摘要

生物气溶胶,包括空气传播的细菌和真菌,广泛分布在室内环境中,对人体健康造成不利影响。在首都圈的12个设施中,对政府分类的6种公共室内场所的悬浮物进行了调查。共有245个样本提供了除居住者人数外与室内湿度密切相关的证据。托儿中心生物气溶胶浓度较高(26 CFU/m3 ~ 2916 CFU/m3),暴露风险为120.2 CFU/kg。室内生物气溶胶水平以夏季居多,冬季居多。本研究结果为城市公共空间的空气质量管理和微生物污染控制提供了有价值的信息。影响和影响——公共室内空间的生物污染正引起人们的关注,尤其是在大城市。−现场识别生物气溶胶水平有助于制定预防政策。−现场数据的持续积累是改善室内环境的必要条件。

Environmental investigation of the quantitative distribution of bioaerosols in public indoor spaces – A case study in Korea
Bioaerosols, including airborne bacteria and fungi, are widely distributed in the indoor environments causing adverse effects on human health. Bioaerosols suspended in six types of public indoor spaces categorized by the government were investigated in 12 facilities in a large metropolitan area of Korea. A total of 245 samples provided evidence of a close dependency on indoor humidity in addition to the numbers of occupants. Childcare centers had high concentrations of bioaerosols (26 CFU/m3 to 2916 CFU/m3), indicating high risk of exposure with 120.2 CFU/kg. The indoor bioaerosol level was high mostly in summer rather than winter. The results of this study provide valuable information on air quality management and microbial pollution control in urban public spaces.

Implications and impacts

  • Bio-contamination of public indoor spaces is being of interests particularly in metro-cities.
  • Field identification of bioaerosol levels will help in establishing the preventive policy.
  • Consistent accumulation of field data is essential for improving the indoor environment.
