Understanding Air Pollution Air pollution refers to the presence of harmful substances in the atmosphere that degrade air quality and pose risks to health, ecosystems, and climate. It is a global challenge with local consequences, affecting urban and rural environments alike. As on 2025, the following are the list of challenges and methods to minimize the pollution levels and development of the action plan for the CHANGE Major Pollutants in the Atmosphere Particulate Matter (PM2.5 & PM10) – Tiny particles that penetrate lungs and bloodstream. Nitrogen Oxides (NOx) – Emitted from vehicles and industrial processes. Sulfur Dioxide (SO₂) – From burning fossil fuels and smelting. Carbon Monoxide (CO) – Incomplete combustion of fuels. Ground-Level Ozone (O₃) – Formed by chemical reactions between NOx and VOCs. Volatile Organic Compounds (VOCs) – From solvents, paints, and fuels. Greenhouse Gases (CO₂, CH₄) – Contribute to climate change. Methods to Minimize Air Pollution ...

Air pollution refers to the presence of harmful substances in the air, including gases, particulate matter, and biological molecules, that pose risks to human health, the environment, and the climate. These pollutants may come from various sources, both natural and man-made. Key Pollutants: Carbon Dioxide (CO2): A greenhouse gas emitted from burning fossil fuels (e.g., coal, oil, and gas), deforestation, and various industrial processes. Carbon Monoxide (CO): A colorless, odorless gas produced by the incomplete combustion of fossil fuels. Chlorofluorocarbons (CFCs): Chemicals used in refrigerants and aerosol propellants, responsible for ozone depletion. Nitrogen Oxides (NOx): Produced from vehicle emissions, industrial activities, and power plants, contributing to smog and acid rain. Sulfur Oxides (SOx): Emitted from burning coal and oil, leading to acid rain and respiratory problems. Methane (CH4): A potent greenhouse gas released from agriculture, livestock, and landfills. 2.
