Public perceptions of per-and polyfluoroalkyl substances (PFAS): Psycho-demographic characteristics differentiating PFAS knowledge and concern
27 Jan 2024 | J. Clean. Prod.
This study, conducted in Aotearoa New Zealand, highlights that nearly 45% of surveyed adults are aware of PFAS, with varying levels of understanding and concerns, revealing information gaps that could inform regulations, policies, and targeted education campaigns on PFAS.
PFAS ghosts: how to identify, evaluate, and exorcise new and existing analytical interference
27 Jan 2024 | Anal. Bioanal. Chem.
As awareness of PFAS grows globally and monitoring studies increase, the risk of analytical interference, leading to false PFAS detection ("seeing ghosts"), rises, emphasizing the need to address these issues for accurate assessments crucial to safeguarding human and environmental health.
Associations of dietary intake and longitudinal measures of per- and polyfluoroalkyl substances (PFAS) in predominantly Hispanic young Adults: A multicohort study
27 Jan 2024 | Environ Int
Dietary factors, such as tea & pork intake and eating food not prepared at home, were associated with increases in blood levels of PFAS in young Hispanic adults, underscoring the significance of diet in PFAS exposure and the need for monitoring food and beverage contamination.
Association between Perfluoroalkyl Substances in Follicular Fluid and Polycystic Ovary Syndrome in Infertile Women
26 Jan 2024 | MDPI
A clinical study revealed a positive relationship between PFOA levels in follicular fluid and increased odds of polycystic ovary syndrome, suggesting PFOA as a potential risk factor for this endocrine disease in women.
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.
