The deteriorating air quality in Delhi NCR poses significant health risks, particularly for vulnerable groups such as children, the elderly, and those with pre-existing respiratory conditions. The 'poor' AQI level can lead to breathing difficulties and aggravate lung and heart diseases. The situation may worsen if GRAP Stage 2 or Stage 3 measures are invoked, potentially leading to stricter restrictions on vehicular movement and industrial activities. The ongoing stubble burning in Punjab and Haryana remains a critical issue, contributing to the region's air pollution and impacting public health.
