Presumptive Contamination: A New Approach to PFAS Contamination Based on Likely Sources
Science
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
Science
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.

An unexpected synergistic toxicity caused by competitive bioconcentration of perfluoroalkyl acid mixtures to Daphnia magna: Further promoted by elevated temperature
Science
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)
Science
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.

Study links in utero ‘forever chemical’ exposure to low sperm count and mobility
News
5 Oct 2022 | The Guardian
A new peer-reviewed Danish study finds that a mother’s exposure to toxic PFAS ‘forever chemicals’ during early pregnancy can lead to lower sperm count and quality later in her child’s life.

[Letter to the editor] The conundrum of the PFOA human half-life, an international collaboration
Science
1 Oct 2022 | RTP
Campbell et al. (2022) propose that many studies estimating the human half-life of PFOA are significantly confounded by lack of accounting for ongoing exposures, which would inflate estimates, and by the presence of branched isomers, which could deflate estimates for linear PFOA.
