Gurugram: The city’s air quality index (AQI) on Tuesday was at the low end of ‘poor’ at 217, slightly better than Monday’s 230, due to wind speed and fewer farm fires.
Currently, the wind speed is around 10kmph to 18kmph, which has helped spread the pollution, experts said. It is likely to dip to 4kmph to 8kmph on Friday, which will make dispersal difficult and may worsen air quality thereafter, they said.

Moreover, paddy burning emissions contributed 3% to PM2.5 in Delhi-NCR on Tuesday, compared to 13% the previous day. The AQI was ‘moderate’ in Vikas Sadan (182) and Sector 51 (200), while Teri village (265) recorded ‘poor’ air on Tuesday. Data not available at Goalpahari station. November has so far witnessed six ‘poor’ and ‘very poor’ days each, two ‘severe’ days and one ‘moderate’ day.
“The air quality index is likely to remain ‘poor’ till Thursday as high levels of air are favorable for dispersion of pollutants. But after Friday, AQI is likely to remain in the low end of ‘very poor’ due to drop in temperature and moderate mixing level elevation,” said Subhansh.

Satellites detected fires in 141 farms in Punjab, 21 in Haryana and 84 in Uttar Pradesh, according to the Indian Agricultural Research Institute. Haryana recorded 3,149 farms between September 15 and November 15, with the highest number in Fatehabad (689), Kaithal (628), Jind (442), Kurukshetra (298) followed by Karnal (280) and Ambala (214). Logged in. ), according to satellite data collected by NASA and collected by the Indian Agricultural Research Institute. Meanwhile, in Punjab, 45,464 farms have caught fire during this period.
Meanwhile, Delhi’s air quality improved to the lower end of the ‘poor’ category. Overall AQI was 227 against 294 on Monday. Air quality is likely to remain in the ‘poor’ category at least till Thursday.
According to the guidelines issued by the Central Pollution Control Board, when the AQI is in the ‘poor’ zone, most people may experience respiratory distress on prolonged exposure. An AQI between zero and 50 is considered ‘good’, 51 and 100 ‘satisfactory’, 101 and 200 ‘moderate’, 201 and 300 ‘poor’, 301 and 400 ‘very poor’ and 401 and 500 ‘severe’.
Currently, Phase 2 of Graded Response Action Plan (GRAP) has been implemented across Delhi-NCR. GRAP has classified Delhi under four levels of adverse air quality, which is reflected through the AQI. Stage 1 is applied when the AQI is ‘poor’ (AQI 201-300), stage 2 when it is ‘very bad’ (AQI 301-400), stage 3 when the air is ‘severe’ (AQI 401-450) and stage 4. When it is ‘Severe+’ (AQI >450). Actions under Phases 2, 3 and 4 should be invoked at least three days before the AQI reaches the projected level for that phase.
