Occurrence of per-and polyfluoroalkyl substances (PFAS) in potable groundwater near military bases in South Korea
4 Mar 2025 | Environ. Sci. Technol. Lett.
Groundwater near U.S. military bases in South Korea is heavily contaminated with PFAS, particularly from aqueous film-forming foam , with some wells exceeding drinking water safety standards by hundreds of times, posing significant health risks.
Storm Daniel extreme flood event in Thessaly, Greece: Assessing the pollution status of the impacted coastal marine areas through extended screening of emerging contaminants using LC-TIMS-HRMS
4 Mar 2025 | Environ. Sci. Technol. Lett.
Storm Daniel’s extreme flooding in Thessaly, Greece, led to a significant increase in PFAS contamination in coastal waters and sediments, with legacy PFAS like PFOS and emerging compounds such as ADONA detected at elevated levels, primarily due to wastewater overflow and industrial facility damage.
Characterizing seasonal patterns, gas-particle partitioning, and potential sources of airborne per-and polyfluoroalkyl substances in Japan
4 Mar 2025 | Environ. Sci. Technol.
Airborne PFAAs and their precursors in Japan show seasonal variations, with PFCAs more abundant in warm months and PFSAs in colder months, primarily originating from aqueous film-forming foams, waste streams, and fluoropolymer manufacturing.
6:2 Fluorotelomer Ethoxylates in Human Serum and Residential Homes: A Growing Environmental Health Concern
4 Mar 2025 | Environ Sci Technol
6:2 Fluorotelomer ethoxylates (6:2 FTEOs), an emerging group of PFAS widely used in antifog products, were detected in house dust and the serum of pregnant women in South China, showing potential bioaccumulation risks and raising concerns about their environmental and human health impacts.
Sociodemographic drivers of waste management behaviors and public perceptions of environmental contaminants in coastal communities of Newfoundland, Canada
3 Mar 2025 | JEM
Awareness of PFAS was low among residents of Newfoundland's coastal communities, with only 33% recognizing these contaminants, and while household size and gender influenced awareness levels, there was no strong correlation between PFAS awareness and concern for environmental or health impacts. This suggests a need for targeted education to bridge the gap between knowledge and action.
A systematic review of methods for the analysis of total per-and polyfluoroalkyl substances (PFAS)
1 Mar 2025 | Sci. Total Environ.
Results show wide variability in detection limits and concentrations across different sample types and regions identifying a need for improved standardization of instrumental methods and reporting.
Forever Chemicals (PFAS): An Overview for Maternity and Pediatric Health Care Professionals
1 Mar 2025 | MCN Am J Matern Child Nurs
Healthcare workers, especially those exposed to PFAS through medical supplies and occupational settings, face increased health risks, while pregnant individuals exposed to these chemicals may experience complications such as gestational hypertension, preeclampsia, and decreased birth weight in infants, highlighting the urgent need for monitoring and risk reduction strategies.
Exposure to per‐and polyfluoroalkyl substances in residential settled dust and risk of childhood acute lymphoblastic leukemia
24 Feb 2025 | IJC
Exposure to a mixture of eight PFAS detected in household dust, particularly EtFOSAA, was associated with an increased risk of childhood acute lymphoblastic leukemia, highlighting residential dust as a potential source of PFAS exposure linked to cancer risk.
Sand dollars (Mellita quinquiesperforata): A new bioindicator for tracking PFAS in coastal waters
24 Feb 2025 | Mar. Pollut. Bull.
Sand dollars were found to serve as reliable indicators of PFAS pollution in coastal sediments, as they bioaccumulate these harmful chemicals, with the highest concentrations detected near pollution sources like MacDill Air Force Base and Albert Whitted Airport in Tampa Bay, Florida.
Bioaccumulation and transfer of legacy and emerging per-and polyfluoroalkyl substances throughout the lifecycle of a tropical amphibian species Fejervarya limnocharis
21 Feb 2025 | Environ. Sci. Technol.
PFAS were detected throughout the lifecycle of the tropical frogs Fejervarya limnocharis, with high concentrations in eggs that decreased in tadpoles and remained stable in juvenile and adult frogs, while specific PFAS with low tendency to bind to proteins showed greater accumulation in tadpoles, suggesting different bioaccumulation patterns influenced by developmental stage and exposure pathways.
Screening estimates of bioaccumulation factors for 4950 per- and polyfluoroalkyl substances in aquatic species
20 Feb 2025 | J Hazard Mater
A machine learning model predicted bioaccumulation factors (BAFs) for 4,950 PFAS in 54 global edible fish species, revealing that PFAS with multiple functional groups tend to accumulate more, freshwater fish generally have higher BAFs than marine fish. An online tool was developed to support environmental risk assessment and policy decisions.
Association between PFAS exposure and metabolic-related biomarkers in Spanish adolescents
18 Feb 2025 | Environ Res
Exposure to PFAS chemicals in Spanish teenage boys was linked to higher blood sugar, cholesterol, and blood pressure, and the combination of different PFAS types affected liver health, with a hormone called kisspeptin possibly playing a role.
Minimizing the use of per-and polyfluoroalkyl substances for textured wetting-resistant surfaces.
17 Feb 2025 | Environ. Sci. Technol.
Textured surfaces made with materials, like polydimethylsiloxane and springtail-inspired structures, were found to have water- and oil-repellent properties similar to those of PFAS, offering alternatives for applications like water purification and self-cleaning textiles.
