With the Diwali festivities coming to an end, air quality in the city further improved Sunday with the Air Quality Index (AQI) reflecting ‘satisfactory’ levels. According to the data compiled by the System of Air Quality Forecasting and Research (SAFAR), the PM10 and PM2.5 levels came down to 87 µgm-3 and 51 µgm-3, respectively. The air quality in the city Sunday was much better than in Delhi, and even Pune and Ahmedabad that witnessed moderate air pollution levels.
While most parts of the city had good quality air, Borivali, Mazagaon and Navi Mumbai reflected moderate levels of pollution with PM2.5 levels at 126 µgm-3, 104 µgm-3 and 113 µgm-3, respectively. PM2.5 are minute dust particles that can easily enter the bloodstream through the lungs. According to SAFAR’s forecast, the air quality in the city is likely to remain at the same levels on Monday and Tuesday.
“The pollution levels have come down to the permissible limits now. Strong winds originating from the sea have dispersed all the pollution. Usually, the pollution remains in the air for at least a week, but this time because of the presence of the monsoon winds they were dispersed sooner,” said Dr Gufran Beig, project director, SAFAR. He added: “This year, the pollution levels were slightly lower than that in the previous years, except the day after Diwali…”
