Wildfire Related Air Pollution Exposure and Cognitive Function Pilot Study

• Exposures will take place in a booth-like exposure chamber (1 x 0.7 x 1.8 m) with glass upper panels. One person will be exposed at a time.
• Simulated wildfire smoke will be generated by burning pine wood at a temperature that mimics smoldering combustion. The levels of smoke introduced into the exposure chamber are similar to those found during outdoor bonfires and wildfire events. The levels of particulate matter (PM) will be closely monitored during the exposure.

Inclusion criteria

• Healthy

• Consumption of alcohol in the previous 24 hours.
