Profiling research on PFAS in wildlife: Systematic evidence map and bibliometric analysis
24 Jan 2024 | Ecol. solut. evid.
A comprehensive review of over 580 publications on PFAS in wildlife identified a linear increase in research from 2001 to 2021 covering 1042 species from 26 taxonomic classes, and emphasized the need for further exploration of new-generation PFAS, assessment in mid- and low-income countries, and more long-term studies.
A systematic review of contaminants in donor human milk
24 Jan 2024 | Matern Child Nutr
This systematic review examines the contaminants present in donor human milk for preterm and critically ill infants, revealing that bacterial species, environmental pollutants, and chemical substances such as PFAS were commonly found, emphasizing the need for standardized assessments and further research to understand the impact of donated milk contaminants on infant health outcomes.
Citizens’ opinions on (non-) essential uses of persistent chemicals: A survey in seven European countries
22 Jan 2024 | Environ Sci Policy
EU citizens were surveyed regarding essential and non-essential uses of PFAS, revealing diverse opinions, with safety-related PFAS applications considered essential while recreation and personal care uses are often viewed as non-essential.
Occurrence and pattern of legacy and emerging per-and Poly-FluoroAlkyl substances (PFAS) in eggs of loggerhead turtle Caretta caretta from western Mediterranean
22 Jan 2024 | Environ. Pollut.
Many PFAS were found in loggerhead turtle eggs off the coast of Italy, including emerging PFAS, and the highest concentrations in some eggs may be due to fluoropolymer-based marine litter that turtles may ingest.
Association between per- and polyfluoroalkyl substances and sex hormone levels in males based on human studies
22 Jan 2024 | Ecotoxicol Environ Saf
In a meta-analysis of 12 studies involving 7506 participants, exposure to PFNA and PFOA was found to be negatively correlated with male testosterone levels, emphasizing the need to consider these chemicals as potential risk factors for male reproductive health.
Evaluation of per- and polyfluoroalkyl substances (PFAS) released from two Florida landfills based on mass balance analyses
21 Jan 2024 | Waste Manag
The PFAS mass flux leached from disposed solid waste was found to be approximately 1-3% of the total amount, with the majority captured by leachate collection systems. These results may help prioritize waste management strategies and PFAS treatments over an estimated release period of at least 40 years.
Elevated levels of serum per-and poly-fluoroalkyl substances (PFAS) in contact lens users of US young adults
16 Jan 2024
Analysis of NHANES data revealed that contact lens users in the U.S. young adult population, particularly females, exhibit higher serum concentrations of PFAS such as PFOA and PFOS, suggesting that contact lens use may contribute significantly to PFAS body burden and pose a potential public health concern.
Occurrence of perfluoroalkyl substances in canned tuna and their impact on food safety
16 Jan 2024 | Food Control
The study highlights the potential risk of food contamination from PFAS, particularly in canned tuna, emphasizing concerns about their toxicity as endocrine disruptors, immunosuppressants, and carcinogens, with detected PFOS and PFNA levels below the established Tolerable Weekly Intake for the average Italian consumer but posing a potential concern for high consumers due to multiple sources of PFAS intake.
Tree barks for retrospective measurement and source appointment of airborne perfluoroalkyl and polyfluoroalkyl substances
16 Jan 2024 | Environ. Pollut.
Tree bark was found to be a valuable bioindicator for assessing airborne PFAS pollution, offering a long-term perspective on historical PFAS emissions and allowing for the characterization and tracking of sources, as demonstrated in a study of eight cities in southern Jiangsu Province, China.
Evaluating the toxicokinetics of some metabolites of a C6 polyfluorinated compound, 6: 2 fluorotelomer alcohol in pregnant and nonpregnant rats after oral exposure to the parent compound
16 Jan 2024 | FCT
Following oral exposure, both pregnant and nonpregnant rats exhibited potential biopersistence of 6:2 fluorotelomer alcohol (6:2 FTOH) and its metabolites, particularly 5:3 fluorotelomer carboxylic acid (5:3A), highlighting the need for additional research on human health implications.
Per/Polyfluoroalkyl Substances (PFASs) in a Marine Apex Predator (White Shark, Carcharodon carcharias) in the Northwest Atlantic Ocean
14 Jan 2024 | ACS Environmental Au
This study highlighted the accumulation of PFAS in plasma and muscle tissue of white sharks in the Northwest Atlantic Ocean far from pollution sources and noted some geographical differences in PFAS body burdens that may be due to differences in the diet among these distinct shark populations.
Maternal serum concentrations of per- and polyfluoroalkyl substances and childhood acute lymphoblastic leukemia
13 Jan 2024 | JNCI
Maternal exposure to certain PFAS during pregnancy, particularly MeFOSAA, is associated with an increased risk of childhood acute lymphoblastic leukemia, with notable connections to elevated levels of PFOS, suggesting a potential link between these environmental chemicals and the development of the most common childhood cancer.
Passive Sampler Derived Profiles and Mass Flows of Perfluorinated Alkyl Substances (PFASs) across the Fram Strait in the North Atlantic
10 Jan 2024 | Environ. Technol. Lett.
PFAS were found at different depths across the Fram Strait, showing long-range marine transport and suggesting that PFAS in the Arctic are governed by a feedback loop between the Atlantic and Arctic oceans as well as atmospheric transport.
