Applicant's summary and conclusion

Interpretation of results:
practically nontoxic
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Good quality atudy. No negative effects were observed. An LD 50 of > 2000 mg/kg bw was assessed
Executive summary:

The oral toxicity of copper slag was assessed during an acute toxicity limit test with rat. The test was performed according to EU B1 Method (Limit-test). All test animals were exposed to 2000 mg copper slag/kg bodyweight, administered by the feed. After 14 days of observation, none of the animals showed negative effects. An LD 50 of > 2000 mg/kg bw was assessed.

Therefore copper slag is considered as nontoxic via oral route.
