Additional information
Conclusion on classification
Based on the toxicity data on growth inhibition in algae (72-h EC50 = 0.071 mg/L) the test substance is classified as Aquatic Acute 1. A m-factor of 10 is applied, since ’0.01 < L(E)C50 < 0.1’.
The substance does not meet the criteria to be classed as readily biodegradable and the log Kow > 4, therefore the substance is classed as Aquatic Chronic 1 based on 72-h EC50 = 0.071 mg/L for algae. A m-factor of 1 is applied, since ‘0,01 < NOEC ≤ 0,1’.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
