Nitrogen Dioxide (NO2): The result of nitric oxide combining with oxygen in the atmosphere; major component of photochemical smog.
Nitrogen Dioxide - NO2, is the lesser of the two emitted NOx gases from high temperature combustion in air. It is an important species in the atmosphere.
nitrogen dioxide (NO2) = a GhG
nitrous oxides (NOx) = a range of gases released during combustion and causing environmental effects including acidification and greenhouse
NMVOC = non-methane volatile organic compounds ...
NO2 (See nitrogen dioxide)
NO3 (See nitrate)

Emissions are primarily in the form of NO, which is oxidised by ozone (O3) from nitric oxide (NO) to Nitrogen dioxide (NO2). NO2) is the primary concern for effects on health, and is the species for which WHO's health-based standards are expressed.
Like the PSI, the AQI incorporates five criteria pollutants -- ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide -- into a single index. The new index also incorporates the 8-hour ozone standard and the 24-hour PM2.

Radical nitrogen-based molecules that can act to facilitate nitrosylation reactions; reactive nitrogen species include dioxidonitrogen(-) (nitrogen dioxide, nitryl radical) NO2-, ...
Nitric Oxide (NO) - precursor of ozone, NO2, and nitrate; usually emitted from combustion processes. Converted to nitrogen dioxide (NO2) in the atmosphere, it then becomes involved in the photochemical process and/or particulate formation ...
Examples include soot consisting of tiny black particles, which absorb all visible light; and nitrogen dioxide, a pollutant mostly from diesel and gasoline engines, that absorbs blue light resulting in air with a brown tint.
Air Emissions: Gas emitted into the air from industrial and chemical processes, such as ozone, carbon monoxide, nitrogen oxide, nitrogen dioxide, sulfur dioxide and others.
Nitric Oxide (NO)
A gas formed by combustion under high temperature and high pressure in an internal combustion engine; changes into nitrogen dioxide in the ambient air and contributes to photochemical smog.(1) ...
Effects may be acute from a single high-level exposure, or chronic from repeated low-level exposures to such compounds as chlorine, nitrogen dioxide, ...
Oxidising Agent is a chemical which gives up oxygen in a chemical reaction. It can also mean to take hydrogen from a substance. Oxidising agents in the air include ozone and nitrogen dioxide.
Nitrite: 1. An intermediate in the process of nitrification. 2. Nitrous oxide salts used in food preservation Nitrogen Dioxide (NO2): The result of nitric oxide combining with oxygen in the atmosphere; major component of photochemical smog.
Nitrogen Oxide (N2O) is a colourless gas with a sweet odour which is used as a weak anaesthetic ('laughing gas'). Nitrogen Dioxide (NO2) is a reddish-brown toxic gas which is one of the products of vehicle combustion and an active part of smog.
