Administration / exposure
- Route of administration:
- inhalation: aerosol
- Type of inhalation exposure:
- nose only
- Vehicle:
- air
- Mass median aerodynamic diameter (MMAD):
- > 1 - < 4 µm
- Geometric standard deviation (GSD):
- > 1.5 - < 3
- Details on inhalation exposure:
- Inhalation exposure was performed using a flow-past, nose-only exposure system. The animals were confined separately in restraint tubes which were positioned radially around the exposure chamber. The exposure system ensured a uniform distribution and provided a constant flow of test material to each exposure tube. The flow of air at each tube was approximately 1 L/min, which was sufficient to minimize re-breathing of the test aerosol as it is more than twice the respiratory minute volume of rats.
Exposure chambers type EC-FPC-232 (anodised aluminium, volume inside compartment: approximately 3 L), equipped with glass exposure tubes were used. The rats were individually exposed in glass tubes matching their size. Before treatment start the homogeneity for the different levels of the exposure chamber was confirmed. Cross and longitudinal sections of the chamber are shown in Figure 1.
The temperature and relative humidity of the test atmosphere in the exposure chamber was maintained as required by experimental conditions. Air flow was monitored regularly. - Analytical verification of test atmosphere concentrations:
- yes
- Remarks:
- gravimetric
- Duration of exposure:
- 4 h
- Concentrations:
- 5.16 mg/l
- No. of animals per sex per dose:
- 3 males, 3 females
- Control animals:
- no
- Details on study design:
- The test was based on a stepwise procedure. The starting dose (5 mg/L air, during 4 hours) was selected since the test item was expected to be non-toxic according to previous studies conducted by sponsor. No additional doses were required.
3 male and 3 female rats in group A (starting dose group) were exposed for 4 consecutive hours.
During an observation period of 14 days, clinical observations and body weight were collected in order to characterise the toxicological effects of the aerosol. All animals were subjected to a gross necropsy and descriptions of all macroscopic abnormalities were recorded.
Acclimatisation to the nose-only restraining tubes was performed for approximately 80 minutes immediately before the exposure. - Statistics:
- No statistical analysis was performed.
Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LC50
- Effect level:
- > 5.16 mg/L air
- Based on:
- test mat.
- Exp. duration:
- 4 h
- Mortality:
- none
- Clinical signs:
- other: Dirty fur, chromorrhinorrhea, chromodacryorrhea and piloerection were observed in all animals immediately after administration and 1 hour after exposure. These clinical signs were not longer present on day 2 of study and no other clinical signs were obser
- Body weight:
- A slight decrease in body weight (approximately 1-2% less than body weight at pre-treatment) was observed in all animals from day 1 of study to day 2 of study. Males recovered the body weight at pre-treatment at day 3 of study. Thereafter, a normal body weight gain was observed in males. By contrast, a stagnation of body weight was observed in females, which did not recover the body weight at pre-treatment until day 6 of study. Females gained weight normally from day of study 6 onwards.
- Gross pathology:
- No macroscopic findings were observed during necropsy.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- No classification according to (EU) No. 1272/2008 required.
- Executive summary:
Treatment of Sprague Dawley rats with the test item resulted in no deaths. Clinical signs were considered to be mainly stress related to the nose-only exposure but a contribution of the treatment with the test item cannot be completely excluded. Additionally, body weight stagnation in females is considered to be related with the test item.
It is concluded that, under the experimental conditions:
- LC50 of the test item was greater than 5.16 mg/L air (gravimetric aerosol concentration)
- Based on the GHS classification criteria, the test item can be considered as not classified.
