When the atmosphere is contaminated by pollutants from both human and natural sources, it is called air pollution. Air pollution can encompass a variety of pollutants such as dust, smoke, harmful gases, and toxic chemicals that are released into the air from human activities and natural processes. Human-induced sources include industrial emissions, vehicle exhaust, power generation, deforestation, and other activities that release gases and particles into the atmosphere. Natural sources include volcanic eruptions, forest fires, and dust storms. Air pollution has detrimental effects on human health, ecosystems, and the overall environment, emphasizing the need for monitoring and control measures to reduce its impact.
