Nitrogen oxides refer to compounds composed solely of nitrogen and oxygen elements. They encompass various compounds including nitrous oxide (N₂O), nitric oxide (NO), nitrogen dioxide (NO₂), dinitrogen trioxide (N₂O₃), dinitrogen tetroxide (N₂O₄), and dinitrogen pentoxide (N₂O₅). In occupational environments, exposure often involves several gas mixtures collectively referred to as "nitrogen oxides" or "nitrogen dioxide" (NO₂). Nitrogen oxides exhibit varying degrees of toxicity.
After fixation, nitrogen oxides can be transformed into ammonia gas, which plays a significant role in industries like fertilizers.
