The purpose of this study was to check a simple sampling and easy gas analysis of tobacco smoke for effective tobacco intervention in medical education.
The mainstream of tobacco smoke was sampled by a syringe (50 ml) at five, ten and twenty seconds. The extracted mainstream was moved to a commercial PET bottle (2000 ml), and measured with gas detector tubes. The sidestream, which rises from the tip of the cigarette, was collected into a commercial PET bottle for a duration of 30 or 60 seconds. Formaldehyde, acetaldehyde, ammonia, hydrogen cyanide, and nitrogen oxides (NO, NO2) in the tobacco smoke were measured. Then, these gasses in the tobacco smoke of four brands of cigarettes were compared. This trial was conducted in third-year medical students, and the changes in attitudes to smokers and tobacco itself were investigated.
The method of sampling 50 ml for 5 seconds produced the highest concentration of each gas in the mainstream. The gas concentration in the sidestream increased as the sampling time increased. The gas concentration in mainstream of "Lucia" was the highest of the used four brands, and the gas concentrations in the sidestream of "Mild Seven Prime" were higher than those of the other brands. Many medical students obtained knowledge about the toxicity of smoking by this experiment study.
We studied a simple sampling method of tobacco smoke, and gas analysis with gas detector tubes. This method is recommended for tobacco education and intervention in medical education.
本研究旨在检验一种简单的烟草烟雾采样和便捷的气体分析方法，以便在医学教育中进行有效的烟草干预。
用注射器（50毫升）在5秒、10秒和20秒时采集烟草主流烟雾。将采集到的主流烟雾转移到一个商用PET瓶（2000毫升）中，并用气体检测管进行测量。从香烟顶端升起的侧流烟雾被收集到一个商用PET瓶中，持续30或60秒。测量烟草烟雾中的甲醛、乙醛、氨、氰化氢和氮氧化物（NO、NO2）。然后，比较四个品牌香烟的烟草烟雾中的这些气体。该试验在三年级医学生中进行，并调查他们对吸烟者和烟草本身态度的变化。
5秒采集50毫升的方法在主流烟雾中产生的每种气体浓度最高。侧流烟雾中的气体浓度随着采样时间的增加而增加。在所用的四个品牌中，“露西亚”香烟主流烟雾中的气体浓度最高，“柔和七星原味”香烟侧流烟雾中的气体浓度高于其他品牌。许多医学生通过本实验研究获得了吸烟毒性的知识。
我们研究了一种简单的烟草烟雾采样方法以及用气体检测管进行气体分析的方法。该方法推荐用于医学教育中的烟草教育和干预。
