Teratogenic potential of triphenyl phosphate in Sprague-Dawley (Spartan) rats.
Male and female Sprague-Dawley (Spartan) rats were fed dietary levels of 0, 0.25, 0.50, 0.75 or 1.00% triphenyl phosphate (TPP) from 4 weeks post weaning for 91 days, through mating and gestation. At these dietary levels, the daily intake of TPP during pregnancy was 0, 166, 341, 516 and 690 mg/kg body weight, respectively. TPP exposure had no toxic effects on mothers or offspring at these dosages. The types of developmental anomalies were similar in both treated and control animals. No significant increases in the incidence of anomalies were seen in the treated groups as compared to control values. TPP was not teratogenic in Sprague-Dawley rats at the levels tested.
