THE PFAS were then used starting in the '50s as emulsifiers and surfactants in cleaning products, in the formulation of insecticides, protective coatings, fire-fighting foams and paints. They are also used in the production of clothing, waterproof products for printers, photographic film and the wall surfaces, in materials for microelectronics. The compounds perfluoroalchilici are used also in the linings of the containers for the food, such as those of the "fast food" or in cardboard boxes of pizzas for take away, in the production of PTFE (notes from non-stick properties), and new materials that have found application in numerous fields such as quellotessile. As a result of the extensive production and use of PFAS, and their peculiar physical and chemical characteristics, these compounds were frequently detected in significant concentrations in samples of environmental organisms, including human beings.
