Associations between PFAS concentrations and the oxidative status in a free-living songbird (Parus major) near a fluorochemical facility
Science
25 Sep 2023 | Environ Pollut
Some songbirds with high PFAS concentrations exhibit increased antioxidant defenses, indicating that they have managed to protect themselves against potential PFAS-induced oxidative stress, which may impact their overall well being.

An integrated assessment of ecological and human health risks of per- and polyfluoroalkyl substances through toxicity prediction approaches
Science
18 Sep 2023 | Sci Total Environ
PFOS and PFOA are the most prevalent PFAS in surface water and in humans, and modeling indicates that they result in endocrine disruption and multi-generational behavioral effects.

Evaluation of sealants to mitigate the release of per-and polyfluoroalkyl substances (PFAS) from AFFF-impacted concrete: characterization and forecasting
Science
14 Aug 2023 | Water Research X
Simulated rainfall scenarios indicate that sealing concrete surfaces previously contaminated with AFFF reduces the leaching of PFAS, while unsealed concrete surfaces could continue to release PFOS for a period of 15 years or more.

Prenatal and childhood exposure to per-/polyfluoroalkyl substances (PFASs) and its associations with childhood overweight and/or obesity: a systematic review with meta-analyses
Science
14 Aug 2023 | Environ Health
The review revealed positive correlations between prenatal PFNA and BMI, between PFOA and BMI in children older than 3 years, as well as between prenatal PFNA and waist circumference. Negative associations were found between prenatal PFOS and BMI in children younger than 3 years and PFHxS and the risk of being overweight.
