Description: This report, 28th in a series, summarizes the state of ambient air quality in Ontario in 1998. It covers measured levels of ozone (O3), particles and other criteria contaminants such as sulphur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO) and total reduced sulphur (TRS) compounds. In addition, the report summarizes the 1998 Air Quality Index statistics from the real-time air quality index information system, examines regional smog episodes and provides an international perspective on air quality. Once again, the focus of this year’s publication is to report on the state of ambient air quality.
