Administration / exposure

Route of administration:
inhalation: vapour
Type of inhalation exposure:
not specified
Vehicle:
other: unchanged (no vehicle)
Details on inhalation exposure:
This test was in principle performed as described in OECD Guideline 403.

- Temperature chosen for vapour generation: 20°C.

GENERAL PROCEDURE
Two groups of 3 rats per sex were exposed sequentially to the vapours by bubbling 200l/h air through a substance column of about 5cm above a fritted glass disc in a glass cylinder for different time periods (e.g. 3 min, 10 min, 1 h, 3 h, 7 h or 8 h). The exposure time not causing lethality was usually tested twice.
No analytical determination of the atmosphere concentration was performed. The nominal concentration can be calculated as quotient of the amount of test substance weight loss during the exposure (given in the raw data) and the amount of air used during exposure.
Analytical verification of test atmosphere concentrations:
no
Duration of exposure:
8 h
Concentrations:
saturated vapour
No. of animals per sex per dose:
2 groups of 3 rats/sex; i.e. totally 12 rats
Control animals:
no
Details on study design:
- Duration of observation period following administration: 7-14 days
- Frequency of observations and weighing: Group-wise documentation of clinical signs was performed over the 7-14 day study period. Body weight of groups was determined before start of the study and at the end of the clinical observation period in surviving animals.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight, gross pathology
Statistics:
no data
