NIOSH 6004 (Issue 2)

SULFUR DIOXIDE

This test method uses a ion chromatography to measure sulfuric acid, sulfate salts, and sulfite salts are collected on the front filter and may be quantitated as total particulate sulfate. Sulfur dioxide is a toxic gas with a pungent, irritating smell. It is released naturally by volcanic activity and is produced as a by-product of the burning of fossil fuels contaminated with sulfur compounds.
