Description of key information

The substance exhibits a EC50(72 h) for aquatic alga and cyanobacteria of 1.2 mg/L and 0.45 mg/L in two QSARs.

The lowest obtained result is kept as key value for chemical safety assessment.

Key value for chemical safety assessment

EC50 for freshwater algae:
0.45 mg/L

Additional information

The QSAR determinations of the algae growth inhibition was based on validated data derived from 72 h ErC50 tests on algae, for which the concentrations of the test item had been determined by chemical analyses over the test periods.

These studies are considered acceptable and satisfies the guideline requirements for growth inhibition of algae study. Therefore, the lowest obtained result is used as key study for chemical safety assessment.
