The findings highlight the severe air pollution challenges faced by residents of New Delhi and Kolkata, particularly during winter months when thermal inversions trap pollutants near the ground. Prolonged exposure to high levels of fine particulate matter (PM2.5 and PM10) poses significant health risks, including respiratory and cardiovascular issues. Conversely, residents of coastal cities like Chennai, Bangalore, and Mumbai enjoy relatively better air quality due to natural ventilation and monsoon rains, reducing their exposure to harmful pollutants.
