Analysis of per-and polyfluoroalkyl substances in plastic food storage bags by different analytical approaches
22 Nov 2023 | JCO
57% of plastic food storage bags were found to contain PFAS and migration studies showed no migration of diPAP (6:2) and rapid PFBS migration within 2 hours, with weekly exposure estimates remaining below the regulatory levels set by the European Food Safety Authority.
Validating blood microsampling for per-and polyfluoroalkyl substances quantification in whole blood
20 Nov 2023 | JCA
A minimally invasive and cost-effective microsampling technique was evaluated for quantifying 75 PFAS in dried blood spots, with the most effective extraction method identified as filtered protein precipitation, demonstrating its potential as an extensive and practical tool for large-scale human biomonitoring studies.
Tracing the Bioaccessibility of Per-and Polyfluoroalkyl Substances in Fish during Cooking Treatment
20 Nov 2023 | J. Agric. Food Chem.
Different methods of cooking reduced PFAS bioaccessibility, suggesting that steaming fish and reduced oil intake are beneficial for reducing PFAS absorption from fish consumption.
Per-and polyfluoroalkyl substances (PFAS) in Canadian municipal wastewater and biosolids: Recent patterns and time trends 2009 to 2021
19 Nov 2023 | Sci. Total Environ.
PFOS and PFOA remain in Canadian wastewater and biosolids, with concentrations of long-chain PFAS – except for PFOS – decreasing over time, while short-chain PFAS, used as replacements, show a consistent increase in wastewater between 2009 and 2021.
Distribution of select per- and polyfluoroalkyl substances at a chemical manufacturing plant
19 Nov 2023 | J Hazard Mater
Testing around a PFAS manufacturing facility in New Jersey revealed that while PFCAs were likely to migrate in groundwater, FTOHs primarily moved in the vapor phase, emphasizing the potential for PFAS vapor intrusion and indoor air inhalation exposure in the surrounding area.
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.
