Patna: Air quality in Bihar showed a mixed trend on Wednesday, with a slight overall improvement but pollution remaining a concern in many urban areas. According to official data, moderate levels of air pollution were recorded in 11 cities, including the state capital, Patna. Danapur, a major part of the Patna urban region, reported one of the highest pollution levels with an Air Quality Index (AQI) of 177. In other parts of Patna, Gandhi Maidan recorded an AQI of 140, Samanpura 119, and Shikarpur in Patna City 105, all falling under the moderately polluted category.
Hajipur recorded the worst air quality in the state, with an AQI of 180, making it the most polluted city in Bihar for the day. Other cities such as Saharsa (150), Siwan (126), Munger (120), Bettiah (116), Motihari (108), Katihar (107), Samastipur (105), Muzaffarpur (104), and Aurangabad (102) also reported moderate pollution levels. Though these figures do not indicate severe pollution, health experts warn that continuous exposure to such air can cause breathing problems, eye irritation, and discomfort, especially for children, elderly people, and those already suffering from respiratory illnesses.
At the same time, air quality remained satisfactory in eight cities across the state, offering some relief to residents. Biharsharif recorded an AQI of 98, Bhagalpur 93, Gaya 89, Rajgir 87, Chhapra 86, Ara 66, Sasaram 65, and Kishanganj 57. These cities stayed within safe limits, suggesting comparatively cleaner air and better living conditions for the day. Officials said that lower traffic pressure and fewer construction activities helped keep pollution levels under control in these areas.
The Bihar State Pollution Control Board explained that weather conditions play a major role in the rise of pollution during winter. Increased humidity causes dust and fine particles to remain suspended in the lower atmosphere, while falling temperatures make the air heavier, trapping pollutants near the ground. Rising vehicle numbers and ongoing construction work have also added to PM2.5 pollution in many cities. Officials said air quality may continue to change in the coming days and advised people to limit outdoor activities during peak pollution hours and take basic precautions to protect their health.
