%T Quantifying the Potential Health Impacts of Unvented Combustion in Homes – A Meta-Analysis
%8 10/2023
%X <p>While a growing body of scientific literature describes the population health impacts of fossil fuel<br />production and burning via climate and air pollution pathways, less is known about the health<br />impacts of indoor combustion. This paper summarizes the results of studies from the last two<br />decades that investigated the association between exposure to sources of unvented combustion<br />pollutants in homes and a range of health outcomes. We found gas combustion to be associated<br />with 6-28% (95% confidence intervals) increased odds of asthma symptoms, 4-51% increased<br />odds of systemic symptoms, 7-81% increased odds of asthma medication use, and 3-12%<br />increased risk of mortality. These findings can be used to improve public health, for example, by<br />informing requirements for improved ventilation and source control, justifying switching to vented<br />appliances, better regulation of device emissions and quantifying the benefits of electrification<br />of end-uses. Dose-response relationships between human health, NO 2 exposure, and other by-<br />products of combustion are not characterized with a high degree of precision. However, there is<br />clear evidence of a wide range of health effects, even at low levels of exposure. Despite the<br />various designs, geographic sites, length of follow-up, and study dates, we noted a level of<br />consistency between the studies within the current meta-analysis, and with previous ones, which<br />strengthens the level of confidence in our findings.</p>
