Mumbai weather updates: City's AQI remains 'good'

On Thursday, October 17, the Central Pollution Control Board's SAMEER app reported in its latest Mumbai weather updates that the city's air quality was in the 'good' category, with an Air Quality Index (AQI) of 82 at 9:05 AM. However, a private AQI monitoring agency suggested that the current concentration of pollutant PM2.5 in the city was 2.1 times above the recommended limit set by the World Health Organisation's 24-hour air quality guidelines value.

Unlike its streak so far, many areas across Mumbai - per the SAMEER app dashboard - showed 'good' AQI. However, Bandra Kurla Complex, Mazgaon, Kherwadi and Khindipada's AQI had slipped further into the 'moderate' category at 132, 154, 113 and 130 respectively.

According to data from the SAMEER app, Navi Mumbai recorded air quality in the 'good' category with an AQI of 77, while Thane registered a 'good' AQI of 57.

The air quality index from 0 to 100 is considered 'good', 100 to 200 'moderate', 200 to 300 'poor', 300 to 400 'very poor' and from 400 to 500 or above 'severe'.

Meanwhile, as air pollution levels continue to rise in Mumbai, the Brihanmumbai Municipal Corporation (BMC) has revised guidelines issued last year for construction sites. The civic body will also form squads at the ward level to visit construction sites and act if guidelines are flouted. Sensor-based air pollution monitoring systems will be installed at all construction project work sites and immediate action to be taken if pollution levels are detected above the limit.
