depending on the nominal concentration after 48 hours a loss of 44 -81% of test substance concentration was observed

Validity criteria fulfilled:
not specified
Conclusions:
According to the test results ( acute daphnia test and not readily biodegradable) the substance has to be classified with H 412, aquatic chronic 3
