There may be blue skies throughout Metro Vancouver and the Fraser Valley; however, Environment Canada cautions that the air quality is still poor.

In fact, the Air Advisory was finally removed over the weekend, as the cool sea air blew smog out of the Lower Mainland.

Despite the cool and damp weather, smoke from wildfires both within and outside the area has moved into all parts of Metro Vancouver and the Fraser Valley. As a result, the advisory will continue until there is a change in weather or fire conditions.

As such, Metro Vancouver will continue to monitor the levels of fine particulate matter.

With that being said, persons with chronic underlying medical conditions should postpone strenuous exercise until the advisory is lifted. In addition, exposure is particularly a concern for infants and the elderly; it is also a concern for those who have diabetes, and lung or heart disease.

If you are experiencing symptoms such as chest discomfort, shortness of breath, coughing or wheezing, follow the advice of your healthcare provider.

Air Quality Advisory

Last week, parts of Metro Vancouver had air quality equivalent to smoking 8 cigarettes a day. Whats more, Metro Vancouver’s air quality was the worst in the North America this summer.

While the wildfires are creating the smoke, lung irritation doesn’t come directly from the smoke, but rather the smog. Smog is formed when nitrogen oxides (pollutants emitted when fuels are burned) and volatile organic compounds (emitted from solvents) react in the air in the presence of sunlight.

While BC may have sultry skies well into September, a change in weather may improve the local environment.
