GURUGRAM: Air air pollution degree crossed the 'critical' mark on Sunday morning, with PM2.5 recording a prime of 366.37 micrograms according to cubic metre (g/m3). By evening despite the fact that, enough sunlight and ensuing fall in moisture degree in the decrease environment had pushed PM2.5 down to 269.88 g/m3, considered 'very deficient'.

"The concentration of particulate matter increases in the morning due to fog and low temperature. Thankfully, the concentration decreased by evening, as better sunlight helped lowering moisture in the atmosphere," said an reliable of Haryana State Pollution Control Board. The highest PM2.5 degree recorded on Saturday was 288 g/m3 ('very deficient') and on Friday was 216 g/m3.
While air high quality index (AQI) for Sunday was unavailable, on Saturday and Friday, it was 366 and 373 respectively.
Officials of the meteorological division blamed the prime air pollution on snowfall in mountainous areas. "Due to snowfall in mountainous areas, north India continues to reel under a cold wave. Temperature is expected to go down further in Delhi-NCR over the next week. Fog is also expected to engulf the region in the mornings," said the met reliable.
An reliable of HSPCB said the graded response action plan (GRAP) for 'very deficient' is already in position, and if the air pollution degree hit and remain 'critical' over the following 48 hours, GRAP for that degree might be carried out. "We've implemented all GRAP measures for the 'very poor' category. We've instructed all concerned civic agencies and departments to take necessary action. However, the 'severe' measures will be implemented only if PM2.5 remains above 250 g/m3 for 48 hours," he said.
Experts continue to blame construction process and garbage burning for the situation.
"We can't just blame fog for increase in particulate matter. We're still witnessing cases of waste burning and dust pollution near construction sites. There is an urgent need to check both," said Debjani Ghosh, an environmental engineer.
The minimum and maximum temperature on Sunday was between 7°C and 22°C, respectively.
