New Delhi: As pollution levels rise this year, the downturn caused by the severe pandemic blockade in 2020 will not persist, a new analysis of regional pollution trends by the Center for Science and Environment (CSE) shows. increase.
“This analysis of real-time air quality data from 2019 to 2021 rebounds from the pollution decline caused by the 2020 pandemic’s hard lockdown phase, with 2021 levels already rising. However, in many cases the levels are still lower than in 2019. This is all to prevent further deterioration in the region and thwart trends in the region. It emphasizes the urgency of expanding action in the sector. “
As a result, studies have shown that the eastern states of India, namely Bihar, West Bengal, and Orissa, are now experiencing the pain of increased air pollution in winter.
As winter smog swallows North India in early November begins to spread eastward from late December to early January, Bihar, West Bengal and Orissa are regions that already have winter reversals and cool, mild conditions. Highly affected during this time of confinement of pollution.
“In these states, real-time air quality monitoring is beginning to expand to provide up-to-date, real-time information about air quality, but serious concerns about data gaps and gaps make proper risk assessment difficult. At some stations in Bihar and Orissa, data availability is so low that trends cannot be assessed. Data quality control is required, “said Program Manager, Urban Data Analytics Lab, CSE. Said Avikal Somvanshi.
This new analysis of real-time pollution data by CSE is part of the Urban Data Analytics Lab’s Air Quality Tracker Initiative, whose purpose is to understand pollution trends and scales in different regions with real-time air quality monitoring. That is. system. This is an assessment of annual and seasonal trends in PM2.5 concentrations from January 1, 2019 to January 4, 2022, with 29 consecutive majors spanning 12 cities in the above three states. It is intended for the temperament monitoring station (CAAQMS). ..
