Applicant's summary and conclusion
- Executive summary:
The 48–hr-acute toxicity to Daphnia magna was studied under semi-static conditions.Daphnids were exposed to the test chemical at nominal concentrations of control, 1.0, 10.0, 100 mg/L for 48 hr. Immobilization effects were observed 24 and 48 hrs.
The 48 – hour EC50was 42.0 mg./L.
