Non-metal roofing materials as potential sources for pollutants-laboratory leaching studies on various roofing materials
24 Mar 2025 | J. Hazard. Mater.
PFAS were detected in leachate from several common non-metal roofing materials—such as fiber cement and bitumen shingles—indicating that rooftops may be an overlooked source of PFAS pollution in urban stormwater runoff.
Exposure to per-and poly-fluoroalkyl substances and respiratory and skin effects in children and adolescents: A systematic review and meta-analysis
19 Mar 2025 | J Hazard Mater
PFHxS was associated with an increased risk of atopic dermatitis, like eczema, in children, especially when exposure occurred during the prenatal period, suggesting that even early-life exposure to certain PFAS can impact immune and skin health.
Unraveling the Exposure Spectrum of PFAS in Fluorochemical Occupational Workers: Structural Diversity, Temporal Trends, and Risk Prioritization
18 Mar 2025 | Environ Sci Technol
Researchers analyzed the blood of fluorochemical plant workers in China and found 64 types of PFAS chemicals—including 15 previously unknown ones—with some linked to high health risks due to their persistence and ability to accumulate in the body, highlighting the need for stricter monitoring and regulation of these toxic substances.
High levels of flame retardants in vehicle dust indicate ongoing use of brominated and organophosphate flame retardants in vehicle interiors
15 Mar 2025 | Environ Monit Assess
PFAS were found at low but widespread levels in car interior dust—especially on dashboards—indicating their continued use in materials like stain-resistant coatings and plastics despite increasing regulations.
Ten years of PFOS and PFOA human biomonitoring in Italy: Exposure levels and determinants of exposure
14 Mar 2025 | Chemosphere
PFAS exposure in the Italian population has declined over ten years for PFOA but not for PFOS, with higher levels observed in men, individuals in urbanized areas, and those with higher education or occupational skill levels, while proximity to PFAS-emitting industries remains the strongest predictor of elevated exposure.
Estimating historical PFAS exposures in Ronneby, Sweden using biobanked dried blood spots from newborns
13 Mar 2025 | Environ Res
Researchers used newborn blood samples stored in Sweden's national biobank to show that residents of Ronneby were exposed to toxic PFAS chemicals from contaminated drinking water as early as 1985, with levels rising steadily until 2013 due to fire-fighting foam used at a nearby military airport.
Degree of food processing and serum poly- and perfluoroalkyl substance concentrations in the US National Health and Nutrition Examination Survey, 2003-2018.
10 Mar 2025 | Int J Hyg Environ Health
PFOA levels were associated with higher intake of processed and lower intake of unprocessed/minimally processed foods, suggesting that food contact materials, rather than the foods themselves, might be an important source of exposure to PFOA.
Prenatal per- and polyfluoroalkyl substances and blood pressure trajectories in the New Hampshire Birth Cohort Study
8 Mar 2025 | Int J Hyg Environ Health
Higher prenatal exposure to PFAS is associated with increased blood pressure during pregnancy, even among women without hypertension, suggesting that these chemicals may contribute to adverse maternal and child health outcomes.
Release of per-and polyfluoroalkyl substances from municipal and construction and demolition waste landfills and wastewater treatment plants in North Carolina
6 Mar 2025 | ACS ES&T Water
The presence of fluoroethers in the leachate from various landfills, as well as in wastewater treatment plants, illustrates that the impact of a fluorochemical plant and fluoropolymer production extends beyond the polymer manufacturing facility.
Differences in serum concentrations of per-and polyfluoroalkyl substances by occupation among firefighters, other first responders, healthcare workers, and other essential workers in Arizona, 2020-2023
6 Mar 2025 | J Expo Sci Environ Epidemiol
Firefighters and healthcare workers in Arizona had higher levels of certain PFAS chemicals in their blood compared to other essential workers, suggesting occupational exposure risks that may require further investigation and protective measures.
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.
