Air pollution results from incomplete combustion of impure fuels.
<u>Explanation:</u>
Impure fuels are incapable of burning completely and thus result in the formation of pollutants like particulate matter 2.5 '(PM 2.5)' and particulate matter 10 '(PM 10)'.
They also release oxides of carbon and sulfur that degrade the air quality and result in its pollution.
Incomplete burning of fuels also gives out hazardous byproducts like tar and ash. These byproducts pollute both air and soil.
Air pollution results from incomplete combustion of impure fuels. Two-stroke engines emit 20% to 50% of their fuel unburned in the exhaust, but also a considerable amount of oil too. Air pollution is higher in this cases and includes a considerable amount of particulate matter.
