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 […]

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 […]

Two Studies Confirm that HFO-1234ze(E) Breaks Down into Some HFC-23 in the Atmosphere
Two recent studies have confirmed that HFO-1234ze(E), a commonly used ultra-low-GWP replacement for HFCs, breaks down in the atmosphere to produce a small amount of HFC-23, which has one of the greatest global warming impacts. The two studies are “Fluoroform (CHF3) Production from CF3CHO Photolysis and Implications for the Decomposition of Hydrofluoroolefins and Hydrochlorofluoroolefins in […]
