Answer:
Troposphere
is the lowest region of the atmosphere, i.e., closest to the earth. It
extends roughly to a height of about 11 km. It contains mainly nitrogen and
oxygen. It also contains argon, carbon dioxide, water vapours, aerosols and
traces of many other gases. The pollution of troposphere occurs due to the
presence of undesirable gases and particulates. The main pollutant gases are:
(i) Oxides of carbon (CO and\[C{{O}_{2}}\]) -CO is a major pollutant.
(ii) Oxides of sulphur (\[S{{O}_{2}}\]and \[S{{O}_{3}}\])
(iii) Oxides of nitrogen (NO and \[N{{O}_{2}}\])
(iv) Hydrocarbons
(v) Hydrogen sulphide\[({{H}_{2}}S)\], etc.
The particulate pollutants include dust, mist, fumes, smoke
and aerosols.
