Type of information:

Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Guideline 403 (Acute Inhalation Toxicity)
Principles of method if other than guideline:
The test was performed in principle as described in OECD test guideline 403. It demonstrates the toxicity of an atmosphere saturated with vapors of the volatile components of a test substance at 20°C. Young adult laboratory rats, 6 per sex, were exposed sequentially to the vapors generated by bubbling 200 L/h air through a substance column of about 5 cm above a fritted glass disc in a glass cylinder for 8 h. The exposure was subsequently repeated in the same manner. No analytical determination of the atmosphere concentrations was performed. The nominal concentration was calculated as quotient of the amount of test substance weight loss during exposure, and the amount of air used during exposure. Group-wise documentation of clinical signs was performed over a 7 day study period. Body weight of groups was determined before the start of the study and at the end of the observation period.

TEST ATMOSPHERE
- Brief description of analytical method used: no analytics performed
- Samples taken from breathing zone: no
Analytical verification of test atmosphere concentrations:
no
Duration of exposure:
8 h
Concentrations:
No verification of the concentration was performed. Nominal concentration: 0.3 mg/l (determined by means of re-weighing)
No. of animals per sex per dose:
6
Control animals:
no
Details on study design:

Based on:
test mat.
Exp. duration:
8 h
Remarks on result:
other: IRT: the calculated nominal test atmosphere has to be considered as saturated at 20°C
Mortality:
There was no mortality after 8 h exposure of a saturated atmosphere.
Clinical signs:
other: No clinical findings were noted.
Body weight:
No data
Gross pathology:
No gross pathological findings were noted.
Interpretation of results:
GHS criteria not met
