High air pollution triggered by weather conditions hit most of north India on Tuesday morning, including Punjab and Haryana, indicating worse days ahead for people with breathing problems.
In Haryana, Faridabad recorded particulate matter three times higher than the national air quality standard (100 micro grams per cubic metre). Similar high levels of air pollution were recorded in other parts of the state, including Ambala and Panipat.
In Punjab, burning of paddy stubble contributed to high air pollution levels. Amritsar was among the worst-affected cities, followed by Jalandhar.
Particulate matter levels rose three to four times of the national standard on Tuesday morning, further increasing during the day due to vehicular traffic after a two-day Diwali break.
Agra in Uttar Pradesh saw particulate matter level reaching about 350 micro grams per cubic metre, whereas it was more than 250 in Lucknow. The Central Pollution Control Board's (CPCB) daily air pollution monitor showed high pollution levels in most parts of western Uttar Pradesh.
Based on inputs from the weather department, the CPCB believes that the pollution levels in north India will remain on the higher side for the new few days as there is poor disbursal mechanism for pollutants.
