The deteriorating air quality poses significant health risks, particularly for vulnerable groups such as children, the elderly, and those with respiratory conditions. Visibility has been reduced due to dense fog and smog, potentially affecting road and air travel. The restrictions under GRAP-3 aim to mitigate further pollution but may disrupt daily activities, including commuting and construction work. Public health concerns are heightened as the AQI in several areas has reached 'severe' levels, with IIT Delhi recording the highest AQI at 442.
