Nitrogen dioxide Data

Nitrogen dioxide (NO2) is a gas that is harmful to human health (United States Environmental Protection Agency (US EPA), 2021), ecosystems, and plants (US EPA, 2008). It can be emitted directly into the air but is often formed as a secondary pollutant when nitric oxide (NO) emissions react with other chemicals. It also contributes to the formation of secondary particulate matter (PM) and ozone, which have their own health impacts. In New Zealand, motor vehicles are the main human-made source of nitrogen oxides (NOx) the collective term for NO2 and NO.

Human exposure to high nitrogen dioxide concentrations causes inflammation of the airways and respiratory problems and can trigger asthma attacks. Nitrogen dioxide can cause leaf injury in plants exposed to high levels. It also contributes to forming secondary particulate matter and ozone, which have their own health impacts.

Nitrogen dioxide is a gas primarily formed through burning fossil fuels, mainly by motor vehicles (particularly diesel), but also from industrial emissions. Because nitrogen dioxide concentrations are closely associated with vehicle emissions, it can be used as a proxy for other motor-vehicle pollutants such as benzene, carbon dioxide, and carbon monoxide.

This dataset reports on the annual trends assessed for the period 2011-2020.

Nitrogen dioxide (NO2) is a gas. It can be emitted directly into the air but is most often formed when nitric oxide (NO) emissions react with other chemicals in the air. Nationally, road motor vehicles are the main human-made source of nitrogen oxides (NOx, the collective term for NO2 and NO). NO2 may cause respiratory infections and reduced lung development and functioning.

Nitrogen dioxide (NO2) and nitric oxide (NO) (collectively known as nitrogen oxides, NOx) are emitted from the combustion of fossil fuels and from natural sources such as volcanoes. The four main human-made sources of key pollutants in New Zealand are burning wood or coal for home heating, road motor vehicle use, industry, and household outdoor burning.
