They are the Within the group of perfluoroalkylated substances, the perfluoroalkyl acids (PFAAs) and their salts have been the main focal point for regulatory actions until now. The main subgroups are the perfluoroalkyl carboxylic acids and their salts (PFCAs), and the perfluoroalkane sulfonic acids (PFSAs) and their salts. PFC FACT SHEET: PFOS/PFOA TOXICITY OVERVIEW Perfluorooctane Sulfonic Acid (PFOS) and Perfluorooctonoic Acid (PFOA) are members of a group of perfluoroalkyl substances (PFASs) or Perfluorinated Compounds (PFCs) that are manmade, fully-fluorinated compounds.1,2 Both PFOS and PFOA are used in a number of PFOS concentrations in effluents have been reported that approach indicative target values derived from available aquatic toxicity data. PFOA has been found to be weakly carcinogenic. This review shows the importance of the perfluoroalkylated substances for the environment and the necessity to fill the current gaps in knowledge of their environmental fate and effects. Acute toxicities of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) were tested on four freshwater species and three plant species.

Variation i sammansättningen av PFOA/PFOS mellan olika typer av Fish Embryo Toxicity Test (Danio rerio). are compounds of environmental concern due to their toxicity and persistence.

Similar time‐response patterns of PFOS and … OBS has comparable toxicity to PFOS, with 96h-LC 50 values of 25.5 mg/L and 28.4 mg/L for adult zebrafish and tadpoles, respectively (Xu et al., 2017). A 21-day exposure to 300 µg/L OBS caused significant alterations in intestinal microbiota composition and altered 706 metabolites in the liver of adult zebrafish ( Wang et al., 2020 ). Alternative chemicals such as perfluorooctanoic acid (PFOA), or re-formulation of PFOS with shorter carbon chain products have emerged in the commercial market, but at present, little to no information is available concerning the environmental distribution and adverse health effect potentials of these substituting organic fluorochemicals. 2003-04-01 Animal toxicity studies PFOS and PFOA were rapidly absorbed from the gastrointestinal tract of laboratory animals. Both compounds were highly bound to serum albumin and other plasma proteins in the circulation, with the highest concentrations generally reported in liver, serum, lung and kidney.

However, PFOS combined with a HFD exacerbated steatosis in all mice, especially in the hCYP2B6-Tg mice with significant disruption of key lipid metabolism genes such as Srebp1, Pparg, and Hmgcr. In conclusion, CYP2B6 is induced by PFOS but does not alleviate PFOS toxicity presumably due to increased retention.
