RT Journal Article SR Electronic T1 The impact of residential proximity to ophiolitic units in the development of asbestos related diseases JF European Respiratory Journal JO Eur Respir J FD European Respiratory Society SP p1052 VO 38 IS Suppl 55 A1 Mehmet Bayram A1 Isa Döngel A1 Nur Dilek Bakan A1 Huseyin Yalcin YR 2011 UL http://erj.ersjournals.com/content/38/Suppl_55/p1052.abstract AB Aim: To determine the relation between risk of asbest related diseases (ARD) and the proximity of birthplaces to ophiolitic units (OU) which contains serpentin in province of Sivas, Turkey.Method: Records between 2000 and 2010 of mesothelioma, pleural plaque (PP), prostate cancer and breast cancer patients from cancer registry were reviewed. Samples were obtained from indoor plasters and source of plasters. Birthplaces of patients were marked on a map with OU modified from geological map (mesothelioma: red square, PP: black star and OU: green areas).The distance between residental area of birthplace of the patients and OU were measured.Result: Birthplaces of 100 mesothelioma, 133 PP, 161 prostate cancer and 139 breast cancer patients were included. Samples of plasters and soil were identified as 95% serpentine. Mean distance to OU of patients with ARD and control cases were 5.9 and 15.5 kilometers.Logistic regression analysis after age adjustment between groups showed that risk for ARD increased with decrease of distance to OU (Odds ratio: 1.72 for every 5 km decrease).Conclusion: The proximity of birthplace to OU increases the risk of ARD.
