The pollution crisis in Delhi poses severe health risks, particularly respiratory issues, due to high PM2.5 concentrations. The winter season's low wind speeds and high humidity trap pollutants, intensifying the problem. Agricultural burning in neighbouring states contributes significantly to Delhi's air quality deterioration, with smoke travelling across state boundaries. The Commission for Air Quality Management estimates that secondary particulate formation, transport emissions, biomass burning, dust, and industrial activity collectively account for the majority of winter pollution in Delhi-NCR.
