Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Conclusions:
- The acute toxicity of the test material to freshwater invertebrate Daphnia magna has been investigated and gave a 48-hour EC50 of greater than 34 mg/L.
- Executive summary:
A study was performed to assess the acute toxicity for the test material to Daphnia magna. The method followed is described in the OECD Guidelines for Testing of Chemicals No.202.
The 48 -hour EC50 value for the test material to Daphnia magna was greater than 34 mg/L.
