Air pollution is caused by a number of different factors. Nature has amazing resources to clean the air itself. However, air pollution caused by humans is increasing to such an extent that the planet can no longer clean it completely. The air pollution we cause has long been evident in smog, acid rain and health problems caused by breathing polluted air.
Main causes of air pollution
Exhaust fumes from combustion engines. Cars, lorries, aircraft and other vehicles and machines with internal combustion engines emitexhaust gases that emit carbon monoxide and nitrogen oxide, among other things.
included. Due to the large number of combustion enginesThe smog produced in large cities causes health problems when inhaled and attacks the earth's ozone layer.
Industry. Factories, office buildings, residential buildings and power stations produce exhaust fumes that pollute the air. Fossil fuels such as oil and coal are burnt, which also cause smog. Air pollution kills plants that are important for cleaning the air and accelerates oxidation on iron. Paper mills, chemical plants, steel factories, cement and asphalt plants release exhaust gases that pollute the air.
Crude oil. Oil refineries emit hydrocarbons and particles that contribute to air pollution.
Power lines. Poorly insulated or uninsulated power lines carry high voltage, which causes air pollution.
Pesticides. Pesticides, insecticides and other chemical poisons used to kill insect pests and weeds all cause air pollution.
Radioactive fallout. Radioactive fallout distributes nuclear energy as dust particles in the air.
Fertilisers. Fine dust from artificial fertilisers for agricultural cultivation pollutes the air.
Pollution inside buildings. Sick building syndrome (SBS) is when a building is contaminated and pollutes the air we breathe. SBS occurs where there is insufficient ventilation to disperse toxic gases from carpets, dyes and cleaning products. Mould can also cause SBS.
Mining. Mining causes air pollution through the release of a large number of particles.
