PFOS and PFOA are weak agonists of PPARα , a causal pathway for induction of hepatocellular carcinoma in rodents. This presentation addresses the question of whether PPARα is involved in the mode-of-action for PFOA and PFOS-induced developmental toxicity and discusses the potential for PFAA to activate PPARα in an in vitro model.

The distinction between PFOS and PFOA, however, may not be easily understood from the above documents. This paper discussed differential toxicity between PFOS and PFOA focusing on neurotoxicity, developmental toxicity and carcinogenicity, mainly based on these documents.

2. 6. PFOS has the potential to cause a range of adverse health effects, including hepatotoxicity, developmental toxicity, neurobehavioral toxicity, immunotoxicity, reproductive toxicity, lung toxicity, hormonal effects and carcinogenicity. Evaluations of PFOS in food have been conducted by the In 1999, EPA ordered companies to examine the effects of perfluorinated chemicals after receiving data on the global distribution and toxicity of PFOS. For these reasons, and EPA pressure, in May 2000, 3M announced the phaseout of the production of PFOA, PFOS, and PFOS-related products—the company's best-selling repellent. Based on toxicity data, the CONTAM Panel of the European Food Safety Agency (EFSA) for human exposure to PFOS and PFOA has calculated a maximum tolerable daily intake (Tolerable Daily Intake, TDI) of 150 ng / kg per day, respectively 1.5 µg / kg per day.In addition, the EFSA notes that health effects to the public are not very likely, but that monitoring over time is certainly recommended.

PFOS may increase the risk of liver damage, thyroid dysfunction and heart disease. PFOS affects antibody production and compromises the body’s overall immunity. PFOS exposure may result in low birth weight, accelerated puberty and skeletal variations. PFOS is particularly detrimental to the thyroid glands, liver and heart health. The distinction between PFOS and PFOA, however, may not be easily understood from the above documents. This paper discussed differential toxicity between PFOS and PFOA focusing on neurotoxicity, developmental toxicity and carcinogenicity, mainly based on these documents.

A/ Bioackumulation av PFOS i sedimentlevande organismer med In order to investigate the toxicity of PFOS, the deposit-feeding amphipod M. affinis was.

Environmental Science & Technology 2018, 52 (21) , … 2019-11-30 Overall, the toxicity studies available for PFOS demonstrate that the developing fetus is particularly sensitive to PFOS induced toxicity. Human epidemiology data report associations between PFOS exposure and high cholesterol, thyroid disease, immune suppression, and some reproductive and developmental parameters, including 2021-04-08 2020-09-29 Used the ratio of PFOS toxicity values between marine and freshwater as a surrogate for the ratio of PFOA toxicity values between marine and freshwater. This method is based on the data-bridging approach for aquatic toxicity (USEPA, 2010). • Public Health Goal Initiation Webinar PFOA and PFOS Toxicity and Epidemiology Data Agenda Nov 5, 2019 Lauren Zeise Introduction and Welcome Nov 15, 2019 Chris Banks and Anatoly Soshilov Presentation Nov 15, 2019 Chad Blystone Presentation Nov 15, 2019 Ron A.
