LUCKNOW: Even as reports of haze and low visibility in northern region hogged headlines, the situation in the state capital has not been any better either. Lucknow has also been witnessing smog for the last two days with pollution levels being many times of permissible standards.

The rapid fall in air quality and visibility began on Monday evening as moisture combined with pollutants shrouded the city .

The Air Quality Index (AQI) in the city was in the higher ranges of very poor and severe air quality categories.

Experts in UP Pollution Control Board said that more than local reasons, the burning of agriculture waste in Punjab and Haryana is contributing to haze formation and high air pollution levels.

"Burning of agriculture waste is rampant in Punjab and Haryana between October-end and November start. Winds are carrying the pollutants to Delhi and UP," said sources.

According to the live air quality monitoring station of the Central Pollution Control Board, the PM2.5 levels in Lalbagh area almost doubled on Tuesday .

"Our environment monitoring division noted that PM2.5 levels in Lalbagh increased from 150 micrograms to almost 300 micrograms in a day , many times over permissible limit of 60," said IITR director Alok Dhawan.

As per CPCB data, the air pollution levels at Lalbagh with PM2.5 concentration was 261.06 micrograms per cubic metre of air on Monday which increased to 326.24 micrograms.

Not Only Lalbagh, at Talkatora the levels increased from 369 to 333 and at Central school, Aliganj pollutants increased from 142.64 to 222.84 micrograms. The toxic substances kept on ri sing throughout the day Tuesday The average values for Tuesday at 4pm showed the air quality to be `severe' in Noida, Ghaziabad and Moradabad while it was `very poor' for Agra, Lucknow and Kanpur.

Since wind velocity has reduced by 3 to 4 km per hour in recent days, pollutants have accumulated and stagnated. The situation will linger on for few days, said experts.
