The authors suggest improvements for PFAS analysis in foods, such as using emerging extraction methods as a fast and less labor-intensive approach, and make further suggestions regarding PFAS detection.
Impact of PFAS exposure on prevalence of immune-mediated diseases in adults in the Czech Republic
26 Apr 2023 | Environ Res.
PFAS exposure was found to have some adverse immune effects, including an association of elevated PFOS levels in men with higher rates of eczema.
Smouldering to treat PFAS in sewage sludge
25 Apr 2023 | Waste Manage.
Smoldering combustion completely removed all 4-8 carbon chain length PFAS from sewage sludge under all conditions, though extremely high temperatures and the addition of CaO were needed to mineralize the PFAS completely.
Early life exposure to low-dose perfluorooctane sulfonate disturbs gut barrier homeostasis and increases the risk of intestinal inflammation in offspring
24 Apr 2023 | Environ Pollut
Low-dose PFOS exposure disrupted the developing digestive functions in a human model species.

Mechanistic Middle-Out Physiologically Based Toxicokinetic Modeling of Transporter-Dependent Disposition of Perfluorooctanoic Acid in Humans
18 Apr 2023 | ES&T
A new model was developed to explain the persistence of PFOA in humans after both high-dose, acute and low-dose, chronic exposures.
Global ocean contamination of per- and polyfluoroalkyl substances: A review of seabird exposure
18 Apr 2023 | Chemosphere
Seabirds had higher levels of PFOS exposure – often exceeding toxicity reference values in places like the Baltic Sea and the San Francisco Bay – in the late 1990s and early 2000s, consistent with the phase-out of PFOS-based chemicals.
70 analyte PFAS test method highlights need for expanded testing of PFAS in drinking water
17 Apr 2023 | Sci. Total Environ.
Unregulated Contaminant Monitoring Rule will likely underreport PFAS in drinking water due to existing methods’ limited coverage and higher minimum reporting limits. The most common PFAS present was PFPrA, a poorly studied and monitored short-chain PFAS.
Pharmaceuticals Account for a Significant Proportion of the Extractable Organic Fluorine in Municipal Wastewater Treatment Plant Sludge
17 Apr 2023 | Environ. Sci. Technol. Lett.
Pharmaceutical substances and pesticides can contribute to sizable portions of the organofluorine content detected in wastewater treatment plant sludge.
Ecological characteristics impact PFAS concentrations in a US North Atlantic food web
17 Apr 2023 | Sci Total Environ
PFAS concentrations were related to species, body size, habitat, feeding guild, and location, with PFDA, PFOS, and FOSA levels being the highest in game species that live within the water column.
Weight loss relapse associated with exposure to perfluoroalkylate substances
17 Apr 2023 | Obesity
PFOA and PFHxS plasma concentrations were associated with increased weight gain, meaning obesogenic PFAS may cause weight gain and thus contribute to the obesity pandemic.
