This study conducted an exposure assessment for office workers in Korea. Indoor and outdoor air pollutants were measured in offices. A self-administered questionnaire was employed to determine work information, indoor air quality (IAQ) awareness, and subjective symptoms for 328 workers. Indoor air concentrations for measured air pollutants were below IAQ guideline values. The average concentrations of target air pollutants did not show significant differences except for benzene, which had relatively a higher concentration in national industrial complexes. The indoor benzene, ethylbenzene, and acetaldehyde concentrations were higher in offices where workers were having dry eye, ophthalmitis, and headache symptoms. This study provides reference values to manage IAQ in offices, suggesting that if the benzene concentration exceeds 4.23 \u03bcg\/m3 in offices, it could cause dry eye symptoms. Considering the increasing working hours for office workers and health effects, workers\u2019 exposure to indoor pollutants should be reduced. In addition, the IAQ was heavily influenced by outdoor air levels and various indoor sources. Therefore, in areas with relatively high air pollution, greater monitoring and management is required considering the influence of outdoor air quality.<\/jats:p>","DOI":"10.3390\/ijerph19042446","type":"journal-article","created":{"date-parts":[[2022,2,21]],"date-time":"2022-02-21T08:18:05Z","timestamp":1645431485000},"page":"2446","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Risk Assessment of Indoor Air Quality and Its Association with Subjective Symptoms among Office Workers in Korea"],"prefix":"10.3390","volume":"19","author":[{"given":"Dayoung","family":"Jung","sequence":"first","affiliation":[{"name":"Department of Occupational Health, Daegu Catholic University, Gyeongsan 42472, Korea"},{"name":"Environmental Health Research Division, National Institute of Environmental Research, Incheon 22733, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youngtae","family":"Choe","sequence":"additional","affiliation":[{"name":"Department of Occupational Health, Daegu Catholic University, Gyeongsan 42472, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5753-0019","authenticated-orcid":false,"given":"Jihun","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Occupational Health, Daegu Catholic University, Gyeongsan 42472, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eunche","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Occupational Health, Daegu Catholic University, Gyeongsan 42472, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gihong","family":"Min","sequence":"additional","affiliation":[{"name":"Department of Occupational Health, Daegu Catholic University, Gyeongsan 42472, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongjun","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Occupational Health, Daegu Catholic University, Gyeongsan 42472, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mansu","family":"Cho","sequence":"additional","affiliation":[{"name":"Department of Occupational Health, Daegu Catholic University, Gyeongsan 42472, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chaekwan","family":"Lee","sequence":"additional","affiliation":[{"name":"Institute of Environmental and Occupational Medicine, Medical School, Inje University, Busan 47392, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kilyong","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Environmental Energy Engineering, Anyang University, Anyang 14028, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Byung Lyul","family":"Woo","sequence":"additional","affiliation":[{"name":"Industrial Hygiene, Preventive Medicine, Force Health Protection, U.
