Following A hole of two years, Punjab recorded an ‘exceptionally poor’ Air Quality Index (AQI) on Diwali night (November 14) when contrasted with a similar period in 2019 and 2018, when its AQI was ‘poor’. On Saturday, AQI was ‘poor’ during the day, yet early Sunday, six of Punjab’s significant urban communities fell under the ‘exceptionally poor’ classification of AQI, with Amritsar beating the diagram, trailed by Ludhiana and Patiala. Many less stubble consuming cases were recorded by satellite this Diwali, however, the significant explanation behind that was the overcast climate in different pieces of the state.
This year, as indicated by ongoing information gave by the Punjab Pollution Control Board (PPCB) of the Continuous Ambient Air Quality Monitoring Stations set up at Amritsar, Jalandhar, Ludhiana, Khanna, Mandi Gobindgarh, Patiala, Bathinda, and Ropar, the normal AQI of Punjab was 328 (exceptionally poor) against 293 (poor) a year ago. It was 234 (poor) in 2018, and 328 (extremely poor) in 2017.
AQI zones are arranged according to the presence of particulate issue per cubic meter noticeable all around — 0-50 (great), 51-100 (good), 101-200 (moderate), 201-300 (poor), 301-400 (exceptionally poor) and 401-500 (serious).
According to information, the base PM10 in the earlier year was 90 micrograms for each cubic meter (ug/m3), and PM2.5 was 43 ug/m3, though this year, these are 118 ugs/m3 and 90 ug/m3, separately which is 31 percent and 109 percent expansion individually, more when contrasted with a year ago. Both PM10 and PM2.5 were under the ‘modestly contaminated classification’ according to quality zones classes.
In any case, AQI estimation of Mandi Gobindgarh declined from 311, which was second most elevated after Patiala in 2019, to 262 this year. At 4 pm, it was recorded at 281.
“The high estimation of AQI could be because of contrast in the air conditions (low temperature i.e decline of 19 percent (23°C in 2019 to 19°C in 2020) winning during the season, bringing about diminished scattering of the poisons,” said Krunesh Garg, part secretary, PPCB.
According to Central Pollution Control Board (CPCB) information, the AQI of Punjab’s urban areas on Diwali day at 4 pm was ‘poor’ in most of Punjab’s urban areas notwithstanding Amritsar and Bathinda where it was recorded ‘exceptionally poor’ with 313 and 322 AQI levels, separately.
However, according to the continuous information gathered by PPCB from 7 pm on Saturday to 6 am November 15, the AQI of all significant urban areas entered low quality incorporating Amritsar with 386, Ludhiana 376, Patiala 334, and Jalandhar 328. Just Khanna and Mandi Gobindgarh were under a ‘poor’ zone with 281 and 262 AQI, individually.
As indicated by CPCB, Bathinda’s AQI was at 354 at 4 pm on Sunday.
Despite the fact that blasting saltines was permitted between 8 pm to 10 pm on Diwali night, wafers were blasted till late 12 PM and in any event, during the day on Sunday.
There is an extensive improvement in Chandigarh’s AQI, which was 145 on Sunday morning when contrasted with 267 on Diwali night a year ago.
PPCB sources said that in the wake of praising such a green Diwali for a very long time, Punjab again depended on blasting wafers without any potential repercussions this time.
Sources said only 352 stubble consuming cases were recorded this time on Diwali day against 2,231 fire occurrences detailed a year ago. On Sunday, just 96 stubble consuming cases could be recorded. “There were thick mists on Diwali in different pieces of the state and on Sunday, it was all shady till late evening, trailed by a downpour, so setting fields ablaze was impractical in the downpour,” said PPCB sources.
In Punjab, 73, 979 stubble-consuming occurrences have been recorded to date.
