Standard Test Method for Nitrogen Oxides (Combined) Content in the Atmosphere by the Griess-Saltzman Reaction

Importancia y uso:

5.1 Both NO₂ and NO play an important role in photochemical-smog-forming reactions. In sufficient concentrations NO₂ is deleterious to health, agriculture, materials, and visibility.

5.2 In combustion processes, significant amounts of NO may be produced by combination of atmospheric nitrogen and oxygen; at ambient temperatures, NO can be converted to NO₂ by oxygen and other atmospheric oxidants. Nitrogen dioxide also may be generated from processes involving nitric acid, nitrates, the use of explosives, and welding.
