Applicant's summary and conclusion

Conclusions:
No adverse effects were observed.
Executive summary:

The toxicity to aquatic invertebrates was studied in an acute immobilization test on Daphnia magna accroding to OECD 202. The daphnids were exposed to the test compound over a period of 48 hours in a limit test at the solubility limit (9.3 mg/L). No effects were observed in the test organisms. Thus, the EC50/48h in Daphnia magna is higher than a saturated solution of the test compound. The test was performed according to GLP (report X153, study TX96148).
