A review of the cohorts with environmental and occupational mineral fiber exposure

Abstract

ABSTRACTThe aim of the study was to examine factors associated with Malignant Mesothelioma (MM) incidence rate of the groups with occupational asbestos and environmental asbestos or erionite exposure in rural area. In this ecological study, a total of 21 cohort datasets (8 environmental and 13 occupational) were evaluated. Data were analyzed using a multiple linear regression analysis model. In environmental cohorts, the risk of MM incidence was higher in women and people exposed to erionite. In this cohort, the incidence rate of MM increased as the median exposure time increased, while the incidence decreased as the median cumulative exposure dose increased. In occupational cohorts, the incidence rate of MM was positively correlated with the median cumulative exposure dose. The risk of mesothelioma was lower in those exposed to tremolite than others. Environmental asbestos exposure is as important as occupational exposure to develop MM, and it has its own unique exposure features on the risk of MM.
