用聚合物填充的样品制备针和随后的气相色谱-质谱分析定量评估三手吸烟。以聚合物颗粒为萃取介质制备了萃取针，并成功地实现了对典型气态挥发性有机化合物（VOCs）的萃取。为了评估这种新的香烟危害，几种类型的服装织物暴露于侧流烟雾，和吸烟相关的挥发性有机化合物从织物蒸发到环境空气中的萃取针进行预浓缩。同时，利用抽气针测定了吸烟者呼吸中与吸烟相关的VOCs，并评价了呼吸VOCs对三手烟污染的影响。结果表明，该方法可成功地测定痕量与吸烟有关的挥发性有机物。不同织物材料对与吸烟相关的VOCs的吸附和解吸行为存在明显差异，并定量评价了这些VOCs浓度的时间变化。吸烟者呼吸中的VOCs明显高于非吸烟者;但结果表明，在典型的生活空间中，吸烟者的呼吸对潜在的污染没有显著影响。将该方法应用于汽车内实际三手烟污染的测定，并对该方法在环境空气中痕量VOCs分析中的应用前景进行了展望。
Third-hand smoking was quantitatively evaluated with a polymer-packed sample preparation needle and subsequent gas chromatography-mass spectroscopy analysis. The extraction needle was prepared with polymeric particles as the extraction medium, and successful extraction of typical gaseous volatile organic compounds (VOCs) was accomplished with the extraction needle. For an evaluation of this new cigarette hazard, several types of clothing fabrics were exposed to sidestream smoke, and the smoking-related VOCs evaporated from the fabrics to the environmental air were preconcentrated with the extraction needle. Smoking-related VOCs in smokers’ breath were also measured using the extraction needle, and the effect of the breath VOCs on third-hand smoking pollution was evaluated. The results demonstrated that a trace amount of smoking-related VOCs was successfully determined by the proposed method. The adsorption and desorption behaviors of smoking-related VOCs were clearly different for each fabric material, and the time variations of these VOCs concentrations were quantitatively evaluated. The VOCs in the smokers’ breath were clearly higher than that of nonsmokers’; however, the results suggested that no significant effect of the smokers’ breath on the potential pollution occurred in the typical life space. The method was further applied to the determination of the actual third-hand smoking pollution in an automobile, and a future possibility of the proposed method to the analysis of trace amounts of VOCs in environmental air samples was suggested.
