Lithium-ion battery components are at the nexus of sustainable energy and environmental release of per- and polyfluoroalkyl substances
8 Jul 2024 | Nature
A cradle to grave evaluation of PFAS in lithium ion batteries found contamination near manufacturing sites from PFAS with similar ecotoxicity and treatability to PFOA, a highly toxic legacy PFAS. This work underscores the importance of lifecycle impacts when evaluating low-carbon energy technologies.
Impacts of rapidly urbanizing watershed comprehensive management on per-and polyfluoroalkyl substances pollution: based on PFAS “diversity” assessment
8 Jul 2024 | Water Research
In rapidly urbanizing Shenzhen, China, watershed comprehensive management failed to reduce overall PFAS pollution and diversity, often exacerbating contamination through river sediment dredging, though it improved point source pollution and revealed new high-risk PFAS, highlighting the need for better regulatory measures.
A Decade of Data and Hundreds of Analytes: Legacy and Emerging Chemicals in North American Herring Gull Plasma
8 Jul 2024 | Chemosphere
Between 2010 and 2021, 199 herring gull serum samples from the Great Lakes were analyzed for various pollutants, revealing a significant decrease in regional concentrations of PFAS, PCBs, PBDEs, and pesticides, though PFAS emerged as the dominant contaminant, with PCBs still posing a threat near certain areas.
Chemical threats for the sentinel Pygoscelis adeliae from the Ross Sea (Antarctica): Occurrence and levels of persistent organic pollutants (POPs), perfluoroalkyl substances (PFAS) and mercury within the largest marine protected area worldwide
7 Jul 2024 | Sci Total Environ
A study of unhatched Adélie penguin eggs from the Ross Sea Marine Protected Area in Antarctica revealed ongoing presence of legacy pollutants and the first detection of PFAS, underscoring the need for continued monitoring to assess the effectiveness of conservation efforts against human impacts.
Adsorption behaviors of perfluorooctanoic acid on aged microplastics
6 Jul 2024 | Water Environ. Res.
Aged microplastics can adsorb PFAS, like PFOA, with the process influenced by environmental factors such as salinity and dissolved organic matter, underscoring the need for more research on these interactions in real-world conditions.
Effects of functional groups of polyfluoroalkyl substances on their removal by nanofiltration
3 Jul 2024 | Water Research X
Nanofiltration membranes effectively remove PFAS, pharmaceuticals, and personal care products from drinking water, though the efficiency varies based on individual chemical properties.
Combining Freshwater Irrigation with Vegetable Selection to Mitigate the Occurrence of Per-and Polyfluoroalkyl Substances in Edible Vegetable Parts in a Semiarid Farmland in Northwestern China
2 Jul 2024 | ACS ES&T Water
Reclaimed-water irrigation can introduce PFAS into farmlands, but switching to freshwater irrigation reduces PFAS levels in vegetables, with carrots and potatoes accumulating fewer contaminants than cabbage and pak choi, highlighting the importance of cleaner irrigation water for growing nonleafy vegetables.
Non-target discovery and risk prediction of per- and polyfluoroalkyl substances (PFAS) and transformation products in wastewater treatment systems
2 Jul 2024 | J Hazard Mater
Wastewater treatment plants are recipients of PFAS wastes; researchers identified 896 PFAS and transformation products in both aqueous and sludge phases in Guangzhou, China.
[Report] Practices to Identify and Mitigate PFAS Impacts on Highway Construction Projects and Maintenance Operations
1 Jul 2024 | National Academies of Sciences
39% of surveyed states have procedures for identifying and mitigating PFAS contamination, 21% have encountered PFAS on projects, 30% are considering remediation, and 11% conduct testing, highlighting significant state-level efforts and challenges in managing PFAS impacts in highway construction and maintenance.
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.
