Three-month-old male Wistar rats exposed intermittently (5 days weekly, 6 hr/day) to furfuryl alcohol vapor at 1 (25 ppm), 2 (50 ppm), or 4 mumol/liter (100 ppm) for 4 to 16 weeks were lighter than controls at the end of the experiment at the two higher concentration levels. Urinary furoic acid
Groups of F344 rats and B6C3F1 mice were exposed to furfuryl alcohol vapor for 6 hours per day, 5 days per week for 14 days (0, 16, 31, 63, 125, 250 ppm) or 13 weeks (0, 2, 4, 8, 16, 32 ppm). Reduced survival was observed in the 14-day study at 250 ppm. Final mean body weights of rats and mice
