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.
