Cleaning up Forever Chemicals in Construction: Informing Industry Change
7 Mar 2022 | MDPI
Given increased concerns around PFAS contamination in construction, the authors recommend the Environmental Protection Agency employ individuals with construction industry experience for stronger regulation and recommend that large organizations could be targeted by the sustainability rating schemes to speed up the management of PFAS.
Legacy and Emerging Per- and Polyfluoroalkyl Substances Behave Distinctly in Spatial Distribution and Multimedia Partitioning: A Case Study in the Pearl River, China

Environmental exposure to low-dose perfluorohexanesulfonate promotes obesity and non-alcoholic fatty liver disease in mice fed a high-fat diet
7 Mar 2022 | Environ Sci Pollut Res Int
Environmental PFHxS exposure is a likely risk factor for metabolic diseases such as non-alcoholic fatty liver disease, especially among obese individuals.
An Outdoor Aging Study to Investigate the Release of Per- And Polyfluoroalkyl Substances (PFAS) from Functional Textiles
28 Feb 2022 | ES&T

[Invited Perspective] Current Breast Milk PFAS Levels in the United States and Canada Indicate Need for Additional Monitoring and Actions to Reduce Maternal Exposures
28 Feb 2022
Addressing the higher breast milk concentrations from maternal exposure to PFAS in drinking water will require identifying contaminated drinking water sources and establishing health-protective PFAS drinking water guidelines that consider both exposures and risks to breastfed infants.
Comparative Toxicity of Aquatic PFAS Exposure in Three Species of Amphibians
28 Feb 2022 | Environ Toxicol Chem
Chronic exposure to PFOS, PFOA, PFHxS, and 6:2 FTS can negatively affect amphibian body condition and development at low concentrations.
Current Breast Milk PFAS Levels in the United States and Canada: After All This Time, Why Don't We Know More?
28 Feb 2022 | Environ Health Perspect
The authors emphasize the need to study PFAS in breast milk and found that all average estimated and measured breast milk PFOA and PFOS concentrations exceeded drinking water screening values for children, sometimes by more than two orders of magnitude.
Maternal Perfluorinated Compound Exposure and Risk of Early Pregnancy Loss: A Nested Case-control Study
28 Feb 2022 | Biomed Environ Sci
Higher maternal serum concentrations of PFDA and PFUdA were associated with an elevated risk of early pregnancy loss within 12 weeks of gestation.
Association between maternal per- and polyfluoroalkyl substance exposure and newborn telomere length: Effect modification by birth seasons
28 Feb 2022 | Environ Int
A higher maternal PFOA concentration was significantly associated with shorter newborn telomere length in spring-born infants but not in those born in other seasons.
Early Warnings by Liver Organoids on Short- and Long-Chain PFAS Toxicity
28 Feb 2022 | Toxics
Short-chain PFAS were found to reduce the structural integrity and disrupt normal cell functions in a synthetic tissue model.
Evaluation and validation of methodologies for the extraction of per- and polyfluoroalkyl substances (PFASs) in serum of birds and mammals
28 Feb 2022 | Anal Bioanal Chem
Protein precipitation and enhanced matrix removal were found to be fast and effective methodologies for the extraction of PFAS from low volumes of serum.
From cohorts to molecules: Adverse impacts of endocrine disrupting mixtures
21 Feb 2022 | Science
A mixture of endocrine-disrupting chemicals identified in pregnant women, including PFAS, phthalates, and BPA, were found to cause abnormalities in two model organisms and may also be associated with language delay in humans.
