A new peer-reviewed study published in Atmospheric Chemistry and Physics simulated rainwater concentrations of trifluoroacetic acid (TFA) from the degradation of projected HFO-1234yf usage in India, China, and the Middle East through 2040. Here are the points you need to know:
- The study affirms that TFA from HFO-1234yf refrigerants has a negligible effect on human and ecosystem health. This is consistent with findings of previous studies focused on the U.S., Europe, and China.
- Even in scenarios envisioning the largest emissions of HFO-1234yf through 2040, TFA rainwater concentrations remain orders of magnitude below the no observable effect concentrations (NOECs) in ecological and mammalian toxicology studies.
- The study completes our knowledge on the human and ecological impact of TFA from HFO-1234yf for the most populated and high economic growth regions in the world.
What this means for the HVACR industry: The study is consequential because it is an important addition to the growing body of atmospheric research that strongly indicates that the risks of TFA from HFO-1234yf are insignificant. Advanced Climate Technologies—including low-GWP HFCs, HFOs, and blends—are safe and reliable solutions for the long term.
