What is the average AQHI for the City of Winnipeg?
Recent monitoring has shown that the health risks associated with air quality for the City of Winnipeg are generally low, with an average AQHI rating of around three or lower. How is a community’s AQHI calculated? The Air Quality Health Index (AQHI) is based on the relative risk posed by a combination of common air pollutants that are known to harm human health. These pollutants include Ground-level Ozone (O3), Particulate Matter (PM2.5), and Nitrogen Dioxide (NO2). For more information on these pollutants, please visit:http://www.ec.gc.ca/cas-aqhi/default.asp?lang=En&n=0929D3A1-1. The AQHI does not measure the health effects of odour, pollen, dust, heat or humidity. Other air pollutants such as sulphur dioxide and carbon monoxide, are not included in the index because their health effects are largely predicted by measures of ground-level ozone, nitrogen dioxide and particulate matter. Can weather conditions affect the AQHI? Weather conditions can affect air quality and elevate the rea
