title: Developmental toxicity of dimethylformamide in the rat following inhalation exposure.
abstract: Dimethylformamide (DMF) is a widely used industrial solvent. DMF has been reported to be a developmental toxin when given to rodents by injection or following dermal administration. In this study, groups of pregnant rats were exposed by inhalation to either 0 (control), 30, or 300 ppm DMF from gestation day 6 through 15. In the 300 ppm rats, both maternal weight gain during gestation and fetal weights were lower than those of the controls. Fetal resorptions were not increased in this group. No significant differences among either maternal or fetal rats were seen in the 30 ppm group compared to controls. Both fetal and maternal toxicity were noted at 300 ppm and the no observed effect level under these experimental conditions was 30 ppm for both the dams and the conceptuses. DMF did not produce malformations in the rat fetus even at a level that was toxic to the dam.
