Short-term vapor inhalation toxicity was studied in rats with a constant
flow pump for 3 wks, 5 d/w, 6 h/d. At 250 ppm (1608 mg/m³), nose and eye
irritation and labored breathing were observed. The body weight gain was
slow. There were no changes in the hematological parameters. No
pathological (macroscopical and microscopical) effects on organs were
observed. At 100 ppm (643 mg/m³), no toxic effects were observed.
Conclusion: The NOAEC for repeated inhalation toxicity is considered to
be 100 ppm (643 mg/m³).
