PFAS are a large, complex category of manufactured chemicals that are found in many commonplace products.The term “forever chemicals” refers to a group of manufactured chemicals that have been used extensively since the 1940s. They cannot be destroyed by fire, eaten by bacteria, or diluted by water. Furthermore, if these harmful chemicals are buried, they seep into the earth surrounding them and persist for future generations.have now accomplished what seemed impossible.
But over time, PFAS has found its way out of consumer goods and into our water supply and even into the blood of 97% of Americans. Exposure to PFAS is strongly linked to decreased fertility, impacts on children’s development, higher risks for many forms of cancer, reduced immunity to infections, and elevated cholesterol levels, although the health implications are not yet completely understood. The U.S.
The secret to PFAS’s indestructibility lies in its chemical bonds. PFAS contains many carbon-fluorine bonds, which are the strongest bonds in organic chemistry. As the most electronegative element in the periodic table, fluorine wants electrons — and badly. Carbon, on the other hand, is more willing to give up its electrons.
In previous attempts to destroy PFAS, other researchers have used high temperatures — up to 400 degrees. Dichtel is excited that the new technique relies on milder conditions and a simple, inexpensive reagent, making the solution potentially more practical for widespread use.
