Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Conclusions:
- The 48-hr LC50 of the test substance was >10000 mg/L.
- Executive summary:
The acute toxicity of the test substance to fish was determined in a limit test. 10 fish were exposed to a concentration of 10000 mg/L of test substance. No mortality was observed in either the test or control groups. The fish 48-hr LC50 of the test substance is >10,000 mg/L.
