What Are the Main Sources of Air and Water Pollution? Air pollution refers to the contamination of the atmosphere by harmful substances such as gases, particulates, and biological molecules that pose risks to human health, ecosystems, and the environment. It results from both natural processes and human activities, altering air quality and disrupting natural atmospheric balance. Causes of Air Pollution 1.Burning Fossil Fuels Combustion of coal, oil, and natural gas in power plants, factories, and vehicles releases pollutants like carbon dioxide (CO₂), sulfur dioxide (SO₂), and nitrogen oxides (NOₓ). 2.Industrial Emissions Factories release pollutants such as particulate matter (PM), volatile organic compounds (VOCs), and heavy metals into the air during production processes. 3.Vehicle Emissions Automobiles emit carbon monoxide (CO), NOₓ, and hydrocarbons from burning fuel, contributing significantly to urban air pollution. 4.Deforestation Cutting do...
