The Ins and Outs of Per-and Polyfluoroalkyl Substances in the Great Lakes: The Role of Atmospheric Deposition
Science
16 May 2024 | Environmental Science and Technology
Air, water, and precipitation samples from the Great Lakes region revealed varying levels of PFAS, with atmospheric deposition as a significant PFAS source to the lakes. Mass transfer analysis suggests net accumulation of PFAS in northern lakes and elimination in southern ones.

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.
