Patna was the second most polluted city in India on Sunday, recording an air quality index (AQI) of 316, which is classified as 'very poor'.
Other cities in the state that recorded 'poor' AQI are Siwan (282), Muzaffarpur (233), Hajipur (232) and Bettiah (221).
Greater Noida in UP was the most polluted city in the country with an AQI of 346, according to the Central Pollution Control Board (CPCB) bulletin at 4 pm.
'Very poor' air quality causes respiratory illness on prolonged exposure, according to the CPCB.
AQI is an assessment of air quality that takes into account pollutants, including PM 2.5 -- particulate matter less than 2.5 microns, and PM 10.
Bihar State Pollution Control Board (BSPCB) chairman Devendra Kumar Shukla told PTI, "It is true that the air quality has deteriorated in certain cities of the state. It is because of low wind speed, ongoing construction activities without following pollution control measures and recent fire incidents in Patna and surrounding areas." He said civic bodies will have to start sprinkling water to check the deteriorating AQI in the state capital.
"Rain will certainly bring some immediate relief. The BSPCB will soon intensify its drive to check deteriorating AQI levels in certain cities of the state," he added.

Delhi is gearing up to build one of India's most advanced e-waste processing facilities, and it's taking cues from Norway's cutting-edge model.
The national capital on Sunday recorded a maximum temperature of 33.6 degrees Celsius, 7.8 notches below the seasonal average, according to the India Meteorological Department (IMD).
Air Quality Management Commission admitted it has not conducted any research or study on pollution caused by diesel vehicles older than 10 years and petrol vehicles older than 15 years, which form the basis of the overage vehicle ban in Delhi-NCR.
Monsoon Diseases Prevention: Monsoon brings welcome relief but also triggers respiratory health issues like cold, flu, asthma and pneumonia, due to high humidity, mould, dust, air pollution and viral outbreaks.
The Supreme Court has upheld the powers of the pollution control boards to impose restitutionary and compensatory damages for environmental harm, saying that prevention and remediation must be at the heart of environmental governance.

Opinion | Why Indians Have Just Given Up On Air Pollution CrisisTanushree Ganguly
Friday December 20, 2024While some may argue that people in Delhi are now more aware of air pollution than they were a decade back, my rebuttal would be that awareness does not mean that people are concerned.

Friday November 08, 2024हमारी हवा जहरीली हो रही है. गुरुवार की शाम को जब मैं इस मुद्दे पर लिखने बैठी तो AQI लगातार 400 पार जाकर दम घोंट रहा था. बहुत लोगों को यह मामला बोरिंग लगे, लेकिन जब आप अपने साथ काम करने वालों को खांसते-हांफते देखते-सुनते हैं, तो चिंता होने लगती है. सुबह उठते ही दरवाजे खिड़कियां खोलने के लिए डॉक्टर मना कर रहे हैं. बड़े बुजुर्गों के लिए तो मॉर्निंग वॉक बाहर की दुनिया से सीधे संपर्क का ज़रिया है, लेकिन डॉक्टर इसकी भी मनाही कर रहे हैं.
