The extensive use of fireworks during Diwali has led to a sharp decline in air quality, particularly in urban areas like Delhi. The toxic fumes, containing sulphur and other harmful chemicals, pose significant health risks, including respiratory issues and aggravated conditions for individuals with pre-existing health problems. The situation is further exacerbated by other pollution sources, such as vehicular emissions and crop stubble burning. The deteriorating air quality has made it challenging for residents to breathe, with prolonged exposure potentially leading to long-term health complications.
