• Spatial distribution and mass transport of Perfluoroalkyl Substances (PFAS) in surface water: A statewide evaluation of PFAS occurrence and fate in Alabama

  Science

  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

  Science

  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.

• ‘A worldwide public health threat’: Rob Bilott on his 20-year fight against forever chemicals

  News

  2 May 2022 | The Guardian

  Last month, an Ohio court certified a class action lawsuit brought by lawyer Rob Bilott that would cover 7 million people – and at some point possibly everyone living in the United States – who have been exposed to certain hazardous ‘forever chemicals.'

• Exposure to per- and Polyfluoroalkyl Substances and Markers of Liver Injury: A Systematic Review and Meta-Analysis

  Science

  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

  Science

  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

  Science

  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.

• Critical Review of Thermal Decomposition of Per- and Polyfluoroalkyl Substances: Mechanisms and Implications for Thermal Treatment Processes

  Science

  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.

• A Critical Review and Meta-Analysis of Impacts of Per- and Polyfluorinated Substances on the Brain and Behavior

  Science

  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.

• EU unveils plan for ‘largest ever ban’ on dangerous chemicals

  Policy

  26 Apr 2022

  Thousands of potentially harmful chemicals could soon be prohibited in Europe under new restrictions, which campaigners have hailed as the strongest yet.

• New England governors approve transformative laws on ‘forever chemicals’

  Policy

  26 Apr 2022

  The governors of two New England states have approved key pieces of legislation that transform their relationships with cancer-linked “forever chemicals” — by restricting their use on Maine farmland and facilitating treatment avenues for toxic exposure in Vermont.  

• Vermont PFAS Legislation and Litigation Updates

  Policy

  26 Apr 2022

  Two significant events have occurred out of Vermont in April 2022 involving PFAS issues – one on the litigation front and one on the legislative front.

• Army investigates PFAS chemical leak on Kwajalein base in Marshall Islands

  News

  26 Apr 2022 | Star and Stripes

  The Army is investigating the leak of about 380 gallons of a firefighting foam into the ground on Kwajalein Island in the Marshall Islands, Army Garrison-Kwajalein said in a newsletter published April 16.

• The California GeoTracker Database: A Unique Public Resource for Understanding Contaminated Sites

  Science

  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

  Science

  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

  Science

  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.
