Air Quality

Air Quality Index:

The Air Quality Index (AQI) is an index for reporting how clean or polluted your air is and is generated using local air quality monitoring data. The AQI focuses on health effects you may experience after a long duration of breathing polluted air. Check the AQI being measured at a pollution monitor near you online.
