Description of key information

The ECOSAR model v.1.11 (EPISuite v.4.10) estimated the 96 hour EC50 value to be 73.149 mg/L.

Key value for chemical safety assessment

EC50 for freshwater algae:
73.149 mg/L

Additional information

The toxicity potential of the test material to green algae was estimated using a validated QSAR model.

The structure-activity relationships (SARs) presented in this program are used to predict the aquatic toxicity of chemicals based on their similarity of structure to chemicals for which the aquatic toxicity has been previously measured. Most SAR calculations in the ECOSAR Class Program are based upon the octanol/water partition coefficient (Kow). Various surfactant SAR calculations are based upon the average length of carbon chains or the number of ethoxylate units.

The ECOSAR model v.1.11 (EPISuite v.4.10) estimated the 96 hour EC50 value to green algae to be 73.149 mg/L.
