- Conclusions:
- Single application of the limit dose of 10000 mg test item per kg bw did not cause lethality in female rats during the 14 days observation period, resulting in a LD50 > 10000 mg/kg bw.
- Executive summary:
Female Wistar rats were subjected to test acute oral toxicity. The test item was administered at the limit dose of 10000 mg/kg bw to ten rats. During the 14 days observation period no animals died and there were no changes found in necropsy, thus leading to a median lethal dose (LD50) > 10000 mg/kg bw.
Therefore, the test item has not to be classified for acute oral toxicity according to Regulation (EC) No 1272/2008.

- GENERATION OF TEST ATMOSPHERE / CHAMBER DESCRIPTION
- System of generating particulates: Dust atmosphere of the test item was generated with a vertical two-stage glass generator consisting of a dust reservoir and a cyclone elutriator. An electric steel motor and steel rod with plastic paddles agitated dust in the generator. Air introduced at the reservoir carried dust particles upward to the elutriator. Additional houseline air carried airborne dust into the chamber.
TEST ATMOSPHERE
- Brief description of analytical method used: Samples from chamber were analyzed at 30-minute intervals. Calibrated volumes of test atmosphere were passed through preweighed glass fiber filters (Gelman Type AE, 25 mm) and atmospheric concentrations determined from filter weight gain. Airborne particle size measurements were obtained using Sierra 8-stage cascade impactor.
TEST ATMOSPHERE (if not tabulated)
- Particle size distribution:
at concentration of 3.1 mg/L: 21 % have an aerodynamic diameter < 13 µm
at concentration of 2.6 mg/L: not determined
at concentration of 2.4 mg/L: not determined
at concentration of 1.6 mg/L: 17 % have an aerodynamic diameter < 13 µm
at concentration of 1.5 mg/L: 12 % have an aerodynamic diameter < 13 µm
- MMAD (Mass median aerodynamic diameter) / GSD (Geometric st. dev.): not calculated
- Analytical verification of test atmosphere concentrations:
- yes
- Remarks:
- gravimetric measurement
- Duration of exposure:
- 4 h
- Concentrations:
- 1.5, 1.6, 2.4, 2.6, 3.1 mg/L
- No. of animals per sex per dose:
- 6
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: daily (already one week before treatment, but the weekends excepted)
- Necropsy of survivors performed: no - Sex:
- male
- Dose descriptor:
- LC50
- Effect level:
- > 3.1 mg/L air (analytical)
- Remarks on result:
- other: no animals died within the 14 day observation period; exposure concentration of 3.1 mg/L corresponds to about 0.65 mg/L respirable dust (21% of dust particles had an aerodynamic diameter < 13 µm)
- Mortality:
- - no deaths occurred
- Clinical signs:
- other: - after exposure all animals had red stained fur
- Body weight:
- - immediately after exposure mild but transient weight loss but resumed a normal weight gain rate two days later
- Gross pathology:
- - not performed
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: other: CLP Regulation
- Conclusions:
- In an acute inhalation toxicity test male rats were exposed to dust concentrations up to 3.1 mg/L test item for 4 hours. Under the conditions tested no animal died during a 14 day observation period, resulting in a LC50 value of > 3.1 mg/L (corresponding to 0.651 mg/L respirable test item).
- Executive summary:
Acute inhalation toxicity of the test item has been investigated in male rats. They were exposed to 3.1 mg test substance per litre for 4 h. The test atmosphere contained only about 21% particles with an aerodynamic diameter (corresponding to 0.651 mg test item of respirable size). All animals survived the 14 day observation period, resulting in a LC50 value of > 3.1 mg/L (corresponding to 0.651 mg/L respirable test item) for the inhalation of dust.
Classification for acute inhalation toxicity is not necessary according to Regulation (EC) No 1272/2008.
