[Perspective] Global Perspective on the Impact of Plastic Waste as a Source of Microplastics and Per-and Polyfluoroalkyl Substances in the Environment

8 Dec 2023 | ACS ES&T Water

Microplastics (MPs) and PFAS in the environment pose a serious threat to ecosystems and MPs act as carriers for PFAS, creating a secondary source of pollution–highlighting the need to better understand this interaction.

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

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.

Dose Response, Dosimetric, and Metabolic Evaluations of Replacement PFAS Perfluoro-(2, 5, 8-trimethyl-3, 6, 9-trioxadodecanoic) Acid (HFPO-TeA)

4 Dec 2023 | toxics

HFPO-TeA, a GenX replacement, was found to cause increased mortality rates in higher doses, body weight changes at lower doses, thyroid hormone disruptions, and evidence of a complex and toxic exposure-response in rats.

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

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 early childhood adiposity and cardiometabolic health in the Healthy Start study

2 Dec 2023 | IJO

Exposure to PFAS during pregnancy was found to be associated with increased body mass in early childhood, particularly in terms of precisely measured fat mass, emphasizing potential health implications for children exposed to PFAS during gestation.

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

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.

Carcinogenicity of perfluorooctanoic acid and perfluorooctanesulfonic acid

30 Nov 2023 | Lancet Onc.

A Working Group of 30 scientists from 11 countries met at the International Agency for Research on Cancer in Lyon, France, to finalise their evaluation of the carcinogenicity of two agents: PFOA and PFOS, including their corresponding isomers and salts.

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

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.

Comparison of Serum PFAS Concentrations in Incumbent and Recruit Firefighters and Longitudinal Assessment in Recruits

28 Nov 2023 | J Occup Environ Med

Incumbent firefighters had lower n-PFOA and PFNA than recruits and most PFAS significantly decreased over time among male recruits, suggesting that firefighting activities may not increase PFAS exposure.

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

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

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.
