12 Oct 2022 | ES&T
A contamination model was used to create a map of presumptive PFAS contamination sites in the United States, identifying more than 57,000 sites including industrial facilities, wastewater treatment plants, current or former military sites, and airports.
Use and release of per-and polyfluoroalkyl substances (PFASs) in consumer food packaging in US and Canada
11 Oct 2022 | Chemosphere
Most food packaging does not contain intentionally added PFAS, indicating that PFAS are not necessary for food packaging, yet the thousands of tonnes of PFAS still used have the potential to contaminate the environment and waste streams.

PFOS was detected in 6 out of 10 tested insecticides at concentrations up to 19,200,000 ppt, with 7 additional PFAS found via non-targeted techniques.
An unexpected synergistic toxicity caused by competitive bioconcentration of perfluoroalkyl acid mixtures to Daphnia magna: Further promoted by elevated temperature
7 Oct 2022 | Environ Pollut
High temperatures promote the bioconcentration of PFAA and resulted in the increased toxicity of PFAA mixtures in model species.
An Integrated Approach for Determination of Total Per-and Polyfluoroalkyl Substances (PFAS)
5 Oct 2022 | Environ. Sci. Technol.
This paper describes how to use methods like the total oxidizable precursor assay and suspect screening to more fully characterize PFAS present in soil and aqueous mixtures as such screenings can help inform the potential for PFAS exposure.
