The 'very poor' air quality in Delhi poses significant health risks, particularly for vulnerable groups such as children, the elderly, and individuals with pre-existing respiratory or cardiovascular conditions. Prolonged exposure to such pollution levels can lead to respiratory issues, reduced lung function, and other health complications. The moderate fog further exacerbates visibility issues, potentially increasing the risk of road accidents. Neighbouring areas like Ambala in Haryana also reported 'poor' air quality, indicating a broader regional impact.
