Test animals
- Species:
- rat
- Strain:
- Wistar
- Sex:
- male/female
Administration / exposure
- Route of administration:
- inhalation: aerosol
- Type of inhalation exposure:
- nose only
- Vehicle:
- clean air
- Mass median aerodynamic diameter (MMAD):
- >= 2.7 - <= 2.8 µm
- Geometric standard deviation (GSD):
- >= 2.33 - <= 2.58
- Analytical verification of test atmosphere concentrations:
- yes
- Duration of exposure:
- 4 h
- Concentrations:
- targeted: 5 mg/l, achieved: 5.35 mg/l
- No. of animals per sex per dose:
- 1 male and 1 female for the sighting study, 5 male animals for the main study
- Control animals:
- no
Results and discussion
- Preliminary study:
- In 1 male and 1 female absence of mortality or toxicity at a target exposure level of 5 mg/L
Effect levels
- Key result
- Sex:
- male
- Dose descriptor:
- LC0
- Effect level:
- 5.35 mg/L air
- Based on:
- test mat.
- Mortality:
- No mortality was observed.
- Clinical signs:
- salivation
- Body weight:
- On the day following exposure (Day 2), body weight loss was evident in 4/5 males exposed to 5.35 mg/L. The group mean body weight was comparable to Day 1 values by the next weighing occasion (Day 7) and continued to increase for the remainder of the observation period.
The changes in body weight gain on Day 2 are considered to be a consequence of the exposure (duration and removal of food and water), and therefore not test item-related. - Gross pathology:
- The macroscopic examination after a single exposure followed by a fourteen day observation period for males exposed to 5.35 mg/L revealed no abnormalities.
Any other information on results incl. tables
Salivation was seen in 2/5 males on return to home cage, resolving by the end of the working day check.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The LC50 (4-hour) is in excess of 5.35 mg/L for male rats.
- Executive summary:
There were no test item-related deaths, macropathology findings or effects on body weight in an acute nose-only inhalation study in rats in accordance with OECD guideline 433. Under the conditions of this study the LC50 (4-hour) is in excess of 5.35 mg/L for male rats.
