monsoon season and a trifle higher than the 32 recorded on October 12, 2017. Good rainfall over a long stretch in July and rains continuing in August had washed away the particulate matter (PM 10 and 2.5) and made it settle down while strong wind helped in further dispersion.
Construction activity being nil to negligible in the rains, besides the rains have helped the dust particles (PM10 and 2.5) to settle down and also, the carbon particles from vehicle emission dissolve; the strong winds helped further in dispersion, said the NMMC environment department.
AQI though was highest for Malad (75),
Andheri (61) and
Borivali (52). The air quality was in the satisfactory category; health risk said, "no risk," unlike the good category "no risk at all," but the advisory remained-"enjoy the day."
