Toxic effects of PFOS/PFOA and their internal exposure in Chinese general population

open access: yesZhongguo shipin weisheng zazhi, 2022
As widely used synthetic chemicals, perfluorooctane sulfonic acid (PFOS) and perfluorooctanic acid (PFOA) are ubiquitous in the environment and the human body.

Serum Levels of Perfluorooctanoic Acid and Perfluorooctane Sulfonate and Pregnancy Outcome [PDF]

open access: yesAmerican Journal of Epidemiology, 2009
The authors examined the association of serum perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) with self-reported pregnancy outcome in Mid-Ohio Valley residents (2000-2006) highly exposed to PFOA. Data on 1,845 pregnancies within the 5 years preceding exposure measurement were analyzed for PFOA, and data on 5,262 pregnancies were ...

Effects of perfluorooctane sulfonate and perfluorooctanoic acid on the zooplanktonic community

open access: yesEcotoxicology and Environmental Safety, 2004
This comparative survey summarizes six individual studies on the ecological effects of two common perfluorinated surfactants, PFOS and PFOA, on zooplankton. We compare the test designs and quantify the relative sensitivity and statistical power (1-beta > or = 0.8).

Perfluorooctane sulfonic acid, a persistent organic pollutant, inhibits iodide accumulation by thyroid follicular cells in vitro [PDF]

open access: yes, 2020
Poly- and perfluoroalkyl substances (PFAS) are a class of endocrine disrupting chemicals (EDCs) reported to alter thyroid function. Iodide uptake by thyroid follicular cells, an early step in the synthesis of thyroid hormones, is a potential target for ...

Sorption of perfluorooctanoic acid, perfluorooctane sulfonate and perfluoroheptanoic acid on granular activated carbon [PDF]

open access: yesChemosphere, 2016
The sorption of perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), and perfluoroheptanoic acid (PFHpA) on granular activated carbon (GAC) was characterized and compared to explore the underlying mechanisms. Sorption of the three perfluoroalkyl acids (PFAAs) on GAC appeared to be a rapid intra-particle diffusion process, which were well ...

Breast cancer risk and serum levels of per- and poly-fluoroalkyl substances: a case-control study nested in the California Teachers Study

open access: yesEnvironmental Health, 2018
Background Per- and poly- fluoroalkyl substances (PFASs) are a large family of synthetic chemicals, some of which are mammary toxicants and endocrine disruptors. Their potential as breast carcinogens is unclear.
