Democrats Propose PFAS Legislation in U.S. Congress That Would Include F-Gases and TFA
Two Democrats have proposed legislation in the U.S. House of Representatives and the Senate to address the use of per- and polyfluoroalkyl substances (PFAS) in the domestic supply chain, using a definition of PFAS that would include many refrigerants and the atmospheric byproduct of some refrigerants called trifluoroacetic acid (TFA). The bill, the Forever Chemical Regulation and […]

Monitoring of PFAS, Including TFA, Begins Under EU Drinking Water Directive
As of January 12, member states must measure either total PFAS, including TFA, or the sum of 20 PFAS, with limits of 0.5mcg/L and 0.1mcg/L, respectively. The European Commission announced on January 12 that, under new rules in the EU’s recast Drinking Water Directive, member states must begin monitoring “in a harmonized way” per and polyfluoroalkyl substances (PFAS) levels […]

Pesticides NGO Disputes Chemical Companies’ Interpretation of TFA Toxicity Studies
The Pesticide Action Network (PAN) Europe, a Brussels-based NGO, has released a report that challenges industry interpretations of animal studies looking at the toxicity of trifluoroacetic acid (TFA), a byproduct of some f-gases, pesticides and other chemicals. The report, “Manufacturing Doubt: How the Industry Downplays TFA’s Toxicity,” is based on PAN Europe’s analysis of chemical manufacturer-supported studies “to […]

New research titled “MESSAGE FROM THE BOTTLE: The Rapid Rise of TFA Contamination Across the EU
The new research titled “MESSAGE FROM THE BOTTLE: The Rapid Rise of TFA Contamination Across the EU,” published by members of the European Pesticide Action Network Europe (PAN Europe), reveals a startling and rapidly increasing presence of trifluoroacetic acid (TFA) in European wines. This study underscores the pervasive nature of PFAS contamination and highlights the […]
Read More Study Puts Annual Cost of Removing PFAS from the Environment in Europe, Including TFA, at €100 Billion
The cost of removing PFAS (per- and polyfluoroalkyl substances) from the environment in Europe, including “emerging” PFAS like f-gas by-product trifluoroacetic acid (TFA), would be €100 billion ($108 billion) per year, or €2 trillion ($2.2 trillion) after 20 years, according to the “Forever Pollution” study published by a group of journalists and scientists. PFAS, a class of more […]

How Harmful Is TFA?
A large and growing number of studies have reported the rapid proliferation in the environment of trifluoroacetic acid (TFA), a by-product of certain f-gases in the atmosphere (notably HFO-1234yf) as well as the breakdown of certain pharmaceuticals, pesticides and other chemicals. This begs the question: how harmful is TFA to human beings? TFA is an ultrashort-chain […]
