- GENERATION OF TEST ATMOSPHERE / CHAMBER DESCRIPTION
- Exposure apparatus: The test was performed in an apparatus for dynamic spraying of aerosols (manufacturer Joh. Friedrich Bundschuh, Griesheim, Germany). The apparatus consits of a cylinder with several tubes. Through a special nozzle welded with a specific substance-tube the air was pushed via a special filter with a compressor into the cylinder.
- Method of holding animals in test chamber: Tubes connected with the cylinder were configured like restrainer tubes, in the way that only the noses of animals extend into the cylinder.
- Source and rate of air: The air supply was kept constant at 600L/hour with an air-calibrated Rotameter.
- Treatment of exhaust air: At the bottom of the apparatus an exhaust device was installed over which the aerosol was sucked off via cotton and a 10% sodium hydroxide solution for detoxification.
- consumed oxigene replacement: n.a.
- Temperature in closed apparature during exposure (°C): 27°C to 30°C
- humidity, pressure in air chamber: n.a.

Results and discussion
Effect levels
- Sex:
- female
- Dose descriptor:
- LC50
- Effect level:
- ca. 10 600 mg/m³ air
- Based on:
- test mat.
- Remarks:
- analytical
- Exp. duration:
- 4 h
- Mortality:
- Group 1 (3'380 mg/m3): 0/10 animals;
Group 2 (10'328 mg/m3): 3/10 animals; death occured in 3 animals within 156 and 215 minutes after start of treatment
Group 3 (11'080 mg/m3): 9/10 animals; death occured in 8 animals within 105 and 226 minutes after start of treatment and in one rat within day 1 to 2.
Group 4 (11'150 mg/m3): 10/10 animals; death occured in 10 animals within 100 and 173 minutes after start of treatment
Group 5 (27'728 mg/m3): 10/10 animals; death occured in 10 animals within 86 and 211 minutes after start of treatment
Group 6 (58'638 mg/m3): 10/10 animals; death occured in 10 animals within 73 and 158 minutes after start of treatment - Clinical signs:
- other: no detailed information
- Body weight:
- During the 14 day post treatment observation period bodyweight develpment of the survivors was regular.
- Gross pathology:
- Few specific gross pathological changes were recorded for the deceased rats. Lungs were colored dark red to deep black partly with small white areas.
Microscopically an excessive hyperemia of the heart muscle was recorded with no damage of the muscle fiber. At the trachea and the great bronchus-branches there was no indication for damage of the ciliated epithelium. For the examined sections of the lung of all deceased animals hyperemia, distinct lung-edema as well as focal bleeding into the alveolar region was recorded. From the lung results it could not be concluded whether it was a direct effect from the inhaled aerosol or whether it was a sign of terminal heart failure. In conclusion of the pathology report it is mentioned that inhalation of the test item 1,1,1,2,2,3,3,4,4,5,5,6,6-tridecafluoro-8-iodooctane caused death within 226 minutes in all rats that died. Morphological a distinct lung edema was in the foreground. There is no information of effects in survivors mentioned in the report.

Particle size distribution: 95.5 to 99% of particles were determined to be smaller than 5 µm.
Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based on the results of a 4h nose-only study in female rats the LC50 was determined to be 10'600 mg/m3 (10'100 – 10'800 mg/m3).
- Executive summary:
A sufficiently reported acute inhalation toxicity study with reliability of 2 is available with the test substance. The study was performed prior to implementation of GLP. In order to determine the acute inhalation potential of the test item 1,1,1,2,2,3,3,4,4,5,5,6,6-tridecafluoro-8-iodooctane (purity 97%) 10 female rats per dose group were exposed to the test substance by nose-only inhalation for 4 hours. The aerosol concentration in air was measured to be 3'380, 10'328, 11'080, 10'150, 27'728 and 58'638 mg/m3, respectively. The particle size distribution was determined to be 95.5% to 99% smaller than 5 µm. Based on the results of this study the LC50 was determined to be 10'600 mg/m3 (10'100 – 10'800 mg/m3).
