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.
由于海拔压力以及室内生物质烟雾暴露的综合影响，使用生物燃料作为家庭能源的高海拔人群可能面临健康风险。在本文中，作者在秘鲁库斯科海拔3000米以上的家庭便利样本中，测量了做饭期间室内和室外呼吸水平的细颗粒物（PM2.5）和一氧化碳（CO）浓度。2005年7月10日至21日，在41处住宅进行的一项初步研究中进行了237次测量。结果显示，使用粪便和木材时，厨房内清晨的细颗粒物（PM2.5）和一氧化碳（CO）水平最高。此外，研究结果表明，库斯科住宅生物质燃料燃烧导致室内细颗粒物（PM2.5）和一氧化碳（CO）暴露水平升高，这可能对人类健康构成潜在威胁，而生活在高海拔环境中的生理影响可能会加剧这一问题。
