National Air Pollution Surveillance (NAPS) Network, air quality in Canada : 2001 summary and 1990-2001 trend analysis / issued by Environmental Technology Advancement Directorate.: En84-1/2004E-PDF
This report characterizes air quality in 2001 across Canada using measurements from the National Air Pollution Surveillance (NAPS) network. The report is intended to be a supplement to the NAPS Annual Data Summary for 2001 (EC 2002) and illustrates geographical and temporal variations in pollutant concentrations across Canada. Trends in pollutant levels over the period 1990 to 2001 are also provided. The atmospheric pollutants included in this report are sulphur dioxide, carbon monoxide, ground-level ozone, nitrogen oxides, particulate matter, and a number of organic and inorganic compounds. The air quality in Canada varies by both geographical location and time of year, and certain pollutants are associated with and present at levels of concern in specific areas.
