在亚洲，在房屋和寺庙中烧香进行宗教活动尤其普遍。焚香产生的烟雾是室内气溶胶的来源，这种烟雾的提取物在艾姆斯沙门氏菌试验中具有致突变性。本文描述了烟雾的颗粒大小，形状，浓度，密度和化学成分方面的表征。我们的数据显示，熏香烟雾中的气溶胶是球形液滴，计数中位直径约为0.13 μ m，质量中位空气动力学直径为0.28 μ m。颗粒密度为1.06 +/- 0.08 g cm（-3）。因此，熏香产生的气溶胶类似于冷凝形成的其他气溶胶，例如室内发现的环境烟草烟雾。在典型的燃烧周期的房间内的气溶胶浓度分布和尺寸分布进行了监测。用SF6示踪气体法测定了室内空气通风量。可吸入气溶胶浓度高达几百μ g m（-3），通过燃烧一到三个香。通过使用数学方程对房间中的浓度随时间的变化进行建模，我们估计了作为时间的函数的香气溶胶产生速率和气溶胶去除速率常数。此源项信息可用于估计室内环境中的熏香烟雾浓度。
Burning incense in houses and temples for religious functions is especially common in Asia. Smoke from burning incense is a source of indoor aerosols, and extracts from this smoke are mutagenic in the Ames Salmonella test. This paper describes characterization of the smoke in terms of particle size, shape, concentration, density, and chemical composition. Our data showed that aerosols from incense smoke were spherical droplets with a count median diameter of about 0.13 mu m and mass median aerodynamic diameter of 0.28 mu m. The particle density was 1.06 +/- 0.08 g cm(-3). Aerosols produced from incense are therefore similar to other aerosols formed by condensation, such as environmental tobacco smoke found indoors. The aerosol concentration profiles and size distributions within a room during typical burning cycles were monitored. The air ventilation rate in the room was also measured by the SF6 tracer gas method. Respirable aerosol concentrations up to several hundred mu g m(-3) were produced by burning one to three joss sticks. By modeling the concentration change in the room with time using mathematical equations, we estimated the incense aerosol generation rate as a function of time and the aerosol removal rate constant. This source term information can be used to estimate incense smoke concentration in indoor environments.
