Nitrogen dioxide poisoning

Nitrogen oxide poisoning is mostly caused by nitrogen oxide and nitrogen dioxide (NO2). Nitrogen dioxide is a red-brown gas, insoluble in water, and has a characteristic sweet taste. Nitrogen oxides are exposed in many occupations, including acetylene torch welding, electroplating, metal cleaning and mining, and may be exposed to nitrogen oxides during the manufacture of dyes, paints or the use of nitric acid. Nitrogen dioxide is also an important component of jet fuel and a by-product of diesel combustion. Silos of silage can also be exposed to nitrogen oxides and cause poisoning.
