Gurgaon: The city's air quality showed minor improvement on Tuesday, but pollution levels remained on the higher end of the ‘poor' category, with a 24-hour average AQI of 298, down from Monday's 310. Experts warn that relief is unlikely, as calm winds and low temperatures are expected to trap pollutants near the ground, preventing improvement in air quality in the coming days.
Monitoring stations across the city reflect the persistent pollution. Gwalpahari recorded an AQI of 361, and Vikas Sadan registered 314, both in the ‘very poor' category. Sector 51 and Teri Gram stations showed readings of 276 and 294, respectively, categorized as 'poor' but close to elevated pollution levels.
According to the System of Air Quality and Weather Forecasting and Research (SAFAR), air quality will likely remain ‘very poor' to ‘severe' over the next six days. Surface winds are expected to vary, with speeds under 4 kmph in the morning, rising to 6-8 kmph in the afternoon, offering slight ventilation improvement. Mornings are likely to stay misty, though afternoons may be clear. "Meteorological conditions are expected to severely inhibit pollutant dispersion," according to SAFAR.
Local sources, including garbage burning, road dust, and vehicle emissions, contribute significantly to pollution, as low wind speeds hinder pollutant dispersal, says independent air quality expert Sachin Panwar. He added "Afternoon warmth helps ventilate pollutants, but moisture in the air at night traps them, especially during mornings. Though stubble burning continues in Lahore, Punjab, and Haryana, its impact here has been limited by inconsistent north-westerly winds. However, stronger north-westerlies expected around Nov 7 could worsen conditions as more pollutants drift into NCR."
Dr Sarika Verma, an ENT specialist, advises residents to limit outdoor activities during peak pollution hours, particularly for children, the elderly, and individuals with respiratory issues like asthma or bronchitis. "With rising pollution, respiratory infections are increasing. Extended outdoor exposure can lead to complications, and we recommend N95 masks if outdoor activity is necessary," she said.
Tuesday's maximum temperature was 31.9 degrees Celsius, up from Monday's 31.3 degrees, while the minimum rose slightly to 16.2 degrees. According to the IMD, no major change in temperature is expected over the coming days.
