The air quality in Bengaluru which was “moderate” and “satisfactory” on the second day of the Deepavali festivities on October 21, saw an improvement on Wednesday as many pollution monitoring stations “satisfactory” air quality.
As per the Central Pollution Control Board, Air Quality Index (AQI) data recorded on Wednesday at 7 p.m., nine of the 14 stations in Bengaluru showed the air quality as “ satisfactory.”
Three stations Hebbal (29 AQI), Homegowdanagar (45 AQI) and Silk Board (48 AQI) showed the air quality as “good.”
Only two stations BTM Layout (115 AQI) and BWSSB Kadubeesanahalli (121 AQI) recorded air quality at a moderate level.
In contrast, six monitoring stations showed the air quality at a moderate level on October 21.
AQI ranging from 0-50 is considered good with minimal health impact. The AQI ranging from 51 t to 100 is considered satisfactory and the possible health impacts are minor breathing discomfort to sensitive people.
AQI ranging between 101 and 200 is considered moderate and the possible health impacts are breathing discomfort to the people with lungs, asthma and heart diseases.
AQI ranging from 301-400 is considered very poor, and the health impacts are respiratory illness on prolonged exposure. AQI ranging from 401-500 is considered severe, and the health impacts affect healthy people and seriously impact those with existing diseases.
On Wednesday (October 22), Particulate Matter (PM) 10 was the prominent pollutant in stations in 11 station stations followed by Particulate Matter (PM) 2.5 in three stations.
PM10 (particulate matter of diameter 10 micrometers or less) and PM2.5 (particulate matter of diameter 2.5 micrometres or less).
A light spell of rain on Wednesday (October 22) evening also could have contributed to an improvement in air quality as fewer people were seen bursting fire crackers compared to the previous two days.
The Karnataka State Pollution Control Board has allowed the bursting of only green crackers between 8 p.m. and 10 p.m. during the festivities.
