摘要
香烟燃烧的主动吸烟、呼出烟雾、自由燃烧3种排放方式中,对一氧化碳CO、总挥发性有机物TVOC进行测定分析。自由燃烧模式较主动吸烟模式造成的CO和TVOC污染更高。对于室内环境的污染和被动吸烟者的危害,自由燃烧模式与呼出烟气模式的贡献比例CO和TVOC分别约为15/1和4/1。主动吸烟者吸入的烟气中CO和TVOC浓度可分别高达约10000mg/m3和800mg/m3,高出国家室内空气环境标准限量约1000倍,吸入的烟气中约有40%的CO通过肺部被人体吸收。
Carbon monoxide (CO) and total volatile organic compound (TVOC) were qualitatively analyzed in the different release patterns of burning cigarette inchiding initiative inhaling smoke, exhaled smoke and no inhaling smoke. The CO and TVOC are produced much more in no inhaling smoke than that in initiative inhaling smoke. The one cigarette polluting proportion of no inhaling smoke to exhaled smoke is 15:1 for CO and 4:1 for TVOC. During initiative inhaling smoke, the approximate concentration of CO and TVOC are high to 10000 mg/m3 and 800 mg/m3 respectively, 1000 times more than the government standard limit. Approximately 40% inhaled CO is absorbed by lung via one inhaling and exhaling smoke process.
