- Executive summary:
An acute inhalation toxicity test was conducted with rats to determine the potential for test substance to produce toxicity from a single exposure via the inhalation (nose-only exposure) route according to the guidelines OECD 403 and EPA OPPTS 870.1300.
After establishing the desired generation procedures during pre-test trials, 10 healthy Sprague-Dawley derived, albino rats (5/sex) were exposed to the test atmosphere for 4 hours. Chamber concentration and particle size distributions of the test substance were determined periodically during the exposure period. The animals were observed for mortality, signs of gross toxicity, and behavioral changes at least once daily for 14 days following exposure. Body weights were recorded prior to exposure and again on Days 1, 3, 7 and 14 (termination). Necropsies were performed on all animals at terminal sacrifice.
All animals survived exposure to the test atmosphere. The gravimetric chamber concentration was 5.18 ± 0.24 mg/L. Based on graphic analysis of the particle size distribution as measured with an Andersen Cascade Impactor, the mass median aerodynamic diameter (MMAD) and geometric standard deviation (GSD) of the 5.18 mg/L atmosphere was 3.0 μm ± 2.15 (MMAD ± GSD).
Immediately following exposure and throughout the 14-day observation period, all animals appeared active and healthy. There were no clinical signs of toxicity or abnormal behavior observed in this study. Although all rats lost body weight one day following exposure, all animals gained weight over the entire observation period. No gross abnormalities were noted for any of the animals when necropsied at the conclusion of the 14-day recovery period.
Under the conditions of this study, the single 4-hour inhalation medial lethal concentration (LC50) for the test substance is greater than 5.18 mg/L in male and female rats.
