Suspect Screening and Chemical Profile Analysis of Stormwater Runoff Following 2017 Wildfires in Northern California
10 May 2022 | Environ Toxicol Chem
Stormwater runoff from the San Francisco Bay area was found to have increased levels of PFAS after seasonal wildfires leading to potential ecological risk.
How Well Do Product Labels Indicate the Presence of PFAS in Consumer Items Used by Children and Adolescents?
10 May 2022 | Environ Sci Technol
PFAS were detected in many products used by children and adolescents including clothing, face masks, mattress and pillow protectors, sheets, rugs, upholstery and menstrual underwear. PFAS were detected more often and at higher levels in products labeled as water- and stain-resistant.
Identification of Branched and Linear Forms of PFOA and Potential Precursors: A User-Friendly SMILES Structure-based Approach.
10 May 2022 | Front Environ Sci
A new computational toxicology method searched a database of over 10,700 structures and correctly classified PFOA and its related compounds as defined by the Stockholm Convention, with 100% sensitivity and 99.7% accuracy.
Serum PFAS and Urinary Phthalate Biomarker Concentrations and Bone Mineral Density in 12-19 Year Olds: 2011-2016 NHANES
10 May 2022 | J Clin Endocrinol Metab
Certain PFAS and phthalates may be associated with reduced bone mineral density in adolescent males, which may have implications for lifelong skeletal health.
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.
