Description of key information

(Q)SAR estimations for the registered substance resulted in a 96 hr EC50 of 4.589 mg/L; and chronic value (ChV) to green algae of 1.636 mg/l, equivalent to a NOEC of 1.157 mg/l.

Key value for chemical safety assessment

EC50 for freshwater algae:
4.589 mg/L
EC10 or NOEC for freshwater algae:
1.157 mg/L

Additional information

Experimental long-term toxicity data for the registered substance are not available. A chronic aquatic toxicity value was calculated using the neutral organics structure-activity relationship in the ECOSAR computer program of EPISuite; the results of which are adequate for the purpose of classification and labelling and/or risk assessment. Validity and applicability of the QSAR are described in a document attached as background material to the QSAR endpoint study record.
