Question

list the various causes of air pollution​

Answer 1

Causes of air pollution -:

• Industrial plants, factories, and power plants release high amounts of organic compounds, chemicals, particulate matter, and carbon monoxide into the air.
• fossil fuel combustion is the biggest contributor to air pollution. The leading culprit today is traffic, but factories and power plants also continue to contribute to some extent. Conventional power plants that com-bust fossil fuels to produce energy emits hazardous gases such as oxides of nitrogen, Carbon Monoxide, etc.
• Use of household and farming chemicals produce like Dusting of crops, painting supplies, home fumigation, household cleaning products, fertilizer powder, insect/pets sprays, hair sprays, and deodorant sprays release harmful chemicals into the air, causing pollution.
• Natural events can as well cause air pollution. However, they are rarely witnessed, and some of them are very disastrous and difficult to prevent from happening. Examples of natural events that lead to air pollution include volcanic eruptions, whirlwinds, forest fires, and gaseous releases from decaying plants and animals or radioactive decay of rocks.
• The majority of developing countries burn charcoal, wood, and crop waste to produce fuel used for cooking and heating. As such, the traditional practice of wood and charcoal burning is usually a chief contributor to indoor air pollution in developing nations. Burning charcoal, wood, and crop waste release Carbon Monoxide (CO), Carbon Dioxide (CO2), and particulate matter into the atmosphere that potentially causes air pollution.
• In some regions, waste is incinerated instead of being land-filled or recycled and as such, it substantially contributes to air pollution. Some agricultural practices like burning agricultural land after harvest also contributes in air pollution.

Hope this helps.

Answer 2

Burning of Fossil Fuels: Sulfur dioxide emitted from the combustion of fossil fuels like coal, petroleum and other factory combustibles are one of the major cause of air pollution. Pollutants emitted from vehicles further contribute to the degradation of the environment. Carbon Monoxide produced by the incomplete combustion of fuel is another major pollutant along with the Nitrogen Oxides, that are produced from both natural and man-made processes.

Agricultural Activities: Ammonia is a very common byproduct of the agriculture-related activities and is one of the most hazardous gases in the atmosphere. The use of insecticides, pesticides and fertilizers in agriculture also leads to the emission of harmful chemicals causing pollution.

Exhaust from Factories and Industries: Manufacturing industries and petroleum refineries release a large amount of carbon monoxide, hydrocarbons, organic compounds and chemicals into the air thereby depleting the quality of air.

Mining Operations: During the process of mining, huge volumes of dust and other chemicals are released into the air causing massive air pollution and leading to deteriorating health conditions of mining workers and nearby residents.

Indoor Air Pollution: Household cleaning products, painting supplies etc. emit toxic chemicals in the air while causing air pollution
