Any other information on results incl. tables

No rats died on the study.

Dyspnea was observed during the exposure and continued post-exposure (up to 5 days) in a few animals. Mean body weight gain was normal 14 days after exposure. At necropsy, red foci in the lungs of a few rats were observed.

Applicant's summary and conclusion

Interpretation of results:
practically nontoxic
Remarks:
Migrated information Criteria used for interpretation of results: expert judgment
Conclusions:
The 1 hr LC50 was > 203 mg/L.
Executive summary:

One group of 5 male and 5 female albino rats was exposed to EBTBP at a concentration of 203 mg/L for 1 hour. Dyspnea and nasal discharge were the principal signs observed during the exposure. No deaths occurred during treatment or the during the 14 day observation period. The inhalation LC50 was > 203 mg/L for 1 hour. This study was performed according to Good Laboratory Practices.
