Applicant's summary and conclusion

Conclusions:
The study was performed as a limit-test with the concentration 100mg/l. Twenty daphnia were exposed to the test item for 48 hours in a static test
system. After 24 and 48 hours, the immobilized daphnia were counted.
None of the animals were immobilized in the control and in the treatment level of 100mg/l.
The following results could be determined for the test item BIBR 1048 Diamin (species: Daphnia magna)
24h and 48h NOEC = 100mg/l
24h and 48H EC50 > 100mg/l
