The severe air pollution in Delhi poses significant health risks, particularly for vulnerable groups such as children, the elderly, and those with pre-existing respiratory conditions. The high AQI levels can lead to respiratory issues, eye irritation, and other health complications. The situation is further exacerbated by the expected use of firecrackers during Diwali, which could worsen air quality and increase the risk of health problems for residents. The pollution also highlights the broader environmental challenges faced by northern India during the winter months.
