Per- and polyfluoroalkyl substances (PFASs) in the blood of police and Beagle dogs from Harbin, China: Concentrations and associations with hematological parameters
Science
28 Mar 2022 | Chemosphere
Dominant PFAS in the blood of dogs were found to be PFOA, PFBA, and PFOS, and PFAS exposure was linked to many changes in biochemical blood parameters like cholesterol.

Science
15 Mar 2022 | Reproductive Toxicology
PFHxS was found to induce morphological and molecular changes in developing cow reproductive cells at critical stages.

Environmental exposure to low-dose perfluorohexanesulfonate promotes obesity and non-alcoholic fatty liver disease in mice fed a high-fat diet
Science
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.

[Invited Perspective] Current Breast Milk PFAS Levels in the United States and Canada Indicate Need for Additional Monitoring and Actions to Reduce Maternal Exposures
Science
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
Science
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?
Science
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.

Monitoring breast milk for PFAS
News
24 Feb 2022 | Science Daily
While there is over 20 years of biomonitoring data on PFAS in human serum and urine, scientists and physicians have a limited understanding of the level of these chemicals in breast milk.

Risk of Cancer in a Community Exposed to Per- and Poly-Fluoroalkyl Substances
Science
20 Feb 2022 | Environ Health Insights
Merrimack residents experienced a significantly higher risk of at least 4 types of cancer between 2005 and 2014 which may be linked to PFAS-contaminated drinking water.

Release of perfluoroalkyl substances from AFFF-impacted concrete in a Firefighting Training Ground (FTG) under repeated rainfall simulations
Science
7 Feb 2022 | J. Hazard. Mater.
High concentrations of 5 PFAS were measured in concrete cores removed from firefighting training grounds, and simulated rainfall released approximately 1% of the total PFAS mass in the concrete surface layer, leading researchers to believe that concrete can be a secondary source of PFAS contamination.

CDC study finds higher-than-average PFAS blood levels in residents near New Castle Air National Guard Base
News
2 Feb 2022 | WHYY News
In 2014, the drinking water supply in the area was found to contain PFAS levels above Environmental Protection Agency standards.

Serum levels of perfluoroalkyl substances (PFAS) and body composition - A cross-sectional study in a middle-aged population
Science
1 Feb 2022 | Environ Res
PFOA, PFNA, and PFDA were inversely related to fat mass measurements in women but not men, while PFOS and PFHxS had no consistent associations with body composition.

Comparison of untargeted and targeted perfluoroalkyl acids measured in adolescent girls
Science
25 Jan 2022 | Chemosphere
Environmental exposure measures from untargeted assays are comparable with targeted assays, and can serve as reliable inputs into statistical analysis for discovery and for determining their biological impacts.

Background release and potential point sources of per-and polyfluoroalkyl substances to municipal wastewater treatment plants across Australia
Science
24 Jan 2022 | Chemosphere
About 60% of PFAS in Australian wastewater treatment plant influent was due to background release (at a rate of 8.1-24 μg/day/person) with the remaining ~40% due to point sources including industrial activities.

Demographic, life-style and physiological determinants of serum per- and polyfluoroalkyl substance (PFAS) concentrations in a national cross-sectional survey of Swedish adolescents
Science
17 Jan 2022 | Environ Res
Legacy PFAS were found at elevated levels throughout Swedish adolescents in addition to the novel 9Cl-PF3ONS in 5% of those tested, and females had lower serum PFAS concentration than males.

Quantitation of linear and branched perfluoroalkane sulfonic acids (PFSAs) in women and infants during pregnancy and lactation
Science
10 Jan 2022 | Environ Int
A linear relation between PFSA concentrations in mothers at pregnancy week 18 and infants at six months was observed, suggesting that pregnancy and lactation are major excretion routes for PFSA, but accumulate in the infant.
