This study evaluated occupational exposure to hazardous chemicals among transport workers during actual tanker loading and unloading operations using both conventional personal sampling and real-time volatile organic compound (VOC) monitoring.<\/jats:p>\n                  <jats:p>Field exposure assessments were conducted during 9 loading and unloading operations at 2 workplaces. Loading and unloading activities were classified into 3 work stages: hose connection, chemical transfer, and hose disconnection. Personal exposure was assessed using both active and passive sampling methods, while transient VOC concentrations were evaluated using real-time monitoring.<\/jats:p>\n                  <jats:p>Personal exposure levels measured by conventional sampling were generally low or non-detectable and remained below applicable occupational exposure limits. In contrast, real-time monitoring revealed repeated transient increases in VOC concentrations during hose disconnection, with peak concentrations exceeding 2,500 ppb during phenol loading, approximately 1,200 ppb during xylene loading, and approximately 16,000 ppb during toluene loading. Although these transient peaks did not exceed the applicable short-term exposure limits, they demonstrated short-duration exposure events that were not adequately reflected by TWA measurements.<\/jats:p>\n                  <jats:p>These findings indicate that hose disconnection represents a critical exposure task during tanker loading and unloading operations and highlight the value of task-based exposure assessment for identifying transient exposure events. Engineering controls to reduce residual chemical release, together with appropriate personal protective equipment management, should be considered to improve occupational exposure management for hazardous chemical transport workers.<\/jats:p>","DOI":"10.1093\/annweh\/wxag078","type":"journal-article","created":{"date-parts":[[2026,9,4]],"date-time":"2026-09-04T11:35:45Z","timestamp":1788521745000},"source":"Crossref","is-referenced-by-count":0,"title":["Task-based transient volatile organic compounds exposure during tanker loading and unloading among hazardous chemical transport workers in South Korea"],"prefix":"10.1093","volume":"70","author":[{"given":"Doo-Young","family":"Kim","sequence":"first","affiliation":[{"name":"Safety Policy Research Division, National Fire Research Institute , 88, Yeonsudanji-gil, Sagok-myeon, Gongju-si, Chungcheongnam-do 32522, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dae-Sung","family":"Lim","sequence":"additional","affiliation":[{"name":"Department of Occupational Safety and Health, Wonkwang Digital University , 460, Iksan-daero, Iksan-si, Jeollabuk-do 54538, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,9,15]]},"reference":[{"key":"2026091506051139400_wxag078-B1","doi-asserted-by":"publisher","DOI":"10.1016\/j.atmosenv.2020.117847","article-title":"Health symptoms associated with occupational exposure of gasoline station workers to BTEX compounds","volume":"241","author":"Al-Harbi","year":"2020","journal-title":"Atmos Environ"},{"key":"2026091506051139400_wxag078-B2","doi-asserted-by":"publisher","first-page":"57","DOI":"10.1080\/00028899908984423","article-title":"Studying the determinants of exposure: a review of methods","volume":"60","author":"Burstyn","year":"1999","journal-title":"Am Ind Hyg Assoc J"},{"key":"2026091506051139400_wxag078-B3","doi-asserted-by":"publisher","DOI":"10.1016\/j.etap.2020.103518","article-title":"Effects of inhaled combined benzene, toluene, ethylbenzene, and xylenes (BTEX): toward an environmental exposure model","volume":"81","author":"Davidson","year":"2021","journal-title":"Environ Toxicol Pharmacol"},{"key":"2026091506051139400_wxag078-B4","doi-asserted-by":"publisher","first-page":"423","DOI":"10.1539\/joh.11-0111-OA","article-title":"Exposure assessment of ETBE in gas station workers and gasoline tanker truck drivers","volume":"53","author":"Eitaki","year":"2011","journal-title":"J Occup Health"},{"key":"2026091506051139400_wxag078-B5","doi-asserted-by":"publisher","first-page":"890","DOI":"10.1093\/annweh\/wxz055","article-title":"Benzene exposure and biomarkers in alveolar air and urine among deck crews on tankers transporting gasoline","volume":"63","author":"Forsell","year":"2019","journal-title":"Ann Work Expo Health"},{"key":"2026091506051139400_wxag078-B6","doi-asserted-by":"publisher","first-page":"111","DOI":"10.3390\/toxics11020111","article-title":"Exposure to volatile organic compounds in paint production plants: levels and potential human health risks","volume":"11","author":"Ghobakhloo","year":"2023","journal-title":"Toxics"},{"key":"2026091506051139400_wxag078-B7","doi-asserted-by":"publisher","first-page":"19","DOI":"10.1016\/j.ecoenv.2017.10.070","article-title":"Biomonitoring-based exposure assessment of benzene, toluene, ethylbenzene and xylene among workers at petroleum distribution facilities","volume":"149","author":"Heibati","year":"2018","journal-title":"Ecotoxicol Environ Saf"},{"key":"2026091506051139400_wxag078-B8","volume-title":"Exposure to hazardous chemicals at work and resulting health impacts: a global review","author":"International Labour Office","year":"2021"},{"key":"2026091506051139400_wxag078-B9","doi-asserted-by":"publisher","first-page":"253","DOI":"10.1093\/annhyg\/37.3.253","article-title":"A comprehensive evaluation of within- and between-worker components of occupational exposure to chemical agents","volume":"37","author":"Kromhout","year":"1993","journal-title":"Ann Occup Hyg"},{"key":"2026091506051139400_wxag078-B10","doi-asserted-by":"publisher","DOI":"10.1080\/23311843.2019.1603418","article-title":"Occupational exposure of benzene, toluene, ethylbenzene and xylene (BTEX) to pump attendants in Ghana: implications for policy guidance","volume":"5","author":"Kuranchie","year":"2019","journal-title":"Cogent Environ Sci"},{"key":"2026091506051139400_wxag078-B11","doi-asserted-by":"publisher","first-page":"540","DOI":"10.1539\/joh.47.540","article-title":"Occupational exposure to volatile organic compounds and mitigation by push-pull local exhaust ventilation in printing plants","volume":"47","author":"Leung","year":"2005","journal-title":"J Occup Health"},{"key":"2026091506051139400_wxag078-B12","volume-title":"NIOSH Manual of analytical methods. 4th ed.
