For immediate release
July 26, 2003
Effective immediately, the Ontario Ministry of the Environment has lifted its Smog Advisory for the following regions:
| Brant-Haldimand-Norfolk | Prince Edward County |
| Elgin | Quinte-Northumberland |
| Halton-Peel | Sarnia-Lambton |
| Hamilton | Toronto |
| Huron-Perth | Waterloo-Wellington-Dufferin |
| London-Middlesex-Oxford | Windsor-Essex-Chatham-Kent |
| Niagara | York-Durham |
| Peterborough/Kawarthas |
Clouds and unsettled weather is moving across Ontario. These weather conditions have resulted in cleaner air.
Smog is a hazy mix of pollutants made up of ground-level ozone, fine particulate matter and other pollutants. During the summer months, more-than half of Ontario’s smog-causing pollution originates in the United States. In cooler months, domestic sources can be significant contributors to the formation of fine particulate matter.
Ontario has one of Canada’s best air quality monitoring systems. The ministry issues Smog Advisory and Smog Watch notices in order to provide the people of Ontario with the information they need to protect themselves from the potential health effects of smog.
The Web site www.airqualityontario.com
contains a list of “spare the air” actions (www.airqualityontario.com/science/spareair.cfm)
to help combat smog and minimize its effect on sensitive populations. If you
want to learn more about air quality, visit the Ministry of the Environment’s
Web site at www.ene.gov.on.ca.
