Explain tropsopheric pollution in 100 words .

Explanation

The increase in the concentration of undesired gases and particulate matter in the troposphere to such an extent that they can produce undesirable effects on human beings and their environment is called tropospheric or air pollution. The tropospheric pollution is due to following two types of pollutants :
(i) Gaseous pollutants, e.g., oxides of sulphur `(SO_(2), SO_(3))`, oxides of nitrogen `(NO, NO_(2))`, oxides of carbon `(CO, CO_(2))`, hydrogen sulphide, hydrocarbons, aldehydes, ketones, etc.
(ii) Particulate matter, e.g., mists, smoke, fumes, dust, carbon particles, lead and cadmium compounds, bacteria, fungi, moulds, etc.
It is caused by combustion of fuel, industrial processes, use of pesticides, toxic substances, etc. It can be controlled by avoiding use of fossil fuels, by cleaning automobile exhaust gases, use of cyclone collector, proper waste management, etc.
