Air turns ‘moderate’ after two ‘poor’ days


Gurgaon: The city’s air improved on Friday with the air quality index being recorded in the ‘moderate’ category (164). Last two days, the index was in the ‘poor’ category. According to IMD, the wind direction has changed from northwest to southwest, leading to an improvement in the air quality.
“We are witnessing southwest wind movement in the region and this will prevail for the next two days. So, the region is not likely to witness ‘severe’ AQI this October. However, air quality may dip from the first week of November,” said meteorologist Navdeep Dahiya.
The Teri Gram station recorded an AQI of 206, at Sector 51 it was 232, 132 at Gwalpahari and 95 at Vikash Sadan on Friday, which was a significant improvement from the previous day. Gwal Pahari was recorded in 151. Teri Gram station and Sector 51 were recorded at 247 both, in Vikash Sadan the data was insufficient.
Meanwhile, as the winter season sets in, Centre for Science and Environment (CSE) has analysed air quality trends so far in Delhi-NCR. Anumita Roychowdhury, executive director, research and advocacy, CSE, said, “Delhi and the larger region will require urgent action to prevent severe smog episodes as well as speed up deeper reforms to sustain the gains. Reduce traffic volume, eliminate waste burning, eliminate dirty industrial fuels, and implement stringent dust control measures, especially in the construction sector. Act now, and act decisively.”
The analysis covers 156 continuous ambient air quality monitoring stations (CAAQMS) spread across 67 cities in Punjab, Chandigarh, Haryana, Delhi, Rajasthan, Uttar Pradesh, Bihar and West Bengal.
“This winter we may get a much severe peak in smog, as farm fire counts may get more concentrated due to the delayed effect of the rains,” said Avikal Somvanshi, programme manager at the urban data analytic lab at CSE..
