The US is on track to experience its worst year for smoke exposure in decades, after wildfires in Canada sent toxic plumes drifting across the border to the Midwest and the East Coast earlier this summer.

In June and July, New York and Chicago saw more “very unhealthy” and “hazardous” air quality days for fine particle pollution (PM2.5) than in the same months every year since the Environmental Protection Agency began tracking PM2.5 nationally in 2000, a Bloomberg CityLab analysis of federal data found. In Washington, DC, the number of “very unhealthy” days reached the highest in over a decade.

On the EPA’s air quality index scale, these days correspond with the highest levels of public health concern. Extensive exposure to PM2.5 particles, the main pollutant found in smoke, can increase the risk of a variety of problems, including heart and respiratory disease, as well as premature death.
