Partitioning of PFAS to serum, tissues, eggs, and hatchlings of an Australian freshwater turtle
Science
15 Apr 2024 | J. Hazard. Mater.
Higher levels of certain PFAS were discovered in male turtles compared to females, with PFOS being the most prevalent in the turtles' tissues, while PFHxA was predominant in the surrounding water. All of the long chain PFAS were transferred from yolk to hatchling, suggesting an intergenerational effect.

“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).

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.
