Macro and trace-elemnts in drinking water and diet. Paper 2: calcium, magnesium, cobalt chromium, manganese, nickel, copper, zinc, cadium, lead in drinking water in the Marche Region.

The results of systemic dose-sampling of some mcro and trace-elemnts in drinking water in the Marche Region are described. The concentrations of such elements in drinking waters of all the considered Communes result below the limit values indicated by OMS. In Pesaro and Ancona provinces the higest concentrations and remarkable variation in the distribution have bee found so that a role exerted by greater industrila development in the above mentioned provinces is supposed. Furthermore, the significance of the role of foods to feed the organism with such elements is stressed. Though the quantities igested with drinking water represent a rather low percentage as compared with quantities ingested with food-stuffs, the absorption by drinking water is much higher than absorption from foods. The importance of the exact knowledge of the mineral is also stressed contribution not only as quantitative relations among the elements that can determine mineral imbalances to organism, at present sudied by researches to get possible correlations with chronic diseases
