Mumbai (Maharashtra): Cyclone Nisarga and its accompanying rains seem to have had a positive impact on Mumbai's overall air quality index, which improved to 17 on Thursday, the best reading for this year as of now, an official said.
Mumbai continued to receive rainfall on Thursday, a day after the cyclone made landfall near Alibaug in neighbouring Raigad district.
The current air quality of Mumbai recorded at noon falls in the good category, that poses little or no health risk, according to the official website of the System of Air Quality and Weather Forecasting and Research (SAFAR).
The concentration of PM 2.5, tiny particulate matter less than 2.5 microns in diameter which can enter deep into the lungs and even the bloodstream, was recorded at 15 (good).
"This is the best record of the year till now. It is due to the combination of high-speed winds and accompanying rains that the air quality index (AQI) has improved," SAFAR director Dr Gufran Beig said.
