Cardiopulmonary hospitalization risks from wildfire and non-wildfire PM_2.5 in 20 US states.

ABSTRACT:

Importance

Given the increasing wildfire activity in the US, assessment of the health impacts of wildfire-specific fine particulate matter (PM_2.5), a growing source of surface air pollution, and its relative toxicity compared to non-wildfire PM_2.5 is needed to support mitigation strategies.

Objective

To investigate associations of long-term exposure of wildfire-specific and non-wildfire PM_2.5 with cardiopulmonary hospitalization risks.

Design setting and participants

We obtained over 89 million cardiopulmonary hospitalizations for residents across 20 US states from 2006 to 2019 from the State Inpatient Databases. We assigned estimated 2-year average concentrations of wildfire-specific and non-wildfire PM_2.5 to each hospitali
