CPCB NOTICES TO NCR TOWNS ON BURSTING OF CRACKERS
Air quality still ‘very poor’, Experts say it will take a few more days for it to improve. City fared better than Delhi, Noida, Faridabad and Ghaziabad
The Central Pollution Control Board (CPCB) on Friday issued notices to authorities in NCR towns — Delhi, Gurugram, Ghaziabad and Gautam Budh Nagar — for alleged “non-compliance” of the Supreme Court’s directions regarding a ban on the sale and use of conventional firecrackers.
CPCB officials said Delhi Police commissioner Amulya Patnaik had been issued a notice directing him to file a report within a week for “not restricting” the bursting of firecrackers.
Despite the SC ban on sale and use of conventional firecrackers, widespread violation of the ban was reported on Diwali night.
GURUGRAM: Air quality in the city remained ’very poor’ on Friday, climbing to 400 on the Air Quality Index (AQI), up from 389 on Thursday.
The maximum reading of particulate matter 2.5 (PM2.5), the primary pollutant, dropped to 381ug/m3 from 622ug/m3 the previous day.
The average concentration of PM2.5 through the course of the day also showed a decline, from 399ug/m3 on Thursday to 300ug/m3, according to the Central Pollution Control Board (CPCB) data.
Kuldeep Singh, the Haryana State Pollution Control Board’s regional officer in Gurugram, said that unfavourable meteorological conditions were causing local air to “stagnate” and that the prevailing wind speeds were unable to facilitate effective dispersal of airborne particles.
“Temperature and wind, the two factors which affect air pollution, are on the lower side today,” he said, adding that it would take a few more days before the city recovers from the impact of firecrackers.
The maximum temperature
in Gurugram was recorded at 30.6 degrees Celsius, according to the India Meteorological Department, while the wind speed was lower than 1 kilometre per hour (kmph).
Since Thursday, Gurugram has also recorded a spike in the level of atmospheric carbon monoxide, benzene, nitrogen dioxide and ozone.
SK Tyagi, an assistant scientist with the CPCB’s air quality lab in Delhi, said that this could be attributed to the use of firecrackers across the city, and this indicates the formation of secondary aerosols and presence of volatile organic carbons in the atmosphere.
While these contaminants were not found to breach the safe limit set by the National Ambient Air Quality Standards, they have contributed to the rise in Friday’s AQI, Tyagi said.
However, the city seems to be faring much better than its counterparts in the National Capital Region.
On Friday, for the second day in a row after Diwali, Gurugram recorded better air quality than Delhi, Noida, Faridabad and Ghaziabad, all of which had ‘severe’ air, with AQI values crossing the 400 mark.
