Health Impact Assessment of the 2020 Washington State Wildfire Smoke Episode: Excess Health Burden Attributable to Increased PM_2.5 Exposures and Potential Exposure Reductions.

ABSTRACT: Major wildfires starting in the summer of 2020 along the west coast of the United States made PM_2.5 concentrations in this region rank among the highest in the world. Washington was impacted both by active wildfires in the state and aged wood smoke transported from fires in Oregon and California. This study aims to estimate the magnitude and disproportionate spatial impacts of increased PM_2.5 concentrations attributable to these wildfires on population health. Daily PM_2.5 concentrations for each county before and during the 2020 Washington wildfire episode (September 7-19) were obtained from regulatory air monitors. Utilizing previously established concentration-response function (CRF) of PM_2.5 (CRF of total PM_2.5) and odds ratio (OR)
