• Sequestration and potential release of PFAS from spent engineered sorbents

  Science

  14 Oct 2020 | Sci of Tot Env

  Used water filters were found to potentially be a secondary source of PFAS contamination.

• Consumption of freshwater fish: a variable but significant risk factor for PFOS exposure

  Science

  14 Oct 2020 | Environ Res

  Despite highly variable PFOS concentrations in fish from different sites, the three most commonly consumed freshwater species in Sweden constitute an important source for the total annual intake even for people who eat this kind of fish only a few times per year.

• Policy, health, and justice—focus of October meeting on PFAS contaminants in drinking water

  Policy

  13 Oct 2020

  The University of Rhode Island STEEP Superfund Research Center is hosting a conference, “PFAS In Our World: What We Know and What We Can Do,” October 13 and 14, 2020.

• [Report] Furthering Understanding of Emissions from Landfilled Waste Containing POP BFRs and PFASs (FUEL)

  Science

  13 Oct 2020 | EPA Res.

  The FUEL project measured brominated flame retardants and PFAS in leachate from landfills and collected air, soil, and groundwater samples traceable to these landfills.

• Demographic and exposure characteristics as predictors of serum per- and polyfluoroalkyl substances (PFASs) levels - A community-level biomonitoring project in Pennsylvania

  Science

  13 Oct 2020 | Int J Hyg Environ Health

  PFAS serum levels were associated with sex, age, employment in the study area, the quantity of daily tap water consumption, and length of residence in the study area.

• Per- and Polyfluoroalkyl Substances (PFAS) in Surface Water Near US Air Force Bases: Prioritizing Individual Chemicals and Mixtures for Toxicity Testing and Risk Assessment

  Science

  13 Oct 2020 | Environ Toxicol Chem

  Data science was applied to characterize and prioritize PFAS and PFAS mixtures from a large dataset of PFAS measurements in surface waters associated with U.S. Air Force Installations with a history of aqueous film-forming foams use.

• Are Fluoropolymers Really of Low Concern for Human and Environmental Health and Separate from Other PFAS?

  Science

  12 Oct 2020 | ES&T

  Given fluoropolymers’ extreme persistence; emissions associated with their production, use, and disposal; and a high likelihood for human exposure to PFAS, their production and uses should be curtailed except in cases of essential uses.

• Levels of per- and polyfluoroalkyl substances (PFAS) in ski wax products on the market in 2019 indicate no changes in formulation

  Science

  7 Oct 2020 | Environ Sci Process Impacts

  Analysis of eleven of the best-selling fluorinated ski wax products found that although some indicated that they have switched short-chain PFAS they are continuing to use long-chain varieties.

• Perfluorooctanesulfonic acid (PFOS) and perfluorohexanesulfonic acid (PFHxS) alter the blood lipidome and the hepatic proteome in a murine model of diet-induced obesity.

  Science

  7 Oct 2020 | Toxicol. Sci.

  PFOS and PFHxS were found to increase the risk of metabolic and inflammatory disease when a diet high in fat was consumed.

• First report on the sources, vertical distribution and human health risks of legacy and novel per- and polyfluoroalkyl substances in groundwater from the Loess Plateau, China

  Science

  6 Oct 2020 | J Haz. Mat.

  In the Loess Plateau, both industrial and agricultural activities have contributed to PFAS pollution with short-chain alternatives replacing legacy compounds.

• Intrauterine Exposure to Per- and polyfluoroalkyl substances May Harm Children's Lung Function Development

  Science

  6 Oct 2020 | Environ. Res.

  PFOA, PFOS, PFNA, and PFUA were higher in cord blood than in serum from eight-year-olds suggesting that they may play a vital role in lung development.

• A Critical Review of A Recommended Analytical and Classification Approach for Organic Fluorinated Compounds with an Emphasis on Per- and Polyfluoroalkyl Substances (PFAS).

  Science

  6 Oct 2020

  A review of the current methods to both detects the presence of fluorine and specific PFAS to better help regulators identify public health or environmental hazards.

• Emerging and Legacy Per- and Polyfluoroalkyl Substances in House Dust from South China: Contamination Status and Human Exposure Assessment.

  Science

  6 Oct 2020 | Environ. Res.

  Analysis based on compositions in house dust from East Asia, North America, and Europe were found to exhibit a region-specific indicating region-specific market demands, application patterns, as well as associated human exposure risks.

• Emerging Chlorinated Polyfluorinated Polyether Compounds Impacting the Waters of Southwestern New Jersey Identified by Use of Nontargeted Analysis

  Science

  5 Oct 2020 | ES&T L

  Nontargeted analysis was used to estimate the effectiveness of point-of-entry water treatment systems for removal of the emerging species and reduced the abundance of PFAS by >90%.

• AGs urge Congress to keep tough PFAS language in defense bill

  Policy

  5 Oct 2020

  Congressional leaders should advance legislation that would force the U.S. Department of Defense to comply with state laws regulating toxic “forever chemicals,” urged attorneys general in Michigan and 17 other states.
