Conclusion on classification

The acute toxicity data report unbounded L(E)C50 of >100, >100, and >56 mg/L for fish, daphnia and algae, respectively. Because the mean recovery values of the test termination was less than 80% (67%) compared to test initiation (97%), the EC50 value needed to be calculated as geometric mean of the measured data which resulted in a EC50 of >56 mg/L. Since the chronic EC50 value was higher than 1 mg/L, there is no need for SVS to be classified for the aquatic environment.
