Metro Vancouver has issued an air quality advisory due to high concentrations of ground-level ozone in the region.
The Metro Vancouver Regional District issued an advisory on Thursday, July 6, noting that hot temperatures and sunshine combined with wildfire smoke contributed to elevated ground-level ozone concentrations.
The advisory applies to northeast and southeast Metro Vancouver, as well as the central Fraser Valley and eastern Fraser Valley.
Currently, the air quality map shows that most of the Lower Mainland has a level two or low risk to health, meaning that there are no issues with the current air quality.
Metro Vancouver says the"fine particulate matter (PM2.5) concentrations have improved across the region and are now well below the 24-hour PM2.5 air quality threshold."
A decision to drop the advisory has not been made and it will remain in effect until further notice.
Environment Canada's air map also shows that the low risk may transition to a level five or moderate risk later in the day on Friday, July 7 across the Metro Vancouver region.
Saturday's forecast also includes a level four or moderate health risk.
At-risk populations should "consider reducing or rescheduling strenuous activities" outside if they experience symptoms. The general population won't need to change their behaviour unless they experience throat irritation or coughing.
If you are experiencing symptoms such as chest discomfort, shortness of breath, coughing, or wheezing, seek prompt medical attention. Call 911 in the case of an emergency.
