About Air Quality in Howrah

The Air Quality Index (AQI) in Howrah is measured using monitoring stations that track six key pollutants: PM2.5, PM10, ground-level ozone, nitrogen dioxide, sulfur dioxide, and carbon monoxide. The AQI is calculated using US EPA standards and ranges from 0 (excellent) to 500 (hazardous).

PM2.5 is typically the dominant pollutant in Howrah during high-pollution periods. Fine particulate matter from traffic, industry, and seasonal factors can push AQI above 150, which is considered unhealthy for all groups.
