The toxicology of perfluorooctanoate

Authors: Kennedy, GL; Jr; Butenhoff, JL; Olsen, GW; Connor, JCO; Seacat, AM; Perkins, RG; Biegel, LB; Murphy, , SR; Farrar, DG (2004) Critical Reviews in Toxicology 34:351-384. [Review] HERO ID: 724950

[More] PFOA is a peroxisome proliferator (PPAR agonist) and exerts morphological and biochemical effects characteristic of PPAR agonists. These effects include increased beta-oxidation of fatty acids, increases in several cytochrome P-450 (CYP450)-mediated reactions, and inhibition of the secretion of very low-density lipoproteins and cholesterol from the liver. These effects on lipid metabolism and transport result in a reduction of cholesterol and triglycerides in serum and an accumulation of lipids in the liver. The triad of tumors observed (liver, Leydig cell, and pancreatic acinar-cell) is typical of many PPAR agonists and is believed to involve nongenotoxic mechanisms. The hepatocellular tumors observed in rats are likely to have been the result of the activation of the peroxisome proliferator activated receptor alpha (PPARalpha). The tumors observed in the testis (Leydig-cell) have been hypothesized to be associated with an increased level of serum estradiol in concert with testicular growth factors. The mechanism responsible for the acinar-cell tumors of the pancreas in rats remains the subject of active investigation. The mechanism resulting in the hepatocellular tumors in rats (PPARalpha activation) is not likely to be relevant to humans. Similarly, the proposed mechanism for Leydig-cell tumor formation is of questionable relevance to humans. Acinar tumors of the pancreas are rare in humans, and the relevance of the these tumors, as found in rats, to humans is uncertain. Epidemiological investigations and medical surveillance of occupationally exposed workers have not found consistent associations between PFOA exposure and adverse health effects

Acute inhalation toxicity of ammonium perfluorononanoate

[More] Ammonium perfluorononanoate (CAS Registry No. 4149-60-4) is a white powder that can become airborne. Its acute inhalation toxicity in male rats was studied. Male rats were exposed for single 4-hr periods to dust concentrations ranging from 67 to 4600 mg/m3. The LC50 was determined to be 820 mg/m3, with the lowest concentration causing death being 590 mg/m3. Ammonium perfluorononanoate was classified as moderately toxic by the acute inhalation route. Exposure to ammonium perfluorononanoate caused a pronounced increase in liver size. The acute toxicity of ammonium perfluorononanoate appears to be similar to that of its 8-carbon homologue, ammonium perfluorooctanoate, but considerably less than that of the 10-carbon homologue, perfluoro-n-decanoic acid.

Inhalation toxicity of ammonium perfluorooctanoate

[More] Ammonium perfluorooctanoate (CAS Registry No. 3825-26-1) is a fine white powder which can become airborne; hence its inhalation toxicity was studied in the male rat. The compound was found to be moderately toxic following single 4-hr exposures, with an LC50 of 980 mg/m3. This concentration produced both an increase in liver size and corneal opacity. Both findings diminished with increasing time after exposure. Subchronic head-only inhalation exposures (6 hr/day on 5 days/wk for 2 wk to 0, 1, 8 or 84 mg/m3) suppressed body-weight gain at 84 mg/m3. Reversible liver-weight increases, reversible increases in serum enzyme activities, and microscopic liver pathology, including necrosis, occurred at exposure of 8 and 84 mg/m3. No ocular changes were produced. Concentrations of organofluoride in the blood showed a dose relationship with initial levels of 108 ppm in rats treated at 84 mg/m3 falling to 0.84 ppm after 84 days with a blood half-life of 5-7 days. The no-observed-effect level was 1 mg/m3 and a mean organofluoride blood level of 13 ppm was detected in rats immediately after the tenth exposure to an atmospheric level of 1 mg ammonium perfluorooctanoate/m3.

Dermal toxicity of ammonium perfluorooctanoate

[More] Ammonium perfluorooctanoate (CAS Registry No. 3825-26-2) is used commercially in the aqueous polymerization of fluorinated monomers. Because the chemical exists as a fine white powder which can come in contact with skin, its dermal toxicology was studied in rabbits and rats. Dermal applications of 0.5 g for 24 hr produced mild irritation to rabbit skin. The dermal LD50 was 4300 mg/kg for rabbits, 7000 mg/kg for male rats, and greater than 7500 mg/kg for female rats. Rat skin showed less irritation than rabbit skin and the general effects were more pronounced for the male (compared to the female) rat. Subchronic dermal treatment (10 applications, 5 doses, 2 rest days, 5 doses) with either 0, 20, 200, or 2000 mg/kg resulted in no, no, mild, or marked decreases in body weights, respectively. Increases in serum enzyme activities indicating hepatic effects occurred in treated rats. Liver weights were increased and necrosis and enlargement of hepatocytes were microscopically observed. Rats in the 2000-mg/kg-dose group also had epidermal necrosis at the application site. Blood organofluorine amounts were increased in a dose-related manner. All of the treatment-related toxicity findings resolved during a 42-day recovery period although prior exposure was evident by the presence of organofluorine in the blood.

[More] Ammonium perfluorooctanoate (APFO, greater than 95% pure) was administered to Sprague-Dawley rats from Days 6 through 15 of gestation by inhalation as a dust (whole body exposure) for 6 hr/day at 0, 0.1, 1, 10, and 25 mg/m3, or by gavage at 100 mg/kg body wt/day in corn oil. Maternal deaths occurred in the groups given the highest level of APFO by each route and overt toxicity was evident among the surviving dams of these groups and among those of the 10-mg/m3 group. The fetuses were examined for external, visceral, and skeletal alterations and for APFO-related macroscopic and microscopic alterations of the eyes. In the postpartum period, pups from additional control and experimental dams were examined externally and ophthalmoscopically, and the usual fertility and viability indices were calculated. A teratogenic response was not demonstrated. Toxic effects on the conceptus were noted only in the groups given the highest level of APFO by each route. Hence, APFO was not demonstrated to represent a unique hazard to the conceptus of the rat.
