Drs. Pollack and Brouwer at the University of North Carolina determined the relationship between methanol exposure and its uptake into and elimination from the blood of nonpregnant and pregnant rodents. The investigators exposed rats and mice at several different stages of gestation to methanol intravenously or orally (doses ranged from 100 mg/kg of body weight to 2,500 mg/kg) or by inhalation (1,000 to 20,000 ppm for 8 hours). They measured blood, urine, and amniotic fluid concentrations of methanol and used the data to develop a model of methanol distribution in rodents.
