Particulate Matter (PM) is a well-known health risk factor and pollutes both outdoor and indoor air. Using PM as an air pollution indicator, the aims were to assess outdoor and indoor air pollution due to combustion and/or non-combustion products used outdoors and to compare the PM levels emitted by different products. PM with an aerodynamic diameter ≤10, 4, 2.5 and 1 µm (PM, PM, PM, PM) was simultaneously measured in two areas, respectively, indoors (with smoking ban) and outdoors (where people commonly smoke) of a university library during the morning and the afternoon of two weekdays. Both combustion and non-combustion products determined a relevant worsening of outdoor air quality, with the highest PM levels achieved when a single traditional cigarette (9920 µg m), a single e-cigarette (9810 µg m) and three simultaneous traditional cigarettes (8700 µg m) were smoked. An increase of indoor PM levels was found during outdoor smoking/vaping sessions, persisting also after the end of sessions. The results highlighted the need for a revision of smoke-free laws, especially for outdoor areas, to include non-combustion products. In addition, it is essential to make society aware of the dangers of smoking outdoors by implementing health promotion interventions.
颗粒物（PM）是一种众所周知的健康风险因素，会污染室外和室内空气。本研究使用 PM 作为空气污染指标，旨在评估因室外燃烧和/或非燃烧产品使用而导致的室外和室内空气污染，并比较不同产品排放的 PM 水平。在两个工作日的上午和下午，分别在大学图书馆的室内（禁烟）和室外（人们通常吸烟的地方）同时测量空气动力学直径≤10、4、2.5 和 1 µm（PM、PM、PM、PM）的颗粒物。燃烧和非燃烧产品均显著恶化了室外空气质量，当单支传统香烟（9920 µg m）、单支电子烟（9810 µg m）和同时点燃三支传统香烟（8700 µg m）时，PM 浓度达到最高值。在室外吸烟/蒸汽时，室内 PM 水平也会升高，并且在吸烟/蒸汽结束后仍会持续升高。研究结果强调需要修订禁烟法，特别是针对室外区域，将非燃烧产品纳入禁烟范围。此外，还必须通过实施健康促进干预措施，使社会认识到在户外吸烟的危害。
