It is not fog; it is haze that could be seen throughout the day on Saturday with air quality index (AQI) read 219 (poor) and is expected at around same range today..
Researchers said weather conditions were responsible for the poor air quality. “While temperatures are not very low in Mumbai, the high moisture levels are allowing pollutant particles to tread close to the surface. Owing to negligent wind speed and the process of inversion, the particles are not dispersing fast enough, leading to haze formation,” said Gufran Beig, project director, SAFAR. “Until wind speed picks up, the haze is likely to stay.”
Of the 10 locations in Mumbai, Bandra Kurla Complex (BKC) had the most polluted air with an AQI of 313 (very poor), followed by Navi Mumbai at 303 (very poor). The cleanest air in the city was recorded at Worli with an AQI of 124 (moderate).
