Abstract: Cork closures for fine wine bottles are made from the production of the most sustainable of all agro-industries, the one known for the continuous conservation of cork oak forests in the western mediterranean basin. The current use of this raw material for closing recipients containing products for human consumption had always posed to all the need to assess its quality. There are a number of studies regarding the Lead content of cork which have never been compared even though from their crossing remarkably information arises. Here are shown facts and trends about how small are cork Lead contents. This shows that the hypothesis of poisoning by Lead (Saturnism) trough cork is unlikely to be verified with such low concentrations as the ones already measured, both by others in the past as by our own team voltammetric study of cork, the first of its kind.
