本文报道了在中国农村肺癌流行区，烟囱在减少室内空气污染方面的作用。在宣威，中国家庭室内空气污染浓度进行了测量，在不通风燃烧（烟囱堵塞）和通风燃烧（烟囱打开）的烟煤。空气动力学直径为10 μ m或更小的颗粒物（PM10）和苯并[a]芘（BaP）的浓度进行了测量，在43个家庭在正常活动。烟囱的使用使室内空气中空气动力学直径为10微米或以下的颗粒物（PM10）浓度显着降低了66%，苯并[a]芘（BaP）浓度显着降低了84%。安装烟囱后，PM10中苯并（a）芘的平均含量也降低了55%。通过安装烟囱减少室内污染水平支持了关于改进炉灶对健康有益的流行病学调查结果。然而，即使有烟囱，室内空气中PM10和BaP的浓度仍然超过了中国的室内空气质量标准。在能源阶梯上向更清洁的液体或气体燃料移动可能是唯一可持续的室内空气污染控制措施。(C)2009爱思唯尔有限公司保留所有权利。
This paper reports the effect of chimneys in reducing indoor air pollution in a lung cancer epidemic area of rural China. Household indoor air pollution concentrations were measured during unvented burning (chimneys blocked) and vented burning (chimneys open) of bituminous coal in Xuan Wei, China. Concentrations of particulate matter with an aerodynamic diameter of 10 mu m or less (PM10) and of benzo[a]pyrene (BaP) were measured in 43 homes during normal activities. The use of chimneys led to significant decreases in indoor air concentrations of particulate matter with an aerodynamic diameter of 10 mu m or less (PM10) by 66% and of benzo[a]pyrene (BaP) by 84%. The average BaP content of PM10 also decreased by 55% with the installation of a chimney. The reduction of indoor pollution levels by the installation of a chimney supports the epidemiology findings on the health benefits of stove improvement. However, even in the presence of a chimney, the indoor air concentrations for both PM10 and BaP still exceeded the indoor air quality standards of China. Movement up the energy ladder to cleaner liquid or gaseous fuels is probably the only sustainable indoor air pollution control measure. (C) 2009 Elsevier Ltd. All rights reserved.
