What is 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. C
