Prague, Czech Republic The large group of perfluorinated chemicals, collectively known as PFAS and often called "Forever Chemicals" because they are not easily broken down, have been found nearly everywhere researchers have looked for them — but particularly in food, water supplies, and soils. Czech Republic NGO Arnika recently studied sources in and around Prague, and found PFAS, its related chemicals, and additionally brominated flame retardants (BFRs) in nearly every sample. The study, Forever Chemicals Round and Round, made clear that identifying and continually monitoring PFAS and BFR sources is vital for community health and environmental sustainability.
Although regulation of these chemicals is increasing, the categories of perfluorinated and brominated chemicals are large. So as one chemical is identified and listed for restriction, another is adopted for use, all without understanding the underlying health effects. Ironically, many of these substances have known, safe alternatives. In response to studies showing PFAS in blood samples of firefighters, airports have been moving to safer fire-fighting foams, replacing fluorinated forms, which constitute roughly one-third of known PFAS contamination and which have been found in water ways near airports, including in Arnika's recent study.
“Perfluorinated substances and brominated flame retardants are not essential for the majority of applications and there are already safer alternatives on the market today. Therefore, their production should stop immediately. We call on both manufacturers and legislators to restrict the use of these toxic substances for all non-essential purposes. The deterioration in the quality of drinking water and the global environmental contamination caused by PFAS are irreversible,” says Jitka Strakova from Arnika.
