卷烟侧流烟气中有害醛酮类化合物的分析

摘要

In order to determine the harmful aldehyde and ketone compounds in sidestream cigarette smoke, the influences of each part of trapping device and sample preparation on the determined values of eight aldehyde and ketone compounds were investigated. A method involving trapping, preparing, and determining with high performance liquid chromatography was developed, and the deliveries of eight aldehyde and ketone compounds in sidestream cigarette smoke of 21 samples of domestic and imported commercial available cigarettes were detected. The results showed that the total content of the eight compounds was in the range of 3300 to 4600 (μg per cigarette (μg/cig.), in which the content of acetaldehyde was the highest (1600 to 2300 (μg/ cig.), followed by formaldehyde and acetone (400 to 800 μg/cig.), and the others were within 70 to 250 μg/cig.%为了测定卷烟侧流烟气中的有害醛酮类化合物,考察了卷烟侧流烟气捕集装置各部分对8种有害醛酮的捕集量和样品处理方法对其测定量的影响,建立了捕集、处理及高效液相色谱法检测卷烟侧流烟气中8种有害醛酮类的方法,并采用该方法测定了市售国内外21种卷烟样品侧流烟气中这8种有害醛酮的释放量.结果表明:所测卷烟样品侧流烟气中8种醛酮的总释放量在3300～4600 μg/支之间.其中,乙醛释放量最高,在1600～2300 μg/支之间；丙酮和甲醛次之,释放量在400～800 μg/支之间；而其他5种醛酮的释放量在70～250 μg/支之间.
