Associations of wildfire smoke PM_2.5 exposure with cardiorespiratory events in Colorado 2011-2014.

ABSTRACT:

Background

Substantial increases in wildfire activity have been recorded in recent decades. Wildfires influence the chemical composition and concentration of particulate matter ≤2.5 μm in aerodynamic diameter (PM_2.5). However, relatively few epidemiologic studies focus on the health impacts of wildfire smoke PM_2.5 compared with the number of studies focusing on total PM_2.5 exposure.

Objectives

We estimated the associations between cardiorespiratory acute events and exposure to smoke PM_2.5 in Colorado using a novel exposure model to separate smoke PM_2.5 from background ambient PM_2.5 levels.

Methods

We obtained emergency department visits and hospitalizations for acute cardiorespiratory outcomes from Colo
