Test animals
- Species:
- rat
- Strain:
- other: Sprague-Dawley and CFE rats
- Sex:
- male
Administration / exposure
- Route of administration:
- inhalation: vapour
- Type of inhalation exposure:
- whole body
- Vehicle:
- other: air
- Details on inhalation exposure:
- m-nitrotoluene was tested at a saturated vapour concentration. Production of essentially saturated vapours of the m-nitrotoluene was accomplished by bubbling dry air through a fritted disc immersed in the sample. The resultant vapours were then passed through a 9-liter glass chamber containing the experimental animals.
All exposures were continuously analyzed using a Beckman Model 400 total hydrocarbon analyzer. - Analytical verification of test atmosphere concentrations:
- no
- Duration of exposure:
- 4 h
- Concentrations:
- 157 ppm (77% saturation) = 880 mg/m³
- No. of animals per sex per dose:
- 10
- Control animals:
- other: not applicable
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: All animals were observed for sings of toxicity and mortality during exposure and for the 4-days immediately following exposure. Animals were weighed immediately prior to exposure and again at 14 days postexposure on survivors
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight, grosspathology - Statistics:
- Determination of the LC50 was made by probit method (Finney, 1952, Probit Analysis, 2nd Edition, King Review Press)
Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LC50
- Effect level:
- > 880 mg/m³ air
- Exp. duration:
- 4 h
- Body weight:

Any other information on results incl. tables
No death occurred during exposure or during the subsequent 14-d observation period. Gross pathologic examination of rats sacrificed after 14 days revealed no leasions which could be attributed to exposure (no further information given.)
Applicant's summary and conclusion
- Executive summary:
Kinkead ER (1977):
10 rats were exposed to an atmosphere essentially saturated with 3-nitrotoluene for four hours (rat: 157 ppm = 880 mg/m³) according to a method similar to OECD guideline 403 with deviations (Analytical purity not reported. Animal housing conditions not reported. Only one dose concentration tested). All animals were observed for signs of toxicity and mortality during exposure and for the 14-days immediately following exposure. Animals were weighed immediately prior to exposure and again at 14 days postexposure on survivors.
Determination of the LC50 was made by probit method (Finney, 1952, Probit Analysis, 2nd Edition, King Review Press).
No death occurred during exposure or during the subsequent 14 day post exposure observation period. No lesions attributable to exposure could be discovered during gross pathological evaluation, neither in rats nor in mice.
LC50 was estimated to be greater than 880 mg/m³.
