Danger from PFT in the environment
PFT are used in many products and industrial areas, such as lubricants, paints, textiles or coatings, due to their simultaneously grease-repellent and water-repellent properties. They can already be released into the environment during their manufacture or during the production of products containing PFT. As PFT do not occur naturally in nature, they are difficult to degrade and are suspected of causing cancer.
PFT remain in the environment for a very long time and are spread via rivers and seas. A high concentration in water poses a danger for the drinking water supply. In order to guarantee a harmless drinking water quality a regular control is inevitable.
