Air pollution occurs when the air contains harmful amounts of gases, dust, fumes, or odours.
Examples of these pollutants are car exhaust, smoke, and ground level ozone. The Air Quality Health Index provides hourly air quality readings and related health messages.
Air quality has a direct impact on the health of humans and the environment. British Columbians can use the Air Quality Health Index to check the quality of outdoor air before heading off to work or play.
