This Human Health Risk Assessment for Ambient Nitrogen Dioxide (NO2) is a comprehensive review of the most relevant health- and exposure-related science for this air pollutant, prepared by the Air Quality Assessment Section of Health Canada.
Health Canada undertook a health risk assessment of sulphur dioxide (SO2) in order to update the available information on adverse effects of SO2 to human health, determine recent Canadian SO2 exposure levels, and to inform the revision or development of Canadian ambient air quality objectives/standards.
This guidance document Federal Contaminated Site Risk Assessment in Canada: Supplemental Guidance on Human Health Risk Assessment of Air Quality, Version 2.0 was prepared to provide guidance for custodial departments.
The present document reviews the epidemiological, toxicological, and exposure research on NO2 that has been published since 1987, and proposes new short- and long-term indoor air exposure limits.
Air contaminants are pollutants that are present in the air and can put your health at risk. Learn about the different indoor air contaminants.
In the oil sands air monitoring component, nitrogen dioxide (NO2) and sulphur dioxide (SO2) levels are monitored by ground-based instruments, satellites and other measurements. Monitoring of air pollutants from satellites is becoming an alternative to surface and aircraft measurements, and allows for better understanding of the global distribution, sources and trends of pollutants. Using satellite data for the oil sands region, high-resolution air pollutant maps show distinct concentrations of NO2 (Figure 1a) and SO2 (Figure 1b) over an area (roughly 30 km x 50 km, or 19 miles x 31 miles) of intensive oil sands surface mining. The map shows that NO2 concentrations are significant and are comparable to measurements made over large, individual sources such as coal-burning power plants.
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, nitrogen dioxide, and volatile organic compounds at the national, regional and urban levels and at local monitoring stations. The national and regional indicators are presented with their corresponding Canadian Ambient Air Quality Standard when available. Canadians are exposed to air pollutants on a daily basis, and this exposure can cause adverse health and environmental effects.
Hourly ambient nitrogen oxides (NOx, NO2, NO) data in parts per billion from provincial ambient air quality monitoring stations across Nova Scotia up to the end of 2021. This air quality station was established to replace the "Halifax Vogue" air quality monitoring station which ceased monitoring at the end of 2017. The Halifax Vogue station was less than 1 block away from the new "Halifax Johnston" station.
