Common air pollutants include: - Particulate Matter (PM10 and PM2.5): Tiny particles that can penetrate the respiratory system. - Nitrogen Oxides (NOx): Emitted from vehicle exhausts and industrial processes. - Sulfur Dioxide (SO2): Produced by burning fossil fuels containing sulfur. - Carbon Monoxide (CO): A colorless, odorless gas from incomplete combustion. - Volatile Organic Compounds (VOCs): Released from industrial processes and household products. - Ground-level Ozone (O3): Formed when NOx and VOCs react in sunlight.
