Scientists from the German Environmental Protection Agency found 20 compounds of the “forever chemical” PFAS in drinking water across the country. In some cases their concentrations exceeded the safe threshold. The study was published in the scientific journal magazine Eco-Environment and Health (EEH).
PFAS (per- and polyfluoroalkyl compounds) are substances commonly used in many industries, including clothing, carpets, food packaging and kitchenware. They are known for their resistance to degradation, which is why they are called “forever chemicals.”
“Eternal chemicals” enter the body not only through drinking water, but also through products packaged with ingredients containing these substances. PFAS may increase the risk of cancer, birth defects in babies, liver and thyroid diseases, decreased immune system, and hormonal disorders.
The study involved collecting 89 drinking water samples from different parts of Germany and analyzing them for the presence of 26 different PFAS using tandem mass spectrometry and high-performance liquid chromatography.
The results showed that although 20 regulated PFAS were below the detection limit, total concentrations varied widely, with some samples exceeding the safe threshold for hazardous substances.
The report’s authors hope their work will help inform future regulatory decisions and recommendations regarding drinking water quality.
Previous scientists discovered Hundreds of tonnes of PFAS circulating in Arctic waters.
