The concentration of "eternal chemicals" in rainwater is exceeded almost all over the world.

Swedish and Swiss scientists have measured the concentrations of four major "timeless chemicals" in rainwater and found that they are well above safe levels almost everywhere in the world. In particular, the norms established in the USA for drinking water. "Eternal Chemicals" (PFAS) is a group of 4.7 thousand artificially synthesized substances. The most famous of them is Teflon. They are used to dye clothing and food packaging; creation of cosmetics; production of dirt- and water-repellent coatings. Ingested PFAS increases the risk of cancer, malformations in newborns, liver and thyroid diseases, and hormone problems.
