ROMA – The chemical industry had presented it as the clean model of the Pfas, referring to the chemical compound that had made the waters of four provinces of Veneto dangerous, leaking from the Miteni factory into a stream in the industrial area of Vicenza. The C604, in the intentions of the producers of resins for skis, non-stick for pans, waterproofing for jackets, should have put behind them the season of perfluoroalkyls and their residues that guarantee citizens of all ages kidney dysfunction, cholesterol out of control. , the certified risk of heart attacks.
Research from the University of Padua, Departments of Comparative Biomedicine and Food and Biology, has shown that substance C604, the substitute, a acetic and acid perfluoro, however, it alters the biological processes of sentinel marine organisms, such as the clam clam, which enter the human food cycle.
The research, carried out in collaboration with the Water Research Institute of the National Research Council (Isra-Cnr di Brugherio), was published in “Environmental International“, a prestigious scientific journal of environmental studies. The work started with the indication of the Veneto Regional Environmental Protection Agency, which detected high levels of C6O4 in groundwater and in the Po River. On the new compound used by the chemical industry (to replace the Pfoa, belonging to the Pfas family) there was no scientific documentation or environmental literature.

The two departments of the University of Padua have chosen to analyze the Filipino clam, otherwise called true, grown in the lagoon, appreciated on the table and sentinel organism, as a sponge of the sea, of the ecosystem. The researchers found alterations, after exposure of the clam to C6O4, to fundamental biological processes such as the immune response, the development of the nervous system and lipid metabolism. “These are all very alarming figures,” explained the professor Tomaso Patarnello, from the Department of Comparative Biology and Nutrition, “the results of our research clearly demonstrate that C6O4 significantly alters, and in some ways even more than Pfoa, the biological processes of the Philippine clam”.
Professor Massimo Milan, who followed the experimental part of the project together with Professor Valerio Matozzo, he adds: “The fact that this substance is used without any legal limit, assuming that it has no effect on exposed organisms, is clearly contradicted by our experimental data”.
The next studies will have to try to understand what are the effects of the chemical compound on man and his environmental health.
