Serum PFAS and Urinary Phthalate Biomarker Concentrations and Bone Mineral Density in 12-19 Year Olds: 2011-2016 NHANES
3 May 2022 | J. Clin. Endocr.
Certain PFAS and phthalates may be associated with reduced bone mineral density in adolescent males.
Spatial distribution and mass transport of Perfluoroalkyl Substances (PFAS) in surface water: A statewide evaluation of PFAS occurrence and fate in Alabama
2 May 2022 | Sci. Total Environ.
PFAS were detected in 88% of surface water samples, with short-chain PFAS accounting for the majority of the contamination.
Invited Perspective: PFAS and Liver Disease: Bringing All the Evidence Together
2 May 2022 | EHP
The evidence of liver toxicity due to PFAS exposure by Costello et al. underscores the urgent need for further research and for immediate and reasonable public health action.
Exposure to per- and Polyfluoroalkyl Substances and Markers of Liver Injury: A Systematic Review and Meta-Analysis
2 May 2022 | Environ Health Perspect
There is consistent evidence for PFAS liver toxicity from rodent studies, supported by associations of PFAS and markers of liver function in human studies.
Acute Toxicity of Eight Aqueous Film-Forming Foams to 14 Aquatic Species
2 May 2022 | Environ Sci Technol
Exposure to at least one PFAS-free AFFF was at least as toxic as exposure to the PFAS-containing AFFF in all aquatic species tested.
Plasma perfluoroalkyl substance exposure and incidence risk of breast cancer: A case-cohort study in the Dongfeng-Tongji cohort
2 May 2022 | Environ Pollut
PFOA, PFHpA, and ΣPFCA concentrations were found to have a positive association with breast cancer risk, and the authors highlighted regulating PFAS as a chemical class for breast cancer prevention.
A Critical Review and Meta-Analysis of Impacts of Per- and Polyfluorinated Substances on the Brain and Behavior
2 May 2022 | Front Toxicol
This review summarizes concerns about PFAS accumulation in the brain, neurotoxicity, and PFAS exposure during development, and notes the lack of studies on realistic chronic PFAS exposure of low dose mixtures.
Critical Review of Thermal Decomposition of Per- and Polyfluoroalkyl Substances: Mechanisms and Implications for Thermal Treatment Processes
2 May 2022 | Environ Sci Technol
This review discusses thermal treatment as a way to destroy PFAS, and highlights that a major weakness of existing studies is that they do not mimic the full-scale thermal treatment systems that are actually used for PFAS incineration.
The California GeoTracker Database: A Unique Public Resource for Understanding Contaminated Sites
26 Apr 2022 | Ground Water Monit Remediat
This paper describes the origins of California’s GeoTracker website and how it evolved to account for changes in regulatory priorities and illustrates how long-term commitment to the collection of environmental data can support the general public and regulatory and research communities.
Levels and Temporal Trends of Trifluoroacetate (TFA) in Archived Plants: Evidence for Increasing Emissions of Gaseous TFA Precursors over the Last Decades
26 Apr 2022 | ES&T
TFA concentrations in plants were found to increase over several decades, likely due to increasing anthropogenic emissions of TFA precursors. The very high persistence and mobility of TFA in the environment mean that TFA and its precursors should be considered for regulation.
Bioaccumulation and Translocation of 6: 2 Fluorotelomer Sulfonate, GenX, and Perfluoroalkyl Acids by Urban Spontaneous Plants
26 Apr 2022 | ACS ES&T Engineering
Several types of PFAS were found to accumulate in urban weeds, with higher PFAS concentrations in plants with smaller leaves and finer roots.
Characterizing firefighter's exposure to over 130 SVOCs using silicone wristbands: A pilot study comparing on-duty and off-duty exposures
26 Apr 2022 | Sci Total Environ
Firefighter exposure to PFOS was significantly higher while responding to fires compared to while off-duty, and high exposure to phthalates and flame retardants was also observed.
American oysters as bioindicators of emerging organic contaminants in Florida, United States
26 Apr 2022 | Sci Total Environ
All studied PFAS and phthalate esters were present in at least one oyster across three sites throughout Florida, and a human health risk assessment indicated low risk.
Association between serum per-and polyfluoroalkyl substances concentrations and common cold among children and adolescents in the United States
19 Apr 2022 | Environ. Int.
In children, blood concentrations of PFAS mixtures and individual PFAS were associated with higher odds of common cold, especially in males.
Widespread Occurrence of Non-Extractable Fluorine in Artificial Turfs from Stockholm, Sweden
19 Apr 2022 | Analytical Chemistry
Results suggest the use of polymeric organofluorine in artificial turf, such that the production, end-of-life, and microplastic concerns are greater than the risk to users.
