[A population study on the possible involvement of trace minerals in water in cardiovascular diseases].

Starting from the hypothesis of a possible protection exerted by oligominerals in cardiovascular diseases, 660 water sources were analysed as to their content in mineral matter. It resulted that the population drinks a very hard water with a low content in zinc, manganese, copper and chromium oligominerals. By correlating these characteristics with the mortality rate by cardiovascular diseases, low in the territory under study, it became evident that no association between these factors can be made, the relative protection being probably due to other factors.
