PFAS and Phthalate/DINCH Exposure in Association with Age at Menarche in Teenagers of the HBM4EU Aligned Studies
18 Aug 2023 | Toxics
Di(2-ethylhexyl) phthalate was linked to early onset of menstruation, whereas a limited to no such association was found with the three studied PFAS.
Determination of several PFAS groups in food packaging material from fast-food restaurants in France
14 Aug 2023 | Chemosphere
PFHxA, 6:2 FTS, and 6:2/6:2 diPAP were found in all fast-food packaging samples in France, along with many other PFAS found in certain samples.
Evaluation of sealants to mitigate the release of per-and polyfluoroalkyl substances (PFAS) from AFFF-impacted concrete: characterization and forecasting
14 Aug 2023 | Water Research X
Simulated rainfall scenarios indicate that sealing concrete surfaces previously contaminated with AFFF reduces the leaching of PFAS, while unsealed concrete surfaces could continue to release PFOS for a period of 15 years or more.
Prenatal and childhood exposure to per-/polyfluoroalkyl substances (PFASs) and its associations with childhood overweight and/or obesity: a systematic review with meta-analyses
14 Aug 2023 | Environ Health
The review revealed positive correlations between prenatal PFNA and BMI, between PFOA and BMI in children older than 3 years, as well as between prenatal PFNA and waist circumference. Negative associations were found between prenatal PFOS and BMI in children younger than 3 years and PFHxS and the risk of being overweight.
Human health risk-based soil generic assessment criteria of representative perfluoroalkyl acids (PFAAs) under the agricultural land use in typical Chinese regions
14 Aug 2023 | Environ Pollut
This study provides a technical reference for deriving soil generic assessment criteria for PFAAs and found that the dominant exposure pathway for PFBA and PFBS in some regions of China was vegetables and attached soil.
Invited Perspective: Per- and Polyfluoroalkyl Substances and Impaired Antibody Response to Vaccination-Who Is Affected?
14 Aug 2023 | Environ Health Perspect
The role of factors like age, adverse experiences, and different life stages in PFAS-exposure immunotoxicity is a critical unanswered question, particularly involving COVID-19 vaccine response in the limited study cohort in Andersson et al., 2023.
High Exposure to Perfluoroalkyl Substances and Antibody Responses to SARS-CoV-2 mRNA Vaccine-an Observational Study in Adults from Ronneby, Sweden
14 Aug 2023 | Environ Health Perspect
High levels of PFAS exposure were found not to impair the COVID-19 mRNA vaccine response for up to 6 months after the shot.
Persistent Organic Contaminants in Dust from the International Space Station
8 Aug 2023 | Environ. Sci. Technol. Lett.
Various compounds, such as PBDEs, OPEs, PAH, PFAS, and PCBs, were discovered in dust from the International Space Station, showing comparable levels to those on Earth; the elevated PFOA concentrations in ISS dust were thought to originate from onboard waterproofing, greases, and nonflammable materials.
Per- and Polyfluoroalkyl Substances (PFAS) and Lipid Trajectories in Women 45-56 Years of Age: The Study of Women's Health Across the Nation
8 Aug 2023 | Environ Health Perspect
Research conducted among midlife women revealed a correlation between specific PFAS and elevated cholesterol levels in the bloodstream, characterized by a distinctive pattern of rapid increase followed by a decrease.
Invited Perspective: PFAS and Dyslipidemia-The Perimenopausal Period as a Critical Time Window
8 Aug 2023 | Environ Health Perspect
Kang et al.'s discoveries align with numerous cross-sectional and longitudinal studies that consistently demonstrate connections between PFAS and disrupted cholesterol levels, a significant risk factor for cardiovascular diseases after menopause.
Aerobic Biotransformation and Defluorination of Fluoroalkylether Substances (ether PFAS): Substrate Specificity, Pathways, and Applications
7 Aug 2023 | Environ. Sci. Technol. Lett.
This study investigated the structure–biodegradability relationship for 12 different ether PFAS with a carboxylic acid headgroup in activated sludge.
[Discussion] Perfluorohexyloctane: Do we really need a PFAS for the treatment of Dry Eye Disease?
7 Aug 2023 | Sci. Total Environ.
The researchers argue that non-pharmacological strategies and traditional artificial tears, which lack environmental risks, should be tried as treatments before eye drops that are composed entirely of PFAS.
Microplastics as carriers of per-and polyfluoroalkyl substances (PFAS) in aquatic environment: Interactions and ecotoxicological effects
4 Aug 2023 | Water Emerging Contaminants & Nanoplastics
This review covers the PFAS sorption onto microplastics, the ecological consequences of ingesting PFAS-contaminated microplastics, and their synergistic effects on aquatic life.
Discussion. Has the human population become an sentinel for the adverse effects of PFAS contamination on wildlife health and endangered species?
2 Aug 2023 | Sci Total Environ
PFAS are detected in wildlife globally, with international efforts needed to restrict PFAS discharges into the environment and to clean up PFAS-contaminated sites in order to protect wildlife from chemical pollution and advance species conservation.
