这项研究的目的是评估在依赖木材燃料的危地马拉农村人口中，改进的炉灶、房屋通风和儿童位置对室内空气污染水平和儿童暴露的影响。这项研究是从危地马拉西部高地一个农村的204个孩子不到18个月的家庭中随机抽取的。通过访谈和观察获得社会经济和家庭信息。使用Gastec扩散管，24小时一氧化碳(CO)被用作所有家庭厨房污染和儿童暴露的主要衡量标准。24小时厨房PM3.5是在一个随机的子样本(n=29)中测量的，厨房里有CO管。几乎50%的房屋仍在使用中。大约30%的家庭使用烟囱炉灶(Plchas)，主要来自一个大型捐赠者资助的项目，其余的家庭使用各种组合，包括瓶装天然气和开放式。瑞斯。24小时厨房CO最低的是有自购Plchas的家庭：平均(95%CI)CO为3.09ppm(1.87-4.30)，而开放式为12.4ppm(10.2-14.5)。瑞斯。在儿童一氧化碳暴露中发现了相同的排名，但比例差异较小(P
The goal of this study was to assess the impact of improved stoves, house ventilation, and child location on levels of indoor air pollution and child exposure in a rural Guatemalan population reliant on wood fuel. The study was a random sample of 204 households with children less than 18 months in a rural village in the western highlands of Guatemala. Socio-economic and household information was obtained by interview and observation. Twenty-four hour carbon monoxide (CO) was used as the primary measure of kitchen pollution and child exposure in all homes, using Gastec diffusion tubes. Twenty-four hour kitchen PM3.5 was measured in a random sub-sample (n = 29) of kitchens with co-located CO tubes. Almost 50% of the homes still used open. res, around 30% used chimney stoves (planchas) mostly from a large donor-funded programme, and the remainder of homes used various combinations including bottled gas and open. res. The 24-h kitchen CO was lowest for homes with self-purchased planchas: mean (95% CI) CO of 3.09 ppm (1.87-4.30) vs. 12.4 ppm (10.2-14.5) for open. res. The same ranking was found for child CO exposure, but with proportionately smaller differentials (P
