Abstract

South Korea was the first to administer the Indoor Air Quality Control Act in 1996, followed by Taiwan’s implementation in 2012. This study investigated indoor air quality (IAQ) in public facilities before and after the enactment of Taiwan’s Indoor Air Quality Management (IAQM) Act in 2012 to assess the effectiveness of the Act. The study also calculates health risks for employers, and consumers/visitors separately. The mean concentration of carbon dioxide (CO2) after the IAQM Act’s enactment was higher than before, except for government offices. The lowest attainment rates for CO2, below 80%, were 73% in hospitals and 78% in libraries. As for formaldehyde, average concentrations were higher after the IAQM Act’s implementation, except for the exhibition room and library. Notably, improvements in particulate matter with a diameter less than 2.5 μm (PM2.5) levels were evident in hospitals and libraries compared to other environments (attainment rates increased from 85% to 100% and 89% to 94%, respectively). However, in schools, preschools, and public transport spaces, unattainment rates worsened. Regarding cancer risk from formaldehyde exposure in the public, the 95% of upper risk limits ranged from 3.44 × 10−5 in the public transport system to 8.80 × 10−4 in preschools. Our findings highlight the necessity of integrating more measurement data after IAQM Act implementation and formulating management strategies based on risk assessments for future investigations.

台湾《室内空气质量管理法》颁布前后公共设施室内空气质量的变化
韩国于 1996 年率先实施《室内空气质量管理法》,台湾随后于 2012 年开始实施。本研究调查了 2012 年台湾《室内空气质量管理法》颁布前后公共设施的室内空气质量,以评估该法的有效性。研究还分别计算了雇主和消费者/访客的健康风险。室内空气质量管理法》颁布后,除政府办公室外,二氧化碳(CO2)的平均浓度均高于颁布前。二氧化碳的最低达标率(低于 80%)是医院的 73%和图书馆的 78%。至于甲醛,除展览室和图书馆外,《室内空气质量管理法》实施后的平均浓度都较高。值得注意的是,与其他环境相比,医院和图书馆在直径小于 2.5 μm 的颗粒物(PM2.5)水平方面有明显改善(达标率分别从 85% 提高到 100%,从 89% 提高到 94%)。然而,在学校、幼儿园和公共交通场所,未达标率有所恶化。关于公众接触甲醛致癌的风险,风险上限的 95% 范围从公共交通系统的 3.44 × 10-5 到学龄前学校的 8.80 × 10-4。我们的研究结果突出表明,在《室内空气质量管理法》实施后,有必要整合更多的测量数据,并在风险评估的基础上制定管理策略,以供今后的调查使用。

期刊介绍: The quality of the environment within buildings is a topic of major importance for public health. Indoor Air provides a location for reporting original research results in the broad area defined by the indoor environment of non-industrial buildings. An international journal with multidisciplinary content, Indoor Air publishes papers reflecting the broad categories of interest in this field: health effects; thermal comfort; monitoring and modelling; source characterization; ventilation and other environmental control techniques. The research results present the basic information to allow designers, building owners, and operators to provide a healthy and comfortable environment for building occupants, as well as giving medical practitioners information on how to deal with illnesses related to the indoor environment.
