SUBCHRONIC TOXICITY Subchronic Oral Toxicity (28-day, 90-day, or combined with reproductive/developmental) Conclusion: The available subchronic oral toxicity data were judged inadequate to meet the endpoint. Basis for Conclusion: A Japanese 90-day dietary study in mice (Kamata et al. 1989) provides limited relevant information in the English abstract and data tables. The study was not adequate to characterize this endpoint because histopathological analysis was apparently limited to the liver. A fertility study by Wilczynski et al. (1983), discussed under the Reproductive Toxicity endpoint, evaluated male rabbits exposed by oral gavage for 12 weeks, but did not involve treated females. • Repeated Dose 28-Day Oral Toxicity in Rodents (OPPTS Harmonized Guideline 870.3050; OECD Guideline 407) No study of this type was located. 90-Day Oral Toxicity in Rodents (OPPTS Harmonized Guideline 870.3100; OECD Guideline 408) Type: 90-Day repeated oral Species, strain, sex, number: Mouse, Slc/ddY, 12/sex/dose Doses: TDCPP at dietary concentrations of 0, 0.01, 0.04, 0.13, 0.42, and 1.33% in the diet, resulting in reported average daily doses of 0, 13.2, 47.3, 171.0, 576.0, and 1,792.3 mg/kg/day in males and 0, 15.3, 62.5, 213.6, 598.0, and 1,973.1 mg/kg/day in female mice Purity: Not reported Vehicle: None; added to diet Exposure period, frequency: 90 days, ad lib Method: Body weight, food consumption measured weekly. At 1 and 3 months in half the animals, hematologic (erythrocyte, hemoglobin, hematocrit, and leukocyte counts) and clinical chemistry parameters (total protein, albumin, albumin/globulin ratio, blood urea nitrogen, glucose, total cholesterol, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase). At 1 and 3 months, half the animals were necropsied and absolute and relative organ weights were determined for brain, heart, lung, liver, kidney, and spleen. The liver was examined for microscopic histopathology; the English text does not mention whether other tissues were examined. Results: At the highest dietary level, 1.33%, all mice exhibited emaciation, rough hair, and tremor and died within 1 month. At 1.33%, food consumption was reduced and body weight loss occurred in both sexes. Mean body weight gain was reduced by about 10% (estimated from graph) in males at 0.42% throughout the study. The following statistically significant changes 3-10
occurred in treated groups compared to controls. Slight anemia (reduced hemoglobin; p
