This review summarizes current knowledge on trifluoroacetic acid, most notably its substantial increases in environmental samples over the past few decades.
Birth Outcomes in Relation to Prenatal Exposure to Per- and Polyfluoroalkyl Substances and Stress in the Environmental Influences on Child Health Outcomes (ECHO) Program
15 Mar 2023 | Environ Health Perspect
High levels of exposure to PFOA, PFOS, PFNA, and PFHxS were associated with lower birthweights in a large multi-cohort study.
The association of perfluoroalkyl substances (PFAS) exposure and kidney function in Korean adolescents using data from Korean National Environmental Health Survey (KoNEHS) cycle 4 (2018-2020): a cross-sectional study
15 Mar 2023 | Ann Occup Environ Med
Increased PFAS concentration was correlated with lower kidney function in high school students.
Perfluorooctanoic Acid (PFOA) Incorporated into Iron Particles Promoted the Formation of Disinfection Byproducts under Drinking Water Conditions
14 Mar 2023 | Environ Sci Technol
PFOA may interact with iron pipes to increase the formation of potentially hazardous chemicals in drinking water.
Evaluating Neutral PFAS for Potential Dermal Absorption from the Gas Phase
14 Mar 2023 | Environ Sci Technol
11 occupationally-relevant PFAS were estimated to be absorbed into the body more efficiently through dermal absorption than inhalation, suggesting that PFAS dermal absorption from the gas phase may need to be included in PFAS exposure guidelines.
Current per- and polyfluoroalkyl substance (PFAS) research points to a growing threat in animals
13 Mar 2023 | J Am Vet Med Assoc
Given the widespread PFAS exposure in livestock as well as pets, this review summarizes the current literature on PFAS in animals and discusses the implications for veterinary patients.
Ecotoxicity Evaluation of Fire-Extinguishing Water from Large-Scale Battery and Battery Electric Vehicle Fire Tests
13 Mar 2023 | Environ Sci Technol
The extinguishing water from vehicle fire tests found to be very toxic due to metals, PAHs, PFAS, and more, with most PFAS originating from the electric vehicle battery compared to the vehicle itself or conventional fuel.
Positive outcomes from U.S. lead regulations, continued challenges, and lessons learned for regulating emerging contaminants
10 Mar 2023 | Environ Sci Pollut Res Int
More proactive planning, communication, and research of common and persistent emerging contaminants of concern (i.e., PFAS) should be prioritized so that the same mistakes are not repeated.
Sex-Specific Bioaccumulation, Maternal Transfer, and Tissue Distribution of Legacy and Emerging Per- and Polyfluoroalkyl Substances in Snakes () and the Impact of Pregnancy.
7 Mar 2023 | Environ Sci Technol
Significant differences in PFAS concentrations and chemical compositions were found in pregnant females than in males and non-pregnant females, likely due to physiological changes during pregnancy.
Directly Fluorinated Containers as a Source of Perfluoroalkyl Carboxylic Acid
6 Mar 2023 | Environ. Sci. Technol. Lett.
Leaching experiments demonstrated that PFAS from fluorinated plastic containers can migrate into food, suggesting that regulatory action is warranted.
Association of perfluoroalkyl substances with pulmonary function in adolescents (NHANES 2007–2012)
4 Mar 2023 | ESPR
Exposure to PFNA may affect pulmonary function among adolescents aged 12–15 years.
Up in the air: Polyfluoroalkyl phosphate esters (PAPs) in airborne dust captured by air conditioning (AC) filters
4 Mar 2023 | Chemosphere
Polyfluoroalkyl phosphate esters accounted for over 90% of PFAS in AC filters located in school campuses and homes.
Invited Perspective: PFAS in Breast Milk and Infant Formula—It’s Time to Start Monitoring
2 Mar 2023 | EHP
The author states that health-based guidance values are needed for infant PFAS exposures for the myriad of legacy and emerging PFAS—not just the four drinking water screening values used in the U.S.
Emerging and Legacy Perfluoroalkyl Substances in Breastfed Chinese Infants: Renal Clearance, Body Burden, and Implications
2 Mar 2023 | Environ Health Perspect
Legacy and novel short-chain PFAS were found widespread in human breast milk, with 6:2 Cl-PFESA displaying a median half-life of 49 years in infants.
Per-and Polyfluoroalkyl Substances in Toilet Paper and the Impact on Wastewater Systems
1 Mar 2023 | ACS
Six PFAS were detected in toilet paper samples, and the most prevalent one, 6:2 diPAP, was estimated to contribute between 4% – 89% of 6:2 diPAP concentrations in sludge.
