In a region in the upper Valais with partly elevated mercury levels in soil, we conducted a mercury biomonitoring study in urine and hair of women and children. Our research questions were, if the mercury in soil poses a health risk for the residential population, if there was an association between mercury-soil- and mercury-biomonitoring-values and to compare the biomonitoring-values with results from other studies. We invited all inhabitants that fulfilled the inclusion criteria. Furthermore, we used questionnaires to identify additional risk factors.
