The impact of cigarette smoking on the distribution of organic substances in ambient air has been determined for the intermediate volatility range. A simple sampling procedure was employed, involving gas-solid adsorption onto an organic polymer followed by direct thermal elution onto a glass capillary column. Aliphatic and substituted aromatic hydrocarbons are predominant in urban atmospheres. Depending on location and weather conditions the total concentration of such volatiles can differ by as much as a factor of 20. This high background variation makes it difficult to analyze for trace substances with low odor threshold values, such as encountered in cigarette smoke. Standard cigarettes were smoked in a relatively small room, having no air filtration system. Air samples of approximately 3.51 were taken. The amount of volatiles added to air by cigarette smoking is unsignificant. Substances were analyzed and identified by gas chromatography and gas chromatography-mass spectrometry with glass capillary columns. Many compounds reported in cigarette smoke condensate have been confirmed.
已经确定了吸烟对中等挥发性范围内环境空气中有机物质分布的影响。采用了一种简单的采样程序，包括将气体-固体吸附到有机聚合物上，然后直接热洗脱到玻璃毛细管柱上。脂肪族和取代芳烃在城市大气中占主导地位。根据位置和天气条件，此类挥发性物质的总浓度相差可达20倍。这种高背景变化使得难以分析具有低气味阈值的痕量物质，例如香烟烟雾中遇到的物质。在一个相对较小且没有空气过滤系统的房间里吸标准香烟。采集了约3.5升的空气样本。吸烟添加到空气中的挥发性物质的量微不足道。通过使用玻璃毛细管柱的气相色谱和气相色谱-质谱对物质进行分析和鉴定。香烟烟雾冷凝物中报告的许多化合物已得到证实。
