Third-hand smoke (THS) is a new cigarette-related issue defined as the residual contamination from cigarette smoke after a cigarette is extinguished. To detect THS on three commonly used clothing fibers-wool, cotton, and polyester, we applied two methods to measure the adsorption of THS: one was the gain of mass with an analytical balance after exposure to cigarette smoke; and the other was to detect the THS chemical compounds such as nicotine and 3-ethenylpyridine with a surface acoustic wave (SAW) sensor composed of coated oxidized hollow mesoporous carbon nanospheres. In the mass measurement, the gain of mass decreased in the order wool, cotton, and polyester; the latter gain was about one tenth that of wool. In the SAW detection, the frequency shift decreased in the same order-wool, cotton, and polyester. The residence period of THS on natural fiber (wool and cotton) is greater than on synthetic polyester fiber. These two tests provide quantitative results of THS on varied clothing fibers, to assess their risk after exposure to cigarette smoke.
三手烟（THS）是一个与香烟相关的新问题，被定义为香烟熄灭后烟雾的残留污染物。为了检测三种常用服装纤维（羊毛、棉花和聚酯）上的三手烟，我们应用了两种方法来测量三手烟的吸附情况：一种是在暴露于香烟烟雾后用分析天平测量质量增加；另一种是用由涂覆有氧化中空介孔碳纳米球的表面声波（SAW）传感器检测尼古丁和3-乙烯基吡啶等三手烟化合物。在质量测量中，质量增加量按羊毛、棉花和聚酯的顺序递减；后者的增加量约为羊毛的十分之一。在表面声波检测中，频率偏移也按相同顺序（羊毛、棉花和聚酯）递减。三手烟在天然纤维（羊毛和棉花）上的停留时间比在合成聚酯纤维上更长。这两项测试提供了三手烟在不同服装纤维上的定量结果，以评估它们在接触香烟烟雾后的风险。
