Smoke from wildfires contains small pollutants known as particulate matter, or PM2.5, which can reach the lungs and bloodstream once inhaled.

Parts of the United States will be at risk of smoke for the foreseeable future depending on weather patterns and fire outbreaks because Canada is experiencing its worst fire season on record. More than nine million acres have burned so far this year, an area that is roughly the size of Indiana.
British Columbia has had more than 1,000 fires since April. Those fires have already burned nearly three times the amount of land compared to an average year in British Columbia over the past 10 years, the province’s wildfire service said.
