• Associations of Prenatal Per- and Polyfluoroalkyl Substance (PFAS) Exposures with Offspring Adiposity and Body Composition at 16-20 Years of Age: Project Viva

  Science

  6 Dec 2023 | Environ Health Perspect

  Prenatal exposure to PFAS impacted the body weight and composition of teenagers, finding that higher concentrations of these substances were associated with an increased risk of obesity and altered BMI trajectories during late adolescence.

• Per- and polyfluoroalkyl substances (PFAS) in little penguins and associations with urbanisation and health parameters

  Science

  4 Dec 2023 | Sci Total Environ

  Tasmania penguins were found to be exposed to PFAS, with higher concentrations near urbanized breeding sites, resulting in potential health risks such as sex-specific associations with blood cell development and function.

• Prenatal exposure to Per-and polyfluoroalkyl substances and adiposity measures of children at 4 and 6 years: A prospective birth cohort in China

  Science

  1 Dec 2023 | Ecotoxicol Environ Saf

  Exposure to PFAS during pregnancy was linked to increased adiposity in Chinese children at ages 4 and 6, with a stronger impact on measures like arm circumference and waist circumference, particularly among girls.

• Association between probiotic consumption and serum perfluoroalkyl and polyfluoroalkyl substances (PFAS): results from NHANES, 2003–2018

  Science

  28 Nov 2023 | Environ. Sci. Eur.

  The consumption of probiotics through yogurt or supplements is associated with lower levels of certain PFAS, suggesting potential health benefits.

• Characterizing the Movement of Per-and Polyfluoroalkyl Substances in an Avian Aquatic–Terrestrial Food Web

  Science

  24 Nov 2023 | Environ. Sci. Technol.

  Tree swallow nestlings were found to feed on both terrestrial and aquatic macroinvertebrates, leading to the bioaccumulation and biomagnification of PFAS, particularly PFOS, highlighting the complex and chemical-specific movement of PFAS through linked aquatic-terrestrial food webs.

• Exposure to perfluoroalkyl substances and longitudinal changes in bone mineral density in adolescents and young adults: A multi-cohort study

  Science

  23 Nov 2023 | Environ Res

  Exposure to PFOS was found to be associated with lower bone mineral density in both Hispanic adolescents and mixed-ethnicity young adults, suggesting potential long-term impacts on bone health and increased risk of osteoporosis in adulthood.

• Per-and polyfluoroalkyl substances (PFAS) in Canadian municipal wastewater and biosolids: Recent patterns and time trends 2009 to 2021

  Science

  19 Nov 2023 | Sci. Total Environ.

  PFOS and PFOA remain in Canadian wastewater and biosolids, with concentrations of long-chain PFAS – except for PFOS – decreasing over time, while short-chain PFAS, used as replacements, show a consistent increase in wastewater between 2009 and 2021.

• Per- and poly-fluoroalkyl substances in commercial organic eggs via fishmeal in feed

  Science

  7 Nov 2023 | Chemosphere

  Organic eggs from certain farms in Denmark were found to contain elevated levels of PFAS originating from fishmeal used in organic feed, leading to the voluntary removal of fishmeal from the feed by producers to mitigate PFAS exposure.

• Prevalence and Source Tracing of PFAS in Shallow Groundwater Used for Drinking Water in Wisconsin, USA

  Science

  2 Nov 2023 | Environ Sci Technol

  Human waste sources, septic systems in particular, are important sources of PFAAs, especially ones with 8 or less perfluorinated carbons, in shallow groundwater.

• Exposure to perfluoroalkyl and polyfluoroalkyl substances and pediatric obesity: a systematic review and meta-analysis

  Science

  31 Oct 2023 | Int J Obes (Lond)

  The review investigated the potential impact of PFAS on childhood obesity. It observed a possible inverse relationship between postnatal PFAS exposure and changes in body mass index though the review was limited by the small number of studies.

• Chemical crisis: The unseen toxic threat contaminating wildlife worldwide

  News

  28 Oct 2023 | The Hill

  An unseen but growing chemical contamination crisis is threatening wildlife across all seven continents, exacerbating a host of environmental threats they’re already facing. 

• Trends in Serum Per-and Polyfluoroalkyl Substance (PFAS) Concentrations in Teenagers and Adults, 1999–2018 NHANES

  Science

  27 Oct 2023 | Int. J. Environ. Res. Public Health

  Some longer chain PFAS levels in serum have decreased over time, however they are still detected in drinking water and consumer products, with certain racial/ethnic groups showing differing levels of exposure, highlighting the need for continued monitoring.

• Per- and Polyfluoroalkyl Substances (PFAS) in PubChem: 7 Million and Growing

  Science

  23 Oct 2023 | Environ. Sci. Technol.

  The Organisation for Economic Co-operation and Development's 2021 revision of the PFAS definition has led to the inclusion of over 7 million PFAS compounds in PubChem.

• Metabolic Perturbations Associated with an Exposure Mixture of Per-and Polyfluoroalkyl Substances in the Atlanta African American Maternal-Child Cohort

  Science

  19 Oct 2023 | Environ Sci Technol

  Prenatal exposure to a mixture of PFAS chemicals, including PFOA, PFNA, PFOS, and PFHxS, is associated with significant metabolic perturbations indicative of systemic inflammation and oxidative stress in pregnant African-American women, highlighting the importance of considering the joint effects of these chemicals on human health.

• Environmental exposure to legacy and emerging per- and polyfluoroalkyl substances and endometriosis in women of childbearing age

  Science

  14 Oct 2023 | Sci. Total Environ.

  PFOA and certain PFOS isomers were positively associated with an increased risk of endometriosis.
