Environmental exposure and ecological risk of perfluorinated substances (PFASs) in the Shaying River Basin, China
19 Jul 2023 | Chemosphere
PFAS exposure via inhalation of particulate matter was found to be dominated by low levels of PFSAs and PFCAs, but inhalation exposure is still important due to its long-term and cumulative nature.
Extending Nontargeted Discovery of Environmental Chemical Exposures during Pregnancy and Their Association with Pregnancy Complications-A Cross-Sectional Study
19 Jul 2023 | Environ Health Perspect
Underused nontargeted analysis methods were used to detect linear PFOS, PFHxS, octadecanedioic acid, and deoxycholic acid in at least 97% of maternal samples, potentially leading to pregnancy complications.
Effective communications strategies to increase the impact of environmental health research
18 Jul 2023 | Environ Health
Among peer-reviewed papers with a press release, media attention was associated with better abstract and press release readability, and scholarly citations were associated with media attention, the presence of a press release, and open-access status. Recommendations are also provided for authors to increase the reach and impact of future papers.
Linking drivers of plant per-and polyfluoroalkyl substance (PFAS) uptake to agricultural land management decisions
17 Jul 2023 | Biointerphases
A review of the literature suggests that the variation in plant PFAS uptake is influenced by a host of factors including the composition of PFAS chemicals, soil conditions, and plant physiology.

A State-of-the-Science Review of Interactions of Per-and Polyfluoroalkyl Substances (PFAS) with Renal Transporters in Health and Disease: Implications for Population Variability in PFAS Toxicokinetics
13 Jul 2023 | Environ Health Perspect.
This state-of-the-science review integrated current knowledge to assess how changes in kidney function and transporter expression from health to disease could affect PFAS toxicokinetics and identified priority research gaps that should be addressed to advance knowledge.
Per- and polyfluoroalkyl substances (PFAS) measured in seafood from a cross-section of retail stores in the United States
13 Jul 2023 | J Hazard Mater
PFAS levels in several grocery store seafood samples were found to exceed safe levels, and PFBS from food storage bags contaminated the fish, potentially leading to a substantial impact on human exposure.
Assessment of exposure to perfluorinated industrial substances and risk of immune suppression in Greenland and its global context: a mixed-methods study
7 Jul 2023 | Lancet Planet Health
An Inuit cohort of hunting families had the highest non-occupational long-term exposure to PFAS worldwide despite their remote location far from industrial sources, with 86% of participants in the most severe risk category based on their blood serum concentrations.
An LC-MS/MS method for the quantitative determination of 57 per- and polyfluoroalkyl substances at ng/kg levels in different food matrices
6 Jul 2023 | Food Addit Contam Part A Chem Anal Control Expo Risk Assess
An analytical method was optimized for quantifying the amount of PFAS in milk powder, milk-based infant formula, meat-based baby food puree, fish and fish oil, fresh egg, and soluble coffee, with limits of quantification low enough to comply with EU regulation.
The Total Oxidizable Precursor (TOP) Assay as a Forensic Tool for Per-and Polyfluoroalkyl Substances (PFAS) Source Apportionment
5 Jul 2023 | ACS ES&T Water
Researchers created a model for allocating the sources of PFAS contamination using a more comprehensive detection method.
Occurrences and fates of per-and polyfluoralkyl substances in textile dyeing wastewater along full-scale treatment processes
1 Jul 2023 | Water Res
PFAS were found in high concentrations in textile dyeing wastewater treatment plant influent, effluent, and sludge, with additional PFAA increasing by a factor of 2.3-4.1 after oxidation by the TOP assay.
Research Progress on Neurodevelopmental Toxicity in Offspring after Indirect Exposure to PFASs in Early Life
30 Jun 2023 | MDPI
According to available scientific literature, early life exposure to PFAS may result in neurodevelopmental toxicity through oxidative stress and the development of abnormal nerve cells.
Prenatal exposure to per- and polyfluoroalkyl substances and infant sleep disturbance: A prospective cohort study
28 Jun 2023 | Environ Int
Exposure to several PFAS was significantly associated with an increased risk of sleep disturbance in infants, including nighttime awakenings, snoring, and longer nocturnal wakefulness.
Factors affecting serum PFAS concentrations among US females with surgically and naturally induced menopause: data from NHANES 2003-2018
27 Jun 2023 | Environ Sci Pollut Res Int
Supplementary hormone use, and specifically estrogen hormones, are associated with higher serum PFAS in postmenopausal women.
Per-and Polyfluoroalkyl Substances (PFAS) in United States Tapwater: Comparison of Underserved Private-Well and Public-Supply Exposures and Associated Health Implications
26 Jun 2023 | Environ. Int.
Models based on drinking water testing suggest that at least one PFAS is present in 45% of US drinking water. The authors recommend that monitoring should be improved by including more rural and private wells and by expanding target and non-target analysis methods.
