The objective of this study was to measure secondhand smoke (SHS) exposure in personal computer (PC) rooms with the purpose of determining the strength of scientific evidence supporting the legislative ban on smoking in PC rooms located in the Republic of Korea.
From June to September 2012, particulate matter (PM2.5) and air nicotine concentration (ANC) were measured in the smoking and non-smoking areas of PC rooms in Goyang City, Korea. In 28 randomly sampled PC rooms, field investigators completed an observational questionnaire on building characteristics, smoking policies, and evidence of smoking. The geometric means (GM) of PM2.5 and ANC in smoking and non-smoking areas were compared.
Evidence of smoking was identified in both the smoking and non-smoking areas of all PC rooms. The GMs of PM2.5 and ANC in both areas were high and did not differ significantly (174.77 μg/m(3) and 48.95 μg/m(3) in smoking areas; 93.38 μg/m(3) and 41.30 μg/m(3) in non-smoking areas). Overall PM2.5 concentrations were 5.5-fold higher than those listed in the World Health Organization guidelines.
This study supported previous reports that a partial smoking ban did not protect individuals from SHS exposure. Furthermore, the results from our study suggest how research can support policy. Countries in which smoke-free policies are not yet comprehensive may find our results useful.
本研究旨在测量个人电脑（PC）室内的二手烟（SHS）暴露水平，以确定支持韩国禁止在 PC 室内吸烟的立法的科学证据的力度。
2012 年 6 月至 9 月，在韩国高阳市的 PC 室内的吸烟区和非吸烟区测量了颗粒物（PM2.5）和空气尼古丁浓度（ANC）。在 28 个随机抽样的 PC 室内，现场调查员完成了一份关于建筑特征、吸烟政策和吸烟证据的观察性问卷。比较了吸烟区和非吸烟区的 PM2.5 和 ANC 的几何平均值（GM）。
所有 PC 室内的吸烟区和非吸烟区均发现有吸烟证据。两个区域的 PM2.5 和 ANC 的 GM 均较高，且无显著差异（吸烟区分别为 174.77μg/m3 和 48.95μg/m3；非吸烟区分别为 93.38μg/m3 和 41.30μg/m3）。总体 PM2.5 浓度是世界卫生组织指南中列出的浓度的 5.5 倍。
本研究支持了之前的报告，即部分禁烟并不能保护个人免受 SHS 暴露。此外，我们的研究结果还表明了研究如何支持政策。尚未全面实施无烟政策的国家可能会发现我们的研究结果很有用。
