On Monday, air quality of Patna remained poor with an AQI of 252 which was moderate till Sunday.

For regulating air pollution during winters, the Bihar State Pollution Control Board (BSPCB) has taken several initiatives which will yield desirable result in coming years.

Officials of the control board said that deterioration of air quality is linked with dip in mercury. Patna logged a maximum temperature of 27.2 degrees Celsius and a minimum temperature of 10 degrees Celsius on Tuesday.

BSPCB chairman Ashok Ghosh said, “When the temperature falls, dust particles rise along with winds, turning the air quality comparatively poorer. Air quality starts worsening from rainy season and peaks during winter every year. Besides, geographical factors are also responsible for worsening air quality as Patna is situated near the Gangetic plain where alluvial soil is in abundance. During winters, soil particles rise, contributing to air pollution.”

“We have introduced green technology at 60% brick kilns to reduce emission of hazardous gas. In the next two years, we expect to achieve 100% target. Besides, we are also working to concretise kuchcha pavements”, Ghosh added.

Meanwhile, environmentalist in the city appealed the residents not to burst crackers in the on-going wedding season to prevent further deterioration of air quality. Ramapati Kumar, chief executive officer of the Centre of Environment and Energy Development (CEED), said, “Poor air quality causes respiratory illnesses on prolonged exposure. With the wedding season on, people burst crackers, which leads to air and noise pollution. Vehicular movement and construction work have also gained momentum with the lift of lockdown. Environmental pollution cannot be reduced without active involvement of the public. Wearing face mask is the only way to avoid inhaling toxic pollutants.”
