The present study endeavours to compare pollutant levels for summer and winter season at selected sites in Delhi, namely-Pusa in Central Delhi, ITO in East Delhi, Dwarka in South West Delhi and Rohini in North West Delhi. The 24 hour average of prevailed ambient levels of Particulate Matter (PM2.5), Nitrogen dioxide (NO2) and Nitrogen oxide (NO) air pollutants were documented. Results indicate that ambient levels of selected pollutants in winter season were significantly higher than summer season. Pollution levels were lowest in Pusa (in summer and winter) followed by Dwarka, Rohini and ITO. Crop stubble burning, crakers during festival of Diwali and adverse ambient atmospheric conditions makes the winter air worse. Effective political will, implementation of regulations, awareness amongst residents and tree-plantation could help offset winter pollution.
