在发展中国家，传统生物质炉灶使用的固体燃料造成的室内空气污染是造成呼吸系统健康状况不佳、全球疾病负担和温室污染物排放的主要因素。在本研究中，我们对云南省西北部丽江和德钦县农村的30户家庭进行了实验性的横断面监测和评估设计。这种方法提供了以更小的样本量来检查改进炉灶（ICS）计划的有效性的能力，而不是典型的基于人群的干预前和干预后研究，需要一个具有代表性的大样本。使用UCB（目前称为UCB- pats）和TSI DustTrak测量连续PM2.5，使用HOBO CO记录仪测量连续CO。使用传统的烹饪和加热方法，意味着24小时PM2.5在厨房和CO浓度测量范围在0.15 - -0.71毫克为PM2.5和3.0米(3)浓度-11 ppm有限公司这些比较使用的组合改进炉具在厨房PM2.5和CO浓度的测量范围在0.08 - -0.18毫克m为PM2.5和0.7 - -5.5 ppm(3)有限公司这些浓度产生显著减少IAP当替换传统的壁炉或传统的炉子和一种改进的炉子组合。最后，我们显示CO和PM2.5之间存在很强的相关性（R-2 = 0.72-0.76）。该实验设计与本文提出的监测和评估方案相结合，可以提供一个强大的框架，以快速评估正在进行的ICS干预措施的有效性。(C) 2012 Elsevier Ltd.版权所有。
In the developing world, indoor air pollution (IAP) created from solid fuel used in traditional biomass cook stoves is a leading contributor of poor respiratory health, global burden of disease, and greenhouse pollutant emissions. In the present study, we piloted an experimental cross-sectional monitoring and evaluation design with 30 households in rural Lijiang and Deqin counties in northwest Yunnan province, China. This approach offers the ability to examine the effectiveness of improved cook stove (ICS) programs with a much smaller sample size than the typical population based pre- and post-intervention study that requires a large sample representative of the population. Continuous PM2.5 was measured with the UCB (currently known as UCB-PATS) and the TSI DustTrak and continuous CO was measured with the HOBO CO logger. Using the traditional method of cooking and heating, mean 24-h PM2.5 and CO concentrations in the kitchen were measured in the range of 0.15-0.71 mg m(-3) for PM2.5 and 3.0-11 ppm for CO. These concentrations were compared to using a combination of improved stoves in the kitchen where PM2.5 and CO concentrations were measured in the range of 0.08-0.18 mg m(-3) for PM2.5 and 0.7-5.5 ppm for CO. These concentrations yielded statistically significant reduction in IAP when replacing the traditional fireplace or traditional stove with an improved stove combination. Finally, we show a strong correlation between CO and PM2.5 (R-2 = 0.72-0.76). The combination of this experimental design along with the monitoring and evaluation protocol presented here may provide a robust framework to rapidly assess the effectiveness of ICS interventions in progress.
