Applicant's summary and conclusion

Interpretation of results:
toxic
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
A secondary source (RTECS) provides limited details of an acute inhalation toxicity study conducted on rats given pinene alpha epoxide (unspecified isomer). The reported LC50 was 3900 mg/m3 (3.9 mg/L).
Executive summary:

A secondary source (RTECS) provides limited coverage of an acute inhalation toxicity study conducted on rats given pinene alpha epoxide (unspecified isomer). [The original Russian publication could not be obtained.] The reported LC50 was 3900 mg/m3 (3.9 mg/L).

According to the EU CLP and DSD regulations, alpha pinene epoxide (unspecified isomer) requires classification as toxic if inhaled and as harmful by inhalation, respectively, if assumed this is a reliable 4 -hr LC50 value.
