PM2.5 refers to fine particulate matter with a diameter of less than 2.5 micrometres. It poses significant health risks. These particles can penetrate deep into the lungs and enter the bloodstream. Sources include vehicle emissions, industrial discharges, and biomass burning. In India, PM2.5 levels often exceed safe limits. This pollution affects air quality and public health. Awareness and action are crucial for improvement.
