Summary of benzene low-dose risk assessments.
d Pregnant Sprague-Dawley rats from the twelfth day of pregnancy at a concentration of 200 ppm, 4
hours/day, 5 days/week to delivery, then offspring assumed to be exposed to 200-300 ppm 4-7
hours/day, 5 days/week for 104 weeks. Exposure in utero not calculated for total lifetime dosage.
e Provided for comparative purposes.
f Estimated lifetime dosage by the U.S. EPA-CAG (US EPA, 1979)
