Di­wali ef­fect stays as slow winds keep air qual­ity poor

The Times of India (Mumbai edition) - - TIMES CITY -

Mum­bai: Satur­day’s slug­gish winds did not do much good to the city as the qual­ity of air im­proved only marginally. While the Sys­tem of Air Qual­ity Weather Fore­cast­ing and Re­search (SA­FAR) had fore­cast the air qual­ity in­dex to im­prove to 221, it only went to 231 up to Satur­day evening from Fri­day’s 242.

On the day af­ter Di­wali (Thurs­day Novem­ber 8), Mum­bai recorded an AQI of 305. An AQI be­tween 301and 400 is con­sid­ered very poor and peo­ple with heart or lung dis­eases, older adults and chil­dren should avoid ex­er­tion. On Fri­day, the air qual­ity im­proved to 242, bring­ing it into the poor cat­e­gory, where peo­ple with heart or lung dis­ease, older adults and chil­dren should re­duce pro­longed or heavy ex­er­tion. On Satur­day, it con­tin­ued to stay in the poor cat­e­gory.

“The slow dis­per­sal of pol­lu­tants is due to slow wind speeds. This is nor­mal for Mum­bai dur­ing the win­ters,” said Gufran Beig, project di­rec­tor, SA­FAR.

Among the 10 lo­ca­tions mon­i­tored by SA­FAR, the most pol­luted con­tin­ued to re­main And­heri with an AQI of 379. It had recorded an AQI of 452 on the day af­ter Di­wali. The other lo­ca­tions which were in the very poor cat­e­gory (301 to 400) on Satur­day were Maz­gaon and Malad. The least pol­luted lo­ca­tion was Chem­bur with an AQI of 82.

SA­FAR has fore­cast the over­all AQI to im­prove only marginally to 229 on Sun­day. The air qual­ity is ex­pected to go into the mod­er­ate cat­e­gory (101 to 200) only af­ter a cou­ple of days.
