• Human biomonitoring of per- and polyfluoroalkyl substances in German blood plasma samples from 1982 to 201

  Science

  21 Sep 2020 | Env. Int.

  A spectrum of 37 PFAS was determined in 100 human plasma samples from 2009 to 2019 with a significant portion of total PFOS analytes present that were branched isomers.

• Colorado testing fish in new push to prevent health harm from toxic “forever chemicals”

  News

  20 Sep 2020 | The Denver Post

  Efforts to contain PFAS reflect growing concerns about unregulated contaminants degrading groundwater, soil and drinking water. Fish can accumulate PFAS at concentrations up to 10,000 times higher than the already-elevated levels in groundwater and people eating toxic fish could face health harm.

• Air Force won’t follow NH’s new PFAS water safeguards

  News

  18 Sep 2020 | Seacoastonline.com

  U.S. Air Force officials said they will continue to follow the EPA’s “lifetime health advisory” for PFAS and not New Hampshire’s more protective standards.

• EU agency sets limit on PFAS in food

  News

  17 Sep 2020 | Chemical & Engineering News

  Recommended threshold applies to combined exposure to 4 PFAS, based on their ability to decrease people’s immune system response to vaccinations.

• [Press Release] PFAS in food: EFSA assesses risks and sets tolerable intake

  Policy

  17 Sep 2020

  When stetting the new, extremely low threshold for PFOS, PFOA, PFNA, and PFHxS, the European Food Safety Authority considered the decreased response of the immune system to vaccination as the most critical human health effect.

• Animal size impacts perfluoroalkyl acid (PFAA) concentrations in muscle tissue of estuarine fish and invertebrate species

  Science

  15 Sep 2020 | Env. Poll.

  Weight and PFAS concentrations were inversely related in estuarine and marine invertebrates.

• Legacy and Novel Per- and Polyfluoroalkyl Substances (PFAS) in Juvenile Seabirds from the US Atlantic Coast

  Science

  15 Sep 2020 | Environ Sci Technol .

  These results detail concentrations of legacy and novel PFAS across different marine ecosystems along the US Atlantic East Coast.

• Faster, on-site way to detect PFAS

  News

  15 Sep 2020 | Science Daily

  The only way to prevent PFAS entering the food chain, is to minimise or remove the chemicals from the environment -- making early detection a highly desirable part of this removal process.

• Association between exposure to perfluoroalkyl substances and metabolic syndrome and related outcomes among older residents living near a Science Park in Taiwan

  Science

  15 Sep 2020 | Int J Hyg Environ Health

  PFNA and PFOS were found to be positively associated with uric acid levels, especially in elderly males.

• Immunotoxicity of an Electrochemically Fluorinated Aqueous Film-Forming Foam

  Science

  14 Sep 2020 | Toxicol. Sci.

  Male mice exposed to PFAS-containing fire fighting foams saw a decrease in body weight by 15% and an increase of liver weight up to 200%.

• Perfluoroalkyl acids and sulfonamides and dietary, biological and ecological associations in peregrine falcons from the Laurentian Great Lakes Basin, Canada

  Science

  9 Sep 2020 | Environ. Res.

  The study's findings highlighted the importance of integrating dietary, biological, and ecological factors when studying PFAS exposure in birds.

• Neurotoxic Effects of Lactational Exposure to Perfluorooctane Sulfonate on Learning and Memory in Adult Male Mouse

  Science

  8 Sep 2020 | Food Chem Toxicol

  The present study showed that lactational PFOS exposure has a profound, long-lasting neurotoxic effect in the brain and consequently leads to learning and memory deficits.

• Legacy and emerging per- and polyfluoroalkyl substances (PFASs) in multi-media around a landfill in China: Implications for the usage of PFASs alternatives

  Science

  8 Sep 2020 | Sci. Total Environ.

  Short-chain PFAS such as PFBS was found in rising concentrations in surface waters replacing long-chain legacy PFAS.

• Effect of washing, soaking, and cooking methods on perfluorinated compounds in mackerel

  Science

  8 Sep 2020 | Food Sci Nutr

  Grilling and cooking with high starch foods was found to decrease PFAS concentrations in fish significantly.

• Legacy and alternative per- and polyfluoroalkyl substances in a subtropical marine food web from the Beibu Gulf, South China: Fate, trophic transfer and health risk assessment

  Science

  8 Sep 2020 | J. Hazard. Mater.

  PFOS and F-53B were found to biomagnify in marine ecosystems.
