吸烟是室内环境中颗粒物释放的主要来源。一项关于香烟和香烟烟雾中元素分布的综合研究已经完成。具体来说，已经确定了15种香烟成分中30种元素的浓度。成分包括烟草、烟灰、烟头、过滤嘴和卷烟纸。此外，还对主流烟雾（MS）和侧流烟雾（SS）中的颗粒物进行了分析。本研究采用的元素测定技术是仪器中子活化分析。？结果表明，某些重金属，如砷、镉、锑和锌，被释放到MS和SS中，这些金属可能是暴露在烟雾中的健康风险的一部分。其他元素大部分保留在烟灰和烟头中。在不同的吸烟条件下，香烟成分和烟雾中的元素分布是不同的。
Cigarette smoking is a major source of particles released in indoor environments. A comprehensive study of the elemental distribution in cigarettes and cigarette smoke has been completed. Specifically, concentrations of thirty elements have been determined for the components of 15 types of cigarettes. Components include tobacco, ash, butts, filters, and cigarette paper. In addition, particulate matter from mainstream smoke (MS) and sidestream smoke (SS) were analyzed. The technique of elemental determination used in the study is instrumental neutron activation analysis. ?he results show that certain heavy metals, such as As, Cd, Y Sb and Zn, are released into the MS and SS. These metals may then be part of the health risk of exposure to smoke. Other elements are retained, for the most part, in cigarette ash and butts. The elemental distribution among the cigarette components and smoke changes for different smoking conditions.
