New Delhi: Recent Analysis by Science and Environmental Centers (CSE) has found that the November Smog episode synchronizes throughout the northern region, but they linger for a longer period only in Delhi, other NCR regions and Uttar Pradesh during It’s winter.
“Initial winter smoke synchronization throughout the northern region but lasted longer in Delhi-NCR,” the study said, adding that the change in atmosphere during the winter, which includes inversion, calm conditions, wind direction changes and seasonal decline in North India, concerned pollution .
“This then stumbles into the ‘severe’ category with smoke from agricultural fires and diwali firecrackers.” Although, this research shows, air quality increases from the “severe” category to “poor” and “moderate” in Punjab and Haryana North after the fire of fire stumps, it remains “very poor” in NCR and until February.
“The city of Rajasthan also shows the impact of smoke, but at a lower level with a relatively less polluted air for the rest of the winter.” This analysis reveals that most smaller cities have an annual average annual average level but reports are comparable to or worse than Delhi during the usual episode of Smog in November.
For example, Delhi’s annual average rate is 97ug / m3 and Agra 20% lower at 78ug / m3.
But during the early winter this year, the average PM2.5 weekly level in Agra was 282ug / m3 and exceeded 5% of Delhi’s 270.
Tracking pollution levels in your city “This analysis has placed the spotlight in the cities of Punjab, Haryana, Uttar Pradesh, Rajasthan and NCR to understand the pattern of pollution synchronized during the winter …
It shows even small cities with a lower annual average rate noting the same level of pollution or even worse than Delhi.
This demands action On the scale and speed in all the main sectors of pollution in a larger area, “said Anumite Roychowdhury, Executive Director of Research and Advocacy in CSE.
While all North Indians are vulnerable to pollution buildup, the average annual NCR as a whole is one of the highest in the region.
This year, Ghaziabad has been the most polluted city in the region with an average of 110ug / m3 to 30 November.
Moradabad is the most polluted city outside the NCR with the PM2.5 level at 96ug / m3.
The city of NCR also saw a doubling increase in nitrogen dioxide.
Long-term trends show that the average fire radiation – the level of radiation energy emitted by fire – in Punjab has increased since 2017 and the average this season is the highest since monitoring begins in 2012.
“This, coupled with overall fire increase Calculate in Punjab, may also contribute to the increase in smoke severity this year, “said research.
