Implication

Controlled exposure study demonstrates dose-dependent respiratory tract injury and organ changes in hamsters, indicating a no-toxic-effect threshold at 390 ppm.

Key Points

To evaluate the subacute inhalation toxicity and respiratory pathology caused by repeated exposure to varying concentrations of acetaldehyde vapor.
Exposed four groups of 20 hamsters each to acetaldehyde vapor concentrations of 0, 390, 1,340, or 4,560 ppm.
Administered vapor for six hours per day, five days per week, across a 90-day period.
Exposure to 4,560 ppm caused growth retardation, ocular and nasal irritation, increased erythrocyte counts, elevated heart and kidney weights, and severe necrosis, inflammation, hyperplasia, and metaplasia predominantly in the upper respiratory tract.
Exposure to 1,340 ppm resulted in increased kidney weights in males and slight hyperplastic and metaplastic alterations of the tracheal epithelium.
Exposure to 390 ppm produced no detectable treatment-related changes, defining the no-toxic-effect level.
