Wildfire smoke and lung health

Every year, fire season in BC seems to be getting longer and more extreme, causing some of the worst air quality in British Columbia, and causing health problems for those with and without chronic lung disease.

Wildfire smoke is a complex mixture of different air pollutants, including fine particulate matter (PM2.5), carbon monoxide, nitrogen oxides, volatile organic compounds, and trace amounts of heavy metals. The mixture can change depending on the fuels (types of trees, brush, grasses, or building materials) and the atmospheric conditions. Although wildfire smoke is generated outdoors, it can travel indoors through windows, doors, vents, and other openings.

When conditions are smoky, more people who are exposed to the novel coronavirus may develop COVID-19 and some cases of COVID-19 may become more severe. Follow the link below to learn more.
