In Bengaluru, the typical focus of PM2.5 this November was 33.49µg/m3 as in comparison with 40.33µg/m3 in November 2019 — a drop of 16.96 per cent. Bapuji Nagar and Jaynagar remained hotspots with a median PM2.5 focus of 42µg/m3 and 39µg/m3, respectively.
In line with the evaluation, Bengaluru had solely 12 days in November 2020 when the PM2.5 focus remained beneath the prescribed WHO requirements. BTM format within the metropolis was the least-polluted space with a median PM2.5 focus of round 20µg/m3.
