This study investigated the effect of occupational ELF\u2010MF exposure on 6\u2010sulfatoximelatonin (6\u2010OHMS). Exposure was monitored for three complete work shifts in 59 workers using personal exposure meters. Environmental exposure was also evaluated. Urinary 6\u2010OHMS in morning samples, an indicator of night\u2010time melatonin production, was measured. Urine was collected twice on Friday and the following Monday. Workers were classified according to ELF exposure as low exposed (\u22640.2 \u00b5T) or higher exposed (&gt;0.2 \u00b5T): 6\u2010OHMS did not differ between groups (<jats:italic>P<\/jats:italic>\u2009&gt;\u2009.05) in either Friday or Monday urine samples. In addition, 6\u2010OHMS was not related to exposure under multivariate analysis. The ratio between 6\u2010OHMS in Monday versus Friday samples was also calculated to test the hypothesis of a possible variation in pineal function after 2 days, interruption of occupational ELF\u2010MF exposure: again no exposure\u2010related difference was observed. Our results do not support the hypothesis that occupational exposure to ELF\u2010MF significantly influences melatonin secretion.
