Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
No mortality occured in the test. All animals survived to an exposure of 8 h to saturated vapor of quinoline.
Executive summary:

The acute inhalation toxicity has been determined in rats using the maximum time for no death upon exposure to saturated vapor.

All animals survived to the exposure of 8h.
