Description: This report, the 32nd in a series, summarizes the state of ambient air quality in Ontario during 2002 and examines trends over time. It covers the measured levels of seven contaminants: ozone (O3), fine particulate matter (PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulphur dioxide (SO2), total reduced sulphur (TRS) compounds, and ambient mercury (Hg) in Ontario. An overview of the air quality of 10 cities in the Great Lakes Basin area is also provided in the report. The report also summarizes the results from the Air Quality Index (AQI) and Smog Alert programs and briefly examines smog episodes in 2002. Results for a selected number of volatile organic compounds (VOCs) are also reviewed.
