient air as it is the component of greatest concern and the most easily measured ( UDAQ, 2014g ). Other gaseous sulfur oxides are typically found in the atmosphere at concentrations considerably lower than sulfur dioxide ( EPA, 2014g ).

اقرأ أكثرSulfur dioxide is the only regulated air pollutant with a strong, pungent odor. Under the Clean Air Act, EPA must control 187 hazardous air pollutants, also known as toxic air pollutants or air toxics. EPA controls those chemicals for their toxicity, not for their odor. EPA requires them to be controlled at the source that generates the emissions.
اقرأ أكثرSulfur dioxide is a colorless gas with a pungent odor. It is a liquid when under pressure, and it dissolves in water very easily. Sulfur dioxide in the air comes mainly from activities such as the burning of coal and oil at power plants or from copper smelting. In nature, sulfur dioxide can be released to the air from volcanic eruptions.
