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.
