• Release of soil colloids during flow interruption increases the pore-water PFAS concentration in saturated soil

  Science

  11 May 2021 | Env Poll

  Removal of colloids from water samples can underestimate PFAS concentration.

• Occurrence, profiles, and ecotoxicity of poly- and perfluoroalkyl substances and their alternatives in global apex predators: A critical review

  Science

  11 May 2021 | J of Env Sci

  PFOS was the dominant PFAS found in the top predators, followed by PFUnDA, and the proportions of odd C-chain length PFCAs were higher than adjacent even C-chain length PFCAs.

• Perfluoroalkyl substances in drinking water sources along the Yangtze River in Jiangsu Province, China: Human health and ecological risk assessment

  Science

  11 May 2021 | Ecotoxicol Environ Saf

  PFOS, PFOA, and PFBS induced considerable risk on human health and aquatic species.

• Spatial and temporal baseline of perfluorooctanesulfonic acid retained in sediment core samples from Puget Sound, Washington, USA

  Science

  11 May 2021 | Mar Pollut Bull

  Sediments adjacent to Seattle, WA, had the largest PFOS flux, beginning in 1959.

• Per and polyfluoroalkyl substances (PFAS) at high concentrations in neonatal Australian pinnipeds

  Science

  5 May 2021 | Sci. Tot. Env.

  The geographical foraging range is the suspected factor for interspecies differences in marine mammals.

• Diffusion of perfluoroalkyl acids through clay-rich soil

  Science

  4 May 2021 | J Contam Hydrol

  Surface diffusion serves a potentially important role for strongly sorbing PFAAs in clay-rich soils.

• Microwave regeneration of granular activated carbon saturated with PFAS

  Science

  4 May 2021 | Water Res

  Multiple cycles of microwave treatments were found to successfully regenerate activated carbon saturated with PFOA and PFOS.

• Occurrence of per- and polyfluoroalkyl substances (PFASs) in wastewater of major cities across China in 2014 and 2016

  Science

  4 May 2021 | Chemosphere

  Population density and per capita gross domestic product have positive correlations with the concentration of PFBA, PFOA, PFHxA, and total-PFAS in wastewater.

• Immunotoxicity of Per-and Polyfluoroalkyl Substances: Insights into Short-Chain PFAS Exposure

  Science

  3 May 2021 | Toxics

  Understudied PFAS have toxicological potential but require additional investigation across endpoints and species, including humans, to understand health effects via drinking water exposure.

• PFAS paper mill settlement reflects growing trend

  News

  28 Apr 2021 | National Law Review

  Just a few days ago, an $11.9 million settlement was announced in a Michigan lawsuit in which a class of approximately 3,000 plaintiffs alleged that a PFAS manufacturer and a PFAS-using paper mill contaminated drinking water supplies, thereby polluting the environment and placing nearby citizens at increased risk of adverse health effects.

• EPA Administrator Regan Establishes New Council on PFAS

  Policy

  27 Apr 2021

  Administrator Michael S. Regan issued a memorandum to EPA’s senior leadership calling for the creation of a new “EPA Council on PFAS” that is charged with building on the agency’s ongoing work to better understand and ultimately reduce the potential risks caused by these chemicals. 

• Review on plant uptake of PFOS and PFOA for environmental cleanup: potential and implications

  Science

  27 Apr 2021 | Environ Sci Pollut Res Int

  This review provides an overview of current studies on plant uptake of PFOS and PFOA from the perspective of phytoremediation.

• Thermal Regeneration of Spent Granular Activated Carbon Presents an Opportunity to Break the Forever PFAS Cycle

  Science

  27 Apr 2021 | Environ Sci Technol

  This comprehensive review evaluates the past two decades of research on conventional thermal regeneration of activated carbon and critically analyzes and summarizes the literature on regeneration of PFAS-laden activated carbon.

• Perfluoroalkyl substances (PFASs) in the Ugandan waters of Lake Victoria: Spatial distribution, catchment release and public exposure risk via municipal water consumption

  Science

  27 Apr 2021 | Sci Total Environ

  PFAS were likely recycled from the industrially contaminated water and into municipal drinking water.

• Perfluorooctane sulfonate decreases the performance of a sequencing batch reactor system and changes the sludge microbial community

  Science

  27 Apr 2021 | Chemosphere

  Sequencing batch reactor wastewater treatment systems were found not to be suitable for PFOS removal, which should be addressed during pretreatment.
