【摘要】 为客观评价室内环保吸烟室中抽吸卷烟对周围空气质量的影响，建立了卷烟环境烟草烟气（ETS）污染物分析方法体系，包含CO、PM_2.5等13种室内空气质量指标和烟碱等3种ETS标志物指标。考察了室内环保吸烟室在不同空气交换率（低、中、高）时，吸烟室中（测试时，2名志愿者各抽吸1支卷烟）、出风口处、门口处、门外1 m处、门外3 m处及非吸烟区空气污染物浓度的差异。结果表明：（1）所建立的离线分析方法效果良好，适用于卷烟ETS污染物的定量分析。（2）与风机不开（低空气交换率）相比，室内环保吸烟室在中、高空气交换率时，CO、PM_2.5等13种空气质量指标浓度均显著降低，且所有采样点处13种空气质量指标的浓度均低于室内空气限量值；3种卷烟ETS标志物浓度均显著降低，所有采样点均未检出茄尼醇，仅吸烟室中能检测到烟碱和3-乙烯基吡啶。（3）中、高空气交换率时，除CO（降低率约为77.00%）外，室内环保吸烟室中空气质量指标和ETS标志物浓度降低率均大于等于93.00%。因此，室内环保吸烟室在正常维护保养情况下，抽吸卷烟对周围空气质量的影响较小。更多还原

【Abstract】 In order to objectively evaluate the influence of cigarette smoking on the air quality in an indoor environmentally friendly smoking room, an analytical method system for environmental tobacco smoke（ETS）pollutants was established, including 13 indoor air quality indexes such as CO,PM_2.5, and 3 ETS markers such as nicotine. At different air exchange rates（i.e., low, medium, and high） of the smoking room, the influences of smoking on the concentration of air pollutants at the inside（two volunteers smoked one cigarette each during the test）, air outlet of the smoking room,door, outside 1 m, outside 3 m, and non-smoking area were investigated. The results showed that:1)The established offline analytical methods performed well and were suitable for quantitative analysis of ETS pollutants. 2) Compared to the condition where the extraction fan was not turned on（low air exchange rate）, indoor air quality indexes such as CO, PM_2.5 significantly decreased at the medium and high air exchange rates of the smoking room, causing them to fall below the indoor air limit at all sampling points. Concentrations of the three ETS markers also decreased significantly. Solanesol was not detected at all sampling locations, while nicotine and 3-vinylpyridine were detected only in the smoking room. 3) At the medium and high air exchange rates, the reduction rates of all the indoor air quality indexes and ETS markers were equal to or greater than 93.00%, except for CO（approximately 77.00%）. Therefore, smoking in an indoor environmentally friendly smoking room with normal maintenance had a minimal effect on the indoor air quality.更多还原
