Patna's air quality better after rain
PATNA: After remaining ‘very poor' for the last five days, the air quality in the state capital slightly improved to come in the “poor” category on Sunday.
As per the Central Pollution Control Board (CPCB) bulletin, the overall air quality index (AQI) of the city was recorded at 291 on Sunday, compared to 375 on Saturday. The improvement was attributed to a brief spell of rain in the morning.
The Air Quality Early Warning System of the ministry of earth sciences forecastes cleaner air in Patna in the next two days owing to favourable meteorological conditions and relatively stronger winds, which may help in dispersion of the pollutants trapped in the environment.

An AQI between’0’ and 50 is considered ‘good’, 51-100 ‘satisfactory’, 101-200 ‘moderate’, 201-300 ‘poor’, 301-400 ‘very poor’ and 401-500 ‘severe’. A ‘poor’ AQI essentially means that people may suffer respiratory illness or breathing discomfort on prolonged exposure. The pollutant level of the city is calculated on the AQI level of six continuous ambient air quality monitoring stations in Patna. Three of them were in poor zone — BIT-Mesra, Patna (230), SK Memorial Hall (246) and DRM office-Khagaul (268). The other three other stations registered ‘very poor’ AQI -- Eco Park (343), Planetarium (334) and Patna City (325).
