Smaller cities of Bihar more polluted than the big cities in Delhi-NCR

The average concentration of particulate matter 2.5 (PM2.5) in the cities of eastern India was the same as that in the cities of Delhi-NCR in the winter of 2021-22, according to a new report. 

Parsed regionally, eastern India was over three times as polluted as southern India and 22 per cent more polluted than northern India from October 15, 2021 to February 28, 2022, the analysis showed. 

The report was published by the Centre for Science and Environment (CSE), a Delhi-based non-profit. The analysis was based on real-time data from 326 official stations across 161 cities in 26 states and Union territories, displayed on the official website of the Central Pollution Control Board.

North India is notorious for its winter air pollution, caused mostly by stubble burning between crop cycles. 

New hotspots

During the study period, air quality in Bihar was particularly unhealthy, with six of its cities featuring in the top 10 most-polluted cities this winter, the analysis showed. Siwan in Bihar topped the list this winter, with a seasonal average of 187 microgram per cubic metre (ug/m3). 

The smaller cities of Bihar were found to be more polluted than the big cities in Delhi-NCR during the months for which data was studied. 

The results of the study demonstrated how the winter pollution challenge is not limited to mega cities or to one specific region, said Anumita Roychowdhury, executive director, research and advocacy, CSE. 

Quicker reforms and action in key sectors of pollution such as vehicles, industry, power plants and waste management are required “to bend the annual air pollution curve and daily spikes”, she added. 

Hisar in northern Haryana was the only city in the top 25 outside the sub-regions of Bihar and NCR, according to the report.
