An investigation by NDR, WDR and SZ has shown that the problem with the poison of the century PFAS is much greater in Germany than previously assumed. The industrially produced chemicals have been detected at over 1,500 locations in Germany. PFAS is a group of more than 10,000 man-made substances that cannot be seen, smelled or tasted. There is a suspicion that they can cause cancer, weaken the immune system and make you infertile. Once in the environment, it is virtually impossible to remove as it does not degrade. These so-called per- and polyfluorinated chemicals are a serious health and environmental problem in Germany.
