“When we look for PFAS, typically guess what? We find it. And that’s the nature of the chemical: it does not break down in the environment, it does accumulate in our bodies, so the less we ingest the better off we are,” says James Kenney, cabinet secretary of the New Mexico Environment Department (NMED).

Constraining global transport of perfluoroalkyl acids on sea spray aerosol using field measurements
Science
5 Apr 2024 | Science Advances
PFAAs were found to be present in sea spray aerosols in global oceans at levels significantly higher than in seawater, indicating that sea spray aerosols emissions may be a major source of PFAAs in the atmosphere, comparable to or greater than other known sources such as manufacturing emissions and precursor degradation.

On the Chemical Pathways Influencing the Effective Global Warming Potential of Commercial Hydrofluoroolefin Gases
Science
4 Apr 2024 | ChemSusChem
The introduction of hydrofluoroolefins as a low Global Warming Potential substitute for hydrofluorocarbons raised concerns about the long-term atmospheric fate of their primary degradation products, particularly TFE, TFF, and TF due to the potential secondary formation of HFC-23, a potent greenhouse pollutant. This analysis indicates a need for further research to assess the climate risks associated with HFOs.
