Canadians spend approximately 90% of their time indoors. While the first step to ensure good indoor air quality (IAQ) is to reduce indoor sources of pollution, ventilation is also an essential strategy. Proper ventilation reduces pollutant and moisture levels that may directly or indirectly...

Outdoor air pollution comes from a variety of sources, and even at low levels, has an impact on human health. It leads to disease, increased hospitalizations and even premature death.

Health effects from air pollution can depend on the source.

Follow these tips to reduce your risk of health effects from air pollution.

Traffic is a major source of air pollution especially in urban areas. Traffic-related air pollution (TRAP) is a mixture of gases and particles that include many different chemicals from cars, buses and trucks. TRAP includes emissions from exhaust, evaporation of fuel, and tire and brake wear.

Health Canada completed the Human Health Risk Assessment for Diesel Exhaust, a comprehensive review and analysis of the potential adverse health effects associated with diesel fuel use in Canada. The report focuses on diesel exhaust (DE) emissions from on-road and off-road vehicles (excluding...

Health Canada completed the Human Health Risk Assessment for Gasoline Exhaust, a comprehensive review and analysis of the potential adverse health effects associated with gasoline fuel use in Canada. The report focuses on gasoline exhaust (GE) and vehicle emissions from on-road and off-road...

The general approach employed is as comprehensive as the available information allows and is comparative in nature, i.e., the impacts of biodiesel blends are compared to those of conventional ultra low sulphur diesel (ULSD) and presented as relative risks and benefits. The primary consideration...

This review is intended to support the development of Canadian Ambient Air Quality Standards (CAAQS) for NO2; these standards are one of the elements of the federal-provincial-territorial Air Quality Management System.

The Air Quality Assessment Section of 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...
