Nitrogen Dioxide

October 21st, 2022, Sioux Falls, SD –

Nitrogen Dioxide (NO2) is a toxic gas comprised of nitrogen and oxygen in a group of related gases called nitrogen oxides. Nitrogen Dioxide is a red/orange, pungent, and highly reactive gas formed from the burning of fossil fuels. Examples of fossil fuels related to NO2 are coal, oil, gas, or diesel burned at high temperatures; the main source of emission is diesel-powered vehicles.

NO2 exposure concentrations are of particular concern for susceptible individuals, including asthmatics, children, and the elderly.

Effects of NO2

Nitrogen Dioxide has both human and environmental effects.

Human effects: Consist of breathing air with a high concentration of NO2 can irritate airways in the human respiratory system. Short exposure to NO2 can aggravate respiratory diseases that can lead to coughing, wheezing, and hospital admissions. Longer exposure can lead to severe respiratory problems such as lung cancer.

Environmental effects: Consists of molecules that are made of nitrogen and oxygen atoms. These nitrogen oxides contribute to the problem of air pollution such as acid rain (which harms lakes and forests), visibility/haze (which makes it more difficult to see outdoors), and nutrient pollution (which causes air and water to become polluted/contaminated).

NO2 is mainly found in diesel-powered vehicles such as cars, trucks, and buses. Other NO2 gas sources come from power plants and off-road equipment.
