Association between prenatal exposure to per-and polyfluoroalkyl substances and infant anthropometry: A prospective cohort study
4 Mar 2024 | Int. J. Hyg. Environ. Health
Prenatal exposure to PFAS was linked to altered infant growth patterns, with PFNA and PFDoA associated with increased size in females, and PFOA correlated with decreased weight, head, and arm circumference in males, suggesting potential impacts on offspring growth trajectories.
Prediction of the Interactions of a Large Number of Per- and Poly-Fluoroalkyl Substances with Ten Nuclear Receptors
29 Feb 2024 | Environ Sci Technol
Modeling and machine-learning was used to study interactions between thousands of PFAS and nuclear receptors – these interactions can be indicative of endocrine and metabolic disruption – and the authors urge biological validation of their computational findings on a diverse set of PFAS.
Unveiling per- and polyfluoroalkyl substance contamination in Chinese paper products and assessing their exposure risk
28 Feb 2024 | Environ Int
Chinese paper food contact materials were found to be contaminated with PFAS, with estimated intake from one-third of tested paper bowls/plates exceeding recommended health levels; moreover, the study suggests that microwave heating can release PFAS from popcorn bags and convert long-chain PFAS into short-chain forms.
Dynamic spatiotemporal changes of per- and polyfluoroalkyl substances (PFAS) in soil and eggs from private gardens at different distances from a fluorochemical plant
27 Feb 2024 | Environ Pollut
The study conducted near a fluorochemical plant in Antwerp, Belgium, revealed higher concentrations of short-chain PFAS and their precursors in vegetable garden soil, elevated levels of long-chain PFAS in chicken enclosure soil and homegrown eggs, and temporal variations such as a 9x decrease in PFOS concentrations in soil and a 13x drop in concentrations in eggs, emphasizing the presence of localized high-concentration plumes near the plant and the necessity for ongoing monitoring and regulatory intervention.
Integrated Analysis of Per-and Polyfluoroalkyl Substance Exposure and Metabolic Profiling of Elderly Residents Living near Industrial Plants
26 Feb 2024 | Environ. Sci. Technol.
Significant associations between PFAS exposure levels and metabolic profiles were identified among those residing near industrial plants, particularly within lipid metabolism pathways, shedding light on potential adverse health effects and emphasizing the importance of understanding and mitigating these risks.
Studies of Potential Migration of Hazardous Chemicals from Sustainable Food Contact Materials
26 Feb 2024 | Foods
Bio-based food packaging materials may still contain harmful contaminants like organophosphate esters and PFAS that may leach into food, especially baking papers purchased in Italy.
Changes in Concentrations of Polyfluoroalkyl Substances in Human Milk Over Lactation Time and Effects of Maternal Exposure via Analysis of Matched Samples
23 Feb 2024 | Environ. Sci. Technol.
Breast milk samples from 76 women post-delivery found certain PFAS compounds, particularly PFOA, PFOS, and N-MeFOSAA, with N-MeFOSAA being the highest in human milk at 3 months, suggesting an increase in PFAS concentrations in milk samples over time.
PFAS Promotes Disinfection Byproduct Formation Through Triggering Particle-bound Organic Matter Release in Drinking Water Pipes
21 Feb 2024 | Water Research
Trace PFAS in drinking water can trigger particles to release organic matter, which are precursors for disinfection byproduct formation, suggesting that water utilities should further explore the roles of loose deposit particles in drinking water.
Exposure to and Biomarker Responses From Legacy and Emerging Contaminants Along Three Drainages in the Milwaukee Estuary, Wisconsin, USA
20 Feb 2024 | Environ Toxicol Chem
Researchers analyzed legacy and emerging pollutants in tree swallow tissue and diet samples from the Milwaukee estuary, revealing relatively stable levels of bioaccumulative contaminants like polybrominated diphenyl ethers and PFAS, highlighting the need for heightened attention to PFAS exposure and its potential ecological impacts.
PFAS River Export Analysis Highlights the Urgent Need for Catchment-Scale Mass Loading Data
19 Feb 2024 | ES&T Letters
A study of a European river system found that wastewater treatment works contribute significantly to the total PFAS levels exported from the river, but that additional PFAS sources must also be eliminated in order to meet water quality improvement goals.
On the fluoropolymers and ultra-short PFAS topic: Aqueous Leaching of Ultrashort-Chain PFAS from (Fluoro)polymers: Targeted and Nontargeted Analysis
19 Feb 2024 | ES&T Letters
All tested fluoropolymers, as well as non-fluorinated alternatives like PEEK, were found to leach C2-C4 PFCAs, likely related to their production such as processing aids, residuals, and inhibitors. This indicates that fluoropolymers and other plastics can emit short chain PFAS into the environment.
Reproductive toxicity of PFOA, PFOS and their substitutes: A review based on epidemiological and toxicological evidence
17 Feb 2024 | Environ Res
PFAS are widely recognized for their reproductive toxicity, with substitutes proving equally or more harmful; this review covers potential reproductive toxicity mechanisms for PFAS in both males and females.
Transport and health risk of legacy and emerging per-and polyfluoroalkyl substances in the water cycle in an urban area, China: Polyfluoroalkyl phosphate esters are of concern
16 Feb 2024 | Sci Total Environ
PAPs are a harmful group of PFAS that cannot easily be removed by drinking water treatment, and were found to be transported via precipitation more than municipal wastewater discharge.
