Popis: To elucidate the circumstances of their occupational exposure to methyl bromide (MeBr), we conducted a 17-yr study on 124 workers employed by a MeBr manufacturer. Subjects were classified into three groups according to the nature of their work: synthesis group, filling group, and other group. Urinary concentrations of bromide ion (Br(-)) were assessed, and data attained via MeBr-health examinations were analyzed. The highest Br(-) concentrations were seen in the synthesis group, with a median value of 13.0 μg/mg CRE (2.5-51.8), followed by the filling group, with a concentration of 11.9 μg/mg CRE (3.1-34.8). Both values were significantly higher than the levels noted in the other group (p
