Guwahati's Air Quality has dropped over the last month for various reasons. Today, Guwahati seems covered in white as the dust storm looms over the city. Guwahati's air quality has stayed in the 'Very Poor' category for a month as per the daily Air Quality Index (AQI) bulletin published by the Central Pollution Control Board. Air pollution has increased to an alarming level, forcing many city-bound flights to divert due to low visibility from a thick dust cloud.
