The acute inhalation toxicity of hydrogen peroxide (50 %) aerosols was tested in male and female Sprague-Dawley rats according to US EPA Guideline Vol 50 (§798.1150). Animals received a single 4 -hour whole-body exposure to the maximum attainable aerosol concentration of 170 mg/m3. All tested animals survived the exposure and subsequent 14 -day post-exposure observation period. Signs of treatment were minimal during the exposure but a few responses such as nasal discharge were noted during the whole 14 -day observation period. A minimal, transient adverse effect upon body weight was produced by treatment. Otherwise, body weight gain was considered unremarkable. Gross post mortem observations and lung weights were considered unremarkable. No LD50 value for acute inhalation toxicity could be established and the LD50 value must be greater than the attainable aerosol concentration of hydrogen peroxide of 170 mg/m3.
