Test animals

Species:
rat
Strain:
not specified
Sex:

Administration / exposure

Route of administration:
inhalation: vapour
Type of inhalation exposure:
whole body
Vehicle:
other: unchanged (no vehicle)
Details on inhalation exposure:
GENERATION OF TEST ATMOSPHERE / CHAMBER DESCRIPTION
- A saturated atmosphere was generated by bubbling 200 l/h air at 20 ° C through a substance column of about 5 cm above a fritted glass disc in a glass cylinder for 8 hours.

TEST ATMOSPHERE
- No analytical determination of the atmosphere concentration was performed. The nominal concentration was calculated as the quotient of the amount of test substance weight loss during the exposure and the amount of air used during the exposure.
Analytical verification of test atmosphere concentrations:
no
Duration of exposure:
8 h
Concentrations:
saturated atmosphere
No. of animals per sex per dose:
6 males, 6 females
Control animals:
no
Details on study design:
- Duration of observation period following administration: 2 days
- Observations: on day 0 and day1
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs and body weight

Any other information on results incl. tables

mean substance concentration (calculated):

1.39 g/1600 l air = 0.87 mg/l air (on day 02.02.1977) (3 males and 3 females used)

1.44 g/1600 l air = 0.90 mg/l air (on day 03.02.1977) (3 males and 3 females used)

overall mean: 0.885 mg/l air
