Who / What
Per- and polyfluoroalkyl substances (PFAS), often shortened to PFAS, are a class of synthetic chemical compounds. These chemicals are characterized by having multiple fluorine atoms attached to an alkyl chain. There are approximately 7 million such chemicals listed in PubChem.
Background & History
The widespread use of PFAS began in 1938 with the invention of Teflon, a fluoropolymer coating known for its resistance to heat, oil, stains, grease, and water. PFAS were subsequently incorporated into a vast array of products due to their unique properties. Their development marked a significant advancement in materials science, leading to increased durability and functionality in various applications.
Why Notable
PFAS are notable due to their widespread use in numerous consumer products and their persistence in the environment. These chemicals have a significant impact on human health and ecosystems because they do not readily break down. Concerns regarding PFAS contamination have led to increased research, regulation, and public awareness surrounding these substances.
In the News
PFAS remain a prominent environmental and health concern due to their prevalence in water sources and potential health risks. Recent developments include ongoing efforts by regulatory agencies to establish safe drinking water standards for PFAS and widespread testing for contamination. The issue continues to attract attention from scientists, policymakers, and the public alike.
