PM2.5 level rises beyond safe limit in Gurgaon, Teri Gram pollution hotspot
Gurgaon: The city's air quality index (AQI) on Wednesday went up to 276 from the previous day's 260. An analysis of PM2.5 data from air quality monitoring stations over the past 10 days shows that pollution is concentrated in a few chronic pockets instead of being distributed evenly across the region. Data from Central Pollution Control Board (CPCB) indicates that Teri Gram has emerged as the city's most critical pollution hotspot so far this month, recording PM2.5 levels above 300 on six days. The station reported levels of 304 on Dec 1, 333 on Dec 2, 326 on Dec 4, 342 on Dec 6, 345 on Dec 7 and 323 on Dec 9. Sector 51 has reported consistently high baseline pollution as well, with short periods of relief. PM2.5 levels remained in the poor category for most of the first 10 days of the month, recording 283 on Dec 1, 292 on Dec 2, 251 on Dec 3, 262 on Dec 4 and 295 on Dec 5. After a brief dip to 179 on Dec 7, pollution rose again to 327 on Dec 8 and remained high at 297 on Dec 9. At Manesar's industrial belt, monitored at Sector 2 IMT, PM2.5 levels crossed 320 for four consecutive days between Dec 1 and 4, with readings of 323, 331, 327 and 302. Levels dropped slightly to 282 on Dec 6, 254 on Dec 8 and 238 on Dec 9. Vikas Sadan showed noticeable day-to-day variation rather than persistent high levels. PM2.5 levels fell to 159 on Dec 2 and 162 on Dec 9, although the area also recorded temporary spikes to 293 on Dec 4 and 290 on Dec 5. Gwal Pahari remained the least polluted among the five stations, although it too experienced seasonal smog. While there were brief spikes above 300 in early Dec, PM2.5 levels generally stayed lower than in the city's core hotspots. Lower traffic density and better air movement due to its elevation helped keep pollution comparatively lower. "The data shows that the air crisis is driven by persistent micro hotspots rather than uniform pollution across the city. With Teri Gram, Sector 51 and IMT Manesar repeatedly recording unsafe air, civic agencies need to focus on location-specific enforcement and source-wise control instead of broad city-level measures that do not address these chronic pockets," said Shubhansh Tiwari from the Centre for Science and Environment. "We have identified hotspots where pollution levels remain consistently high. Targeted enforcement drives are under way in these areas, including checks on construction dust, industrial emissions and waste burning. Strict action is being taken against violators, and monitoring is being intensified," said Krishan Kumar, regional officer, Haryana State Pollution Control Board.
