Abstract
Dosages of propargyl alcohol ranging from 0 to 400 mg/kg in 0.5 ml aqueous solutions were administered by gavage to young adult male and female rats of the Sprague‐Dawley strain weighing from 180 to 200 g. The treated animals were held 48 hrs at 24°C with food and water ad libitum, after which the dead rats were counted. The oral LD50 was calculated by the probit method (Finney, 1971) as 110 (100–120) mg/kg for male rats and 55 (50–60) mg/kg for female rats.
