摘要:Introduction. The limited scientific knowledge on the relationship between exposureand health effects in relation to geothermal activity motivated an epidemiologic investigationof Tuscan geothermal area.Aim. This study aims at describing mortality of populations living in Tuscan municipalitiesin the period 2003-2012.Method. Sixteen municipalities were included in the study area: eight in the northernand eight in the southern area. Mortality data come from the Regional Mortality Registryof Tuscany. Fifty-four causes of death, considered of interest for population healthstatus or consistent with “Project SENTIERI” criteria, are analyzed.Results. Results show a worse mortality profile in the southern area, especially in males,for whom excesses of all cancers and some causes of cancer emerge, while in the northernarea an excess of cerebrovascular diseases among females merits attention. Furtherand more appropriate studies are needed to clarify the etiology of some diseases and tobetter assess a potential cause-effect relationship.
