Ozone levels are usually worst from mid\u002Dafternoon to early evening on warm summer days
The poor air is expected to continue all week due to hot, sunny weather, and the air will remain hazy as a result of a plume of wildfire smoke from the Nohomin Creek blaze outside Lytton. However, that smoke hasn’t yet had a significant impact on the amount of fine particulate matter at ground level.
Metro Vancouver explains in the advisory that ground-level ozone “is not emitted directly into the air. It is formed when nitrogen oxides and volatile organic compounds react in the air in the presence of sunlight.”Residents are advised to avoid strenuous outdoor activity especially during that part of the day. Choose walking over running to avoid breathing hard.Article content
Those with underlying conditions, such as heart or lung disease, emphysema, asthma or COPD are most at risk from high ozone levels. Pregnant women, children, the elderly, the homeless and those who work strenuously outside such as in construction or agriculture are also vulnerable. As always in summer, it is important to stay cool and hydrated. Seek out indoor spaces with air conditioning for relief from both heat and air pollution. Consider a portable air conditioner if you don’t have central air.
Anyone experiencing chest discomfort, shortness of breath, coughing or wheezing should seek medical attention, or call 911 if it’s an emergency.
