Long-term exposure to wildland fire smoke PM_2.5 and mortality in the contiguous United States.

ABSTRACT: Despite the substantial evidence on the health effects of short-term exposure to ambient fine particles (PM_2.5), including increasing studies focusing on those from wildland fire smoke, the impacts of long-term wildland fire smoke PM_2.5 exposure remain unclear. We investigated the association between long-term exposure to wildland fire smoke PM_2.5 and nonaccidental mortality and mortality from a wide range of specific causes in all 3,108 counties in the contiguous United States, 2007 to 2020. Controlling for nonsmoke PM_2.5, air temperature, and unmeasured spatial and temporal confounders, we found a nonlinear association between 12-mo moving average concentration of smoke PM_2.5 and monthly nonaccidental mortality rate.
