The city has recorded relatively reduced air pollution compared to the past two weeks. The Air Quality Index (AQI) which is used to measure air pollution through the presence of various pollutants like particulate matter, nitrogen oxide, carbon monoxide and ozone has shown a relative improvement at various parts of the city.
According to the AQI measured by System of Air Quality and Weather Forecasting and Research (SAFAR) at nine spots in Mumbai and one in Navi Mumbai, the AQI has been the highest in Andheri at 303 which had reached 382 in the first week of January.
Apart from Andheri and Malad where the AQI fell in the ‘very poor’ category, at other parts of the city, including Bhandup, Chembur, BKC, Borivali, Mazgaon and Navi Mumbai, the AQI fell into ‘poor’ category. Only at Worli and Colaba, it fell in the ‘good’ category, 93 and 88, respectively.
“The pollution level this week has been less compared to the first two weeks of January. In the previous two weeks, the winds were calmer which led to the dust and pollutants getting accumulated,” Gufran Beig, project director, SAFAR said.
He added that in the next few days the wind speed was expected to increase which might reduce pollution in the city.
In terms of the weather, Santacruz recorded a minimum of 16.0 degree centigrade on Monday and a maximum of 21.3. Colaba recorded a minimum of 19.5 degree centigrade and a maximum of 28.4.
IMD officials said that the temperature would continue to remain within the same range for the next few days due to a change in the direction of the wind. “The wind direction over the city is northerly, currently. It was north-westerly earlier. This brought down the temperature and it will remain so for the next few days,” said VK Rajeev, director, IMD, western region.
