Delhi’s AQI ‘very poor’ for third day in a row, no respite for next six days
Delhi, for the third consecutive day, recorded air quality in the ‘very poor’ category, making it the most polluted city in the country on Wednesday. It reported a 24-hour average Air Quality Index (AQI) of 364 – up from Tuesday’s AQI of 327. The Indian Institute of Tropical Meteorology (IITM) forecast the AQI to be in the ‘very poor’ and ‘severe’ categories for the next six days. “Meteorological conditions are unfavourable for the effective dispersion of pollutants as calm winds prevail during (Tuesday) night,” it added. According to the Indian Agricultural Research Institute data, Wednesday saw 57 cases of stubble burning in Punjab, 15 in Haryana, 68 in Uttar Pradesh and none in Delhi. Since September 15, 1,638 cases of stubble burning have been reported in Punjab and 680 in Haryana, which is the lowest when compared to the same period since 2020, IARI data showed. Meanwhile, 808 cases of stubble burning were reported in Uttar Pradesh and 11 in Delhi – the highest so far since 2020 during this period. According to the Decision Support System for Air Quality Management in Delhi, 8% of the pollutants on Tuesday were the result of stubble burning. The data on Wednesday showed that the contribution of road dust and construction activities was around 3%. The transport sector remained the highest contributor at 13.5%. Anumita Roychowdhury, Executive Director of Research and Advocacy at the Centre for Science and Environment said, “Spike in pollution even with low stubble burning shows the increasing impact of local and regional sources of pollutants in Delhi-NCR. With this being the festival season, the major cause of pollution is vehicle emissions due to traffic congestion.”
