摘要

Household heating using wood stoves is common practice in many rural areas of theUnited States (US) and can lead to elevated concentrations of indoor fine particulatematter (PM_(2.5)). We collected 6-daymeasures of indoor PM_(2.5) during the winter andevaluated household and stove-usecharacteristics in homes at three rural and diversestudy sites. The median indoor PM_(2.5) concentration across all homes was 19 μg/m~3,with higher concentrations in Alaska (median = 30, minimum = 4, maximum = 200,n = 10) and Navajo Nation homes (median = 29, minimum = 3, maximum = 105, n = 23)compared with Montana homes (median = 16, minimum = 2, maximum = 139, n = 59).Households that had not cleaned the chimney within the past year had 65% highergeometric mean PM_(2.5) compared to those with chimney cleaned within 6 months(95% confidence interval [CI]: −1, 170). Based on a novel wood stove grading method,homes with low-quality and medium-qualitystoves had substantially higher PM_(2.5) compared to homes with higher-qualitystoves (186% higher [95% CI: 32, 519] and161% higher; [95% CI:27, 434], respectively). Our findings highlight the need for, andcomplex nature of, regionally appropriate interventions to reduce indoor air pollutionin rural wood-burningregions. Higher-qualitystoves and behavioral practices such asregular chimney cleaning may help improve indoor air quality in such homes.
