Both chemicals have caused tumors in animal studies. The most consistent findings from human epidemiology studies are increased cholesterol levels among the toxicity assessment for perfluorobutane sulfonic acid (PFBS) and its potassium salt, potassium perfluorobutane sulfonate (K+PFBS), to increase the amount of information the public has on PFAS.

Perfluorochemical PFC Exposure in Children: Associations
The report has been elaborated based on existing expert assessments of for PFOA, PFOS and PFOSA as further in-depth evaluation of the extensive database of original PFOS PFOS has shown moderate acute toxicity by the oral route. The oral LD50 in rats is 230 and 270 mg/kg bw (range 160-340 and 200-370 mg/kg bw) for males and females, respectively. Signs of toxicity included hypoactivity, stained urogenital region, decreased limb tone and ataxia, stomach distension and lung congestion [3, 5]. PFOA 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. While PFOS induced higher toxicity in affecting cytoskeleton signaling, Sertoli cell-cell junction, and inflammation, underlined by Ingenuity pathway analysis. Immunocytochemical staining revealed that PFOS treatment (40 and 80 μM) induced truncated actin filament and disorganized bundled configuration in the cell cytoplasm.
