How was the Air Quality Health Index developed?
The Air Quality Health Index was developed by Health Canada and Environment Canada in collaboration with provincial governments and nongovernmental organizations in the health and environment sectors. The Air Quality Health Index is the product of a number of years of research and is based on the latest scientific data in the field. The scientists who created it estimated the daily variation in the mortality risk in ten cities from 1998 to 2000 and rated the data on a ten-point scale.
