ASTM D1607 - 91(2011) standard test method for nitrogen dioxide content of the atmosphere (griess-saltzman reaction)
Nitrogen dioxide plays an important role in photochemical smog-forming reactions and, in sufficient concentrations, is deleterious to health, agriculture, materials, and visibility. In combustion processes, significant amounts of nitric oxide (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 ...

ASTM D3608 - 95(2011) standard test method for nitrogen oxides (combined) content in the atmosphere by the griess-saltzman reaction
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. 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. ...
