Metro Vancouver is continuing the fine particulate matter advisory that has been in effect since September 8 as wildfire smoke from fires in the US continues to persist in the region.
Air quality has continued to improve since yesterday, but ground-level smoke still remains and is expected to remain through the week.
However, a forecast of rain for Friday is expected to bring further improvements on the weekend.
Fine particulate matter, also known as PM2.5, refers to airborne solid or liquid droplets with a diameter of 2.5 micrometres (µm) or less. PM2.5 can easily penetrate indoors because of its small size.
Persons with chronic underlying medical conditions or acute infections such as COVID-19 should postpone or reduce outdoor physical activity until the advisory is lifted, especially if breathing feels uncomfortable.
Exposure to PM2.5 is particularly a concern for people with underlying conditions such as lung disease, heart disease, chronic obstructive pulmonary disease (COPD), asthma, and/or diabetes, individuals with respiratory infections such as COVID-19, pregnant women and infants, children, and older adults.
Individuals who are socially marginalized may also be at elevated risk.
If you are experiencing symptoms such as chest discomfort, shortness of breath, coughing or wheezing, seek prompt medical attention. Call 9-1-1 in the case of an emergency.
