title: Four week feeding toxicity study with phenylphosphinic acid in rats.
abstract: Phenylphosphinic acid was fed in graded concentrations of either 0 (control), 100, 1,000, or 10,000 ppm to rats for 28 days. These concentrations provided average daily doses of 8, 76, and 779 mg/kg (males) and 9, 83, and 859 mg/kg (females). No signs of adverse response were detected at any concentration up to the highest levels tested, 10,000 ppm or 779 (male) or 859 (female) mg/kg. Parameters measured were clinical signs, growth, neurobehavior, ophthalmology, and clinical and anatomical pathology. Phenylphosphinic acid is very low in toxicity following 31 days of feeding to the rat.
