The Air Quality Health Index (AQHI) is a scale designed to help quantify the quality of the air in a certain region on a scale from 1 to 10. When the amount of air pollution is very high, the number is reported as 10+. It also includes a category that describes the health risk associated with the...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Air quality indicators track ambient concentrations of fine particulate matter, ground-level ozone, sulphur dioxide,...

At all locations the TGM measurements were made using automatic Tekran ® 2537 mercury vapour analyzers (described in detail in Poissant, 1997). The air is typically sampled at flow rates between 1.0 and 1.5 L/min (depending on location) and is passed through a Teflon filter (47 mm diameter; 0.45...
