The concentration of the tested substance diminishing the repiratory frequency to 50% (RD50) was 3980 mg/m3.
Applicant's summary and conclusion
- Conclusions:
- Methyl-5-heptan-3-one diminished the respiratory rate of mice .
- Executive summary:
Respiratory irritation to 5-methylheptan-3-one was tested by measuring the change in the breathing frequency of mice in the presence of the tested substance to indicate a sensory irritation to the upper repiratory tract. 6 mice were restrained in body plethysmographs to measure the respiratory rate while the head of the mouse was extended into a 200-Liter inhalation chamber maintained which contained the tested substance at the required concentration. 4 exposure concentrations of 5-methylheptan-3-one were tested. From the data obtained, a concentration-effect curve was extrapolated and fitted. From the equation, the concentration of the tested substance diminishing the repiratory frequency to 50% was calculated to be 3980 mg/m3. The results confirms the classification of the test substance 5-methylheptan-3-one in the Annex VI of the Regulation (EC) 1272/2008 as respiratory irritating (STOT SE 3, H335).
