Let’s talk about PFAS: Inconsistent public awareness about PFAS and its sources in the United States
16 Nov 2023 | PLOS ONE
A nationwide survey revealed that nearly half of respondents were unaware of PFAS, with 97.4% expressing a belief that their drinking water had not been impacted by PFAS, highlighting a crucial need for improved communication and awareness efforts regarding PFAS information and health risks.
Per- and poly-fluoroalkyl substances in commercial organic eggs via fishmeal in feed
7 Nov 2023 | Chemosphere
Organic eggs from certain farms in Denmark were found to contain elevated levels of PFAS originating from fishmeal used in organic feed, leading to the voluntary removal of fishmeal from the feed by producers to mitigate PFAS exposure.
Complex monitoring of perfluoroalkyl substances (PFAS) from tap drinking water in the Czech Republic
6 Nov 2023 | Water Research
PFAS levels in drinking water in the Czech Republic were found to be very low and comparable to other recent European studies, and the authors concluded that only about 1% of the samples could pose a potential health risk.
Prevalence and Source Tracing of PFAS in Shallow Groundwater Used for Drinking Water in Wisconsin, USA
2 Nov 2023 | Environ Sci Technol
Human waste sources, septic systems in particular, are important sources of PFAAs, especially ones with 8 or less perfluorinated carbons, in shallow groundwater.
Spatial Prediction of Concentrations of Per-and Polyfluoroalkyl Substances (PFAS) in European Soils
31 Oct 2023 | Environ. Sci. Technol. Lett.
Machine learning was used to predict PFAS concentrations in European soils, revealing that a substantial portion of European soils may be contaminated with PFAS at levels exceeding recommended guidelines and providing valuable geospatial information for assessing environmental risks.
Exposure to perfluoroalkyl and polyfluoroalkyl substances and pediatric obesity: a systematic review and meta-analysis
31 Oct 2023 | Int J Obes (Lond)
The review investigated the potential impact of PFAS on childhood obesity. It observed a possible inverse relationship between postnatal PFAS exposure and changes in body mass index though the review was limited by the small number of studies.
Trends in Serum Per-and Polyfluoroalkyl Substance (PFAS) Concentrations in Teenagers and Adults, 1999–2018 NHANES
27 Oct 2023 | Int. J. Environ. Res. Public Health
Some longer chain PFAS levels in serum have decreased over time, however they are still detected in drinking water and consumer products, with certain racial/ethnic groups showing differing levels of exposure, highlighting the need for continued monitoring.
Is it raining PFAS in France? An analysis of 52 PFAS at ng/L levels in French rainwaters during Autumn season
27 Oct 2023 | J Environ Qual
This study analyzed rainwater in France for PFAS and detected the presence of PFNA, PFUnA, and PFHxA while also emphasizing the importance of environmental surveillance and improved analysis methods.
Environmental distribution of per-and polyfluoroalkyl substances (PFAS) on Svalbard: Local sources and long-range transport to the Arctic
23 Oct 2023 | Chemosphere
PFAS were found in various environmental samples along the west coast of the Norwegian Arctic with significant contributions from wastewater and a firefighting training site. Melting snow and ice during Arctic spring may also become an increasingly important PFAS source with climate warming.
Per- and Polyfluoroalkyl Substances (PFAS) in PubChem: 7 Million and Growing
23 Oct 2023 | Environ. Sci. Technol.
The Organisation for Economic Co-operation and Development's 2021 revision of the PFAS definition has led to the inclusion of over 7 million PFAS compounds in PubChem.
Dietary exposure to per- and polyfluoroalkyl substances: Potential health impacts on human liver
21 Oct 2023 | Sci Total Environ
PFAS contamination in food poses an especially elevated risk of liver toxicity to infants and adolescents and primarily comes from biomagnification through the food chain and food contact materials.
Perfluoroalkyl substances in umbilical cord blood and blood pressure in offspring: a prospective cohort study
19 Oct 2023 | Environmental Health
Exposure to certain long-chain PFAS, particularly PFOS, PFDA, and PFUA, in umbilical cord blood was associated with lower blood pressure in offspring at the age of 4 years, with PFUA being the most significant contributor and PFDoA exhibiting a positive association with blood pressure.
Metabolic Perturbations Associated with an Exposure Mixture of Per-and Polyfluoroalkyl Substances in the Atlanta African American Maternal-Child Cohort
19 Oct 2023 | Environ Sci Technol
Prenatal exposure to a mixture of PFAS chemicals, including PFOA, PFNA, PFOS, and PFHxS, is associated with significant metabolic perturbations indicative of systemic inflammation and oxidative stress in pregnant African-American women, highlighting the importance of considering the joint effects of these chemicals on human health.
Prenatal Exposure to Multiple Endocrine-Disrupting Chemicals and Childhood BMI Trajectories in the INMA Cohort Study
18 Oct 2023 | Environ Health Perspect
Exposure to HCB, DDE, PCBs, and PFNA was linked to an increased risk of lower birth size followed by accelerated BMI gain in single-exposure models.
Novel Insights into the Adverse Health Effects of per- and Polyfluoroalkyl Substances on the Kidney via Human Urine Metabolomics
18 Oct 2023 | Environ Sci Technol
Individuals with high occupational exposure to PFAS were found to have positive correlations with urinary PFAS levels to key small kidney molecules and to serum PFAS levels, suggesting that urine can be an indicator of the adverse effects of high PFAS exposure on kidney health and that urine PFAS levels can be a good indicator for serum levels.
