Transfer of perfluorooctane sulfonic acid (PFOS) from contaminated feed to dairy milk

, 2013
Dietary intake is the predominant route for human exposure to perfluorooctane sulfonic acid (PFOS). Single pollution events may thus affect human exposure if polluted ground and water is used to produce animal feed or food.

Issues raised by the reference doses for perfluorooctane sulfonate and perfluorooctanoic acid

Environment International, 2017
On 25th May 2016, the U.S. EPA released reference doses (RfDs) for Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA) of 20ng/kg/day, which were much more conservative than previous values. These RfDs rely on the choices of animal point of departure (PoD) and the toxicokinetics (TK) model.

Toxicity of perfluorooctane sulfonate and perfluorooctanoic acid to plants and aquatic invertebrates [PDF]

Environmental Toxicology, 2008
Abstract Acute toxicities of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) were tested on four freshwater species and three plant species. PFOS was more toxic than PFOA for all species tested in this study.

Occurrence of Perfluorooctanoic Acid and Perfluorooctane Sulfonate in Milk and Yogurt and Their Risk Assessment [PDF]

International Journal of Environmental Research and Public Health, 2016
Although perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) have been identified in milk and dairy products in many regions, knowledge on their occurrence in Xinjiang (China) is rare. This study was conducted to measure the levels of PFOA and PFOS in milk and yogurt from Xinjiang and to investigate the average daily intake (ADI) of ...

Multistressor Interaction of Perfluorooctane Sulfonate (PFOS) and Temperature in Two Estuarine Fish Species, Red Drum ( Sciaenops ocellatus ) and Sheepshead Minnow ( Cyprinodon variegatus )

Environmental Toxicology, Volume 41, Issue 11, Page 1167-1178, November 2026.
ABSTRACT Perfluorooctane sulfonate (PFOS), a perfluoroalkyl substance (PFAS), is characterized by a long, fluorinated carbon chain which makes it ideal for oil‐ and water‐repellent products but detrimental for the environment, where it persists and accumulates in organisms.

Toxicity of perfluorononanoic acid and perfluorooctane sulfonate to Daphnia magna

Water Science and Engineering, 2015
AbstractIn order to study toxicological effects of perfluorononanoic acid (PFNA), perfluorooctane sulfonate (PFOS), and their mixtures (PFNA/PFOS) on Daphnia magna (D. magna), a suite of comprehensive toxicity tests were conducted, including a 48-h acute toxicity test, a 21-day chronic test, a feeding experiment, and a biomarker assay.

Associations of Serum Per‐ and Polyfluoroalkyl Substances (PFAS) With Epigenetic Age and DNA Methylation in US Airport Firefighters

Environmental and Molecular Mutagenesis, Volume 67, Issue 8-9, October-November 2026.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS) are synthetic chemicals used in a variety of consumer and industrial applications for their water‐ and oil‐resistant properties. Firefighters can be exposed to PFAS as part of their job through gear, aqueous film‐forming foams (AFFFs) used to extinguish aircraft and liquid fuel fires, along with ...

Ecotoxicological Insights From Ex Vivo Exposure of Whole Blood to PFOS and Glyphosate: Oxidative Stress and Immune Disruption

Environmental Toxicology, Volume 41, Issue 10, Page 1097-1104, October 2026.
ABSTRACT This study investigated the immunomodulatory effects of PFOS and glyphosate (GLY), both individually and in combination, on the whole blood of three ruminant species (cow, goats, and sheep) exposed ex vivo to environmentally relevant concentrations. The research focused on key biomarkers of oxidative stress (MDA), inflammation (myeloperoxidase

An assessment of PFAS contamination in wild boar meat and liver

Environmental Sciences Europe
In this study 266 wild boar samples (152 meat and 114 liver) from Germany were evaluated for contamination with four EU-regulated perfluoroalkyl substances (PFAS), namely perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA ...
