title: Residential exposures to PM2.5 and CO in Cusco, a high-altitude city in the Peruvian Andes: a pilot study.
abstract: High-altitude populations using biofuels for household energy may be at health risk due to a combination of altitudinal stress and indoor exposures to biomass smoke. In this article, the authors measure indoor and outdoor breathing level concentrations of PM(2.5) and CO during periods of meal preparation in a convenience sample of homes above 3000 m in Cusco, Peru. From July 10 to 21, 2005, 237 measurements were taken during a pilot study at 41 residences. Results show the highest levels of PM(2.5) and CO occurred during the early morning in the kitchen when dung and wood were used. Additionally, findings suggest that residential biomass fuel combustion in Cusco results in elevated indoor PM(2.5) and CO exposure levels that are of potential human health concern, an issue that may be exacerbated by the physiological impact of living in a high-altitude environment.
