Current Air Quality Index [AQI]
Nitrogen dioxide (NO2) is an irritant gas that is a by-product of combustion. At high temperatures, airborne nitrogen and oxygen combine to form nitric oxide (NO), which transforms relatively quickly into NO2. Both of these substances, NO2 and NO, are the principal components of the family of nitrogen oxides (NOx). NO2 is responsible for the distinctive brownish colour of smog, reduces visibility and at high concentrations contributes to the formation of ozone. Chemical reactions in the atmosphere transform NO2 into nitrates (liquid or solid form).
