There will be a slight improvement in air quality today in North Shore but ground-level smoke will remain.
The smoke us also expected to continue until later this week, according to the latest air quality statement issued for Metro Vancouver.
The fine particulate matter advisory issued on September 8 also remains in place for Metro Vancouver and the Fraser Valley Regional District.
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. It can easily penetrate indoors because of its small size.
Persons with chronic underlying medical conditions or acute infections such as COVID-19 are asked to 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.
Indoor spaces with HEPA air cleaner filtration and air conditioning may offer relief from both heat and air pollution, but physical distancing guidelines for COVID-19 should still be observed, Metro Vancouver says..
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.
