new so2 Measurement For determining the quality

Methods for Determining Parent Compounds and Degradation Products in Environmental Media. Methods are available for measuring sulfur dioxide in air (EPA 1995k; NIOSH 1994a; WHO 1979). One difficulty in measuring environmental levels of sulfur dioxide is the interference from other air pollutants, in particular, other sulfur-containing compounds.

    EPA’s national ambient air quality standards for SO 2 are designed to protect against exposure to the entire group of sulfur oxides (SO x ). SO 2 is the component of greatest concern and is used as the indicator for the larger group of gaseous sulfur oxides (SO x ). Other gaseous SO x (such as SO 3) are found in the atmosphere at concentrations much lower than SO 2 .
