As part of the creation of the Baie Verte Miners\u2019 Registry in 2008, a two-dimensional job exposure matrix (JEM) was developed for estimating asbestos exposures for former chrysotile asbestos miners\/millers. Industrial hygiene data collected between 1963 and 1994 were analysed to assess validity for use in a retrospective exposure assessment and epidemiologic study. Registered former employees were divided into 52 exposure groups (EGs) based on job title and department and mean asbestos concentrations were calculated for each EG. The resulting exposure estimates were linked to individual registrants\u2019 work histories allowing for the calculation of cumulative asbestos exposure for each registrant. The distribution of exposure for most EGs (82.6%) could be described as fitting a log-normal distribution, although variability within some EGs (55%) exceeded a geometric standard deviation (GSD) of 2.5. Overall, the data used to create EGs in the development of the JEM were deemed to be of adequate quality for estimating cumulative asbestos exposures for the former employees of the Baie Verte asbestos mine\/mill. The variability between workers in the same job was often high and is an important factor to be considered when using estimates of cumulative asbestos exposure to adjudicate compensation claims. The exposures experienced in this cohort were comparable to those of other chrysotile asbestos miners\/millers cohorts, specifically Italian and Qu\u00e9bec cohorts.<\/jats:p>","DOI":"10.1093\/annweh\/wxaa092","type":"journal-article","created":{"date-parts":[[2020,8,24]],"date-time":"2020-08-24T19:27:44Z","timestamp":1598297264000},"page":"113-126","source":"Crossref","is-referenced-by-count":4,"title":["A Quantitative Retrospective Exposure Assessment for Former Chrysotile Asbestos Miners and Millers from Baie Verte, NL, Canada"],"prefix":"10.1093","volume":"65","author":[{"given":"Tina","family":"Giles Murphy","sequence":"first","affiliation":[{"name":"Memorial University of Newfoundland, SafetyNet Centre for Occupational Health & Safety Research, Bruneau Centre, St. John\u2019s, NL, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen","family":"Bornstein","sequence":"additional","affiliation":[{"name":"Memorial University of Newfoundland, SafetyNet Centre for Occupational Health & Safety Research, Bruneau Centre, St. John\u2019s, NL, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Oudyk","sequence":"additional","affiliation":[{"name":"Occupational Health Clinics for Ontario Workers, Hamilton, ON, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul A","family":"Demers","sequence":"additional","affiliation":[{"name":"Occupational Cancer Research Centre, Cancer Care Ontario, Toronto, ON, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2020,9,22]]},"reference":[{"year":"2005","author":"AMEC Earth & Environmental","key":"2021011405443559500_CIT0001"},{"year":"2010","author":"American Industrial Hygiene Association","key":"2021011405443559500_CIT0002"},{"key":"2021011405443559500_CIT0003","doi-asserted-by":"crossref","first-page":"49","DOI":"10.1080\/10408440802273156","article-title":"A meta-analysis of asbestos-related cancer risk that addresses fiber size and mineral type","volume":"38","author":"Berman","year":"2008","journal-title":"Crit Rev Toxicol"},{"key":"2021011405443559500_CIT0004","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1080\/10408440802276167","article-title":"Update of potency factors for asbestos-related lung cancer and mesothelioma","volume":"38","author":"Berman","year":"2008","journal-title":"Crit Rev Toxicol"},{"year":"2013","author":"Bornstein","key":"2021011405443559500_CIT0005"},{"key":"2021011405443559500_CIT0006","doi-asserted-by":"crossref","DOI":"10.3320\/978-1-931504-69-0","volume-title":"A strategy for assessing and managing occupational exposures","author":"Bullock","year":"2006","edition":"3"},{"key":"2021011405443559500_CIT0007","doi-asserted-by":"crossref","DOI":"10.1093\/acprof:oso\/9780195092424.001.0001","volume-title":"Research methods in occupational epidemiology","author":"Checkoway","year":"2004","edition":"2"},{"key":"2021011405443559500_CIT0008","doi-asserted-by":"crossref","first-page":"135","DOI":"10.1007\/s11596-012-0024-8","article-title":"Analysis of mortality in chrysotile asbestos miners in China","volume":"32","author":"Du","year":"2012","journal-title":"J Huazhong Univ Sci Technol Med Sci"},{"volume-title":"Dust exposure and health status present and projected of Baie Verte chrysotile asbestos miners and millers.
