Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- In an OECD203 limit test no toxicity to fish (Danio rerio) could be determined up to a nominal concetration of 1000 mg/L (96h).
- Executive summary:
In an OECD203 limit test no toxicity to fish (Danio rerio) could be determined up to a nominal concetration of 1000 mg/L (96h).
