Associations between co-exposure to Per- and Polyfluoroalkyl Substances and Organophosphate Esters and Erythrogram in Chinese Adults
1 Jul 2024 | Chemosphere
A study of 467 adults in Shijiazhuang, China found that PFAS, particularly PFHxS, significantly impact red blood cell indicators, more so than organophosphate esters, highlighting the need for further research on these effects.
The Total Mass of Per- and Polyfluoroalkyl Substances (PFASs) in California Cosmetics
27 Jun 2024 | Environ Sci Technol
Cosmetics sold in California were found to contain between 650 to 56,000 kg of PFAS annually, with the majority coming from shaving creams, hair care products, facial cleansers, sun care products, and lotions, contributing 4% to the PFAA load in wastewater treatment plants.
Emergency of per- and polyfluoroalkyl substances in drinking water: Status, regulation, and mitigation strategies in developing countries
26 Jun 2024 | EEH
This review discusses how the detection of PFAS in drinking water is a significant challenge for developing countries, necessitating urgent research and development of affordable removal techniques to address the serious health risks posed by these chemicals.
Landfill Gas: A Major Pathway for Neutral Per- and Polyfluoroalkyl Substance (PFAS) Release
26 Jun 2024 | ES&T L
A study of three landfills found that the mass of fluorine leaving as gas (32–76%) was comparable to the mass leaving as leachate (24–68%). FTOHs were the dominant (87–97%) total neutral PFAS constituents.
Exposure to per- and polyfluoroalkyl substances and alterations in plasma microRNA profiles in children
25 Jun 2024 | Environ Res
PFAS exposure in children is linked to changes in specific microRNAs, biomarkers related to chronic diseases such as cancer and inflammation, highlighting another pathway that these persistent chemicals may influence health risks.
Dermal bioavailability of perfluoroalkyl substances using in vitro 3D human skin equivalent models
24 Jun 2024 | Environ. Int.
In vitro modeling showed substantial dermal absorption of PFAS, with around 50% of short-chain PFAS absorbing through the skin and less absorption of larger PFAS, suggesting that dermal exposure could be a significant source of exposure.
Beyond water: Solution-focused communication and regulation are required to address per- and poly-fluoroalkyl substances pollution
21 Jun 2024 | One Earth
Evidence-based science communication and additional policy interventions are urgently needed to address widespread PFAS pollution.

19 Jun 2024 | Curr Environ Health Rep
This review examines the connection between maternal exposure to PFAS and perinatal depression, identifying 23 common metabolic pathways, and recommends future research on specific metabolic processes and longitudinal study designs to better understand these associations.
Bioconcentration of per- and polyfluoroalkyl substances and precursors in fathead minnow tissues environmentally exposed to aqueous film-forming foam-contaminated waters
19 Jun 2024 | Environ Toxicol Chem
Fathead minnows exposed to PFAS-contaminated groundwater at Joint Base Cape Cod showed increasing PFAS levels in their tissues over time, indicating potential pathways for PFAS exposure in aquatic wildlife and humans.
Perfluoroalkyl substances in the meat of Polish farm animals and game - Occurrence, profiles and dietary intake
17 Jun 2024 | Sci Total Environ
Meat from farm animals and game was analyzed for PFAS contamination, revealing that wild boar meat had the highest levels, with potential health risks from frequent consumption, while meat from livestock and deer posed negligible health concerns in Poland.
In silico prediction of the interaction of legacy and novel per- and poly-fluoroalkyl substances (PFAS) with selected human transporters and of their possible accumulation in the human body
17 Jun 2024 | Arch Toxicol
PFAS were examined through computer simulations, revealing that legacy PFAS like PFOA and PFOS have a higher propensity to interact with human proteins involved in chemical transportation and accumulation, suggesting a greater potential for bioaccumulation compared to newer PFAS formulations.
