(4) Other Studies Relevant to Material: Triethylene Glycol was given to rats by inclusion in the diet for 90 days at concentrations of 10,000, 20,000, or 50,000 ppm. At the highest dose, there were decreases in body weight. Physiologic responses to these high doses were observed in kidney weight and urinalysis. No specific organ toxicity was seen. (3) In a 9-day (whole body) repeated exposure (6 h/day) study with rats, mortality occurred at 4,284 mg/M3 and effects included eye irritation and increased alanine aminotransferase and alkaline phosphatase activities; at 494 mg/M3, there was slightly increased alkaline phosphatase activity. (3) In a subsequent 9-day (nose-only) repeated aerosol study, rats were exposed to concentrations up to 1,036 mg/M3. The only effect noted was slight (not statistically or biologically significant) decrease in body weight gain at 517 mg/M3 and 1,036 mg/M3, but not at 102 mg/M3. No indications of local or systemic target organ toxicity were noted, including effects on hematology, clinical chemistry or urinalysis. (3) In a sensory irritation study in mice, exposure to high concentrations of Triethylene Glycol aerosol resulted in decreased respiratory rate. The RD50, or concentration that produced a 50% decrease in respiratory rate, was 5.1 mg/L. (3) There was no evidence in developmental toxicity studies for either embryotoxic or teratogenic effects in mice or rats given Triethylene Glycol by gavage. Maternal toxicity was seen as reduced body weight and food consumption, increased water consumption and increased relative kidney weight with rats, and clinical signs and increased relative kidney weight with mice. (3) There was no histologic evidence of damage to the kidneys in either species. The no-observable effects dose for maternal toxicity were 1,125 mg/Kg/day for rats and 5,630 mg/Kg/day for mice. Minor fetotoxicity (reduced fetal body weights and increased skeletal variations) was resent with doses of 11,260 mg/Kg/day for rats, 5,620 and 11,260 mg/Kg/day for mice. The no-observable effect dose for fetotoxicity was 5,630 mg/Kg/Day for rats and 563 mg/Kg/day for mice.
