With an aim to bring down the pollution levels in Delhi, the Delhi government on Saturday has written to the neighbouring states—Uttar Pradesh, Haryana, Rajasthan and Punjab— asking them to take all precautionary measures to reduce crop burning. "The detailed analysis of ambient air quality data shows that Particulate matter like PM2.5 and PM 1, gaseous pollutants like NO2. CO, secondary pollutant like NH3 show an increasing trend in the month of October, November, which coincide with agricultural/ crop burning in neighbouring states," Hussain said in his letter. The Central Pollution Control Board (CPCB) and the State Pollution Control Boards (SPCBs) monitor ambient air quality in the country under the National Air Quality Monitoring Programme (NAMP). The National Green Tribunal (NGT) and Delhi High Court have also from time to time directed the neighbouring states for submitting the action plan to prevent air pollution emanating from crop stubble burning after the harvesting season.
