NO 2 is just one component of air pollution, which is made up of many pollutants (including particulate matter, ozone, carbon monoxide), which are known to have numerous adverse effects on health. NO 2 is a pollutant formed mainly from fossil fuel combustion, and traffic emissions can contribute up to 80% of ambient NO 2 in cities.
