Description of key information

The 72h growth rate ErC50 and ErC10 values were 2.0 and 0.83 mg/L, respectively for Pseudokirchneriella subcapitata (OECD 201, static) exposed to Alcohols, C9-C11, branched.

Key value for chemical safety assessment

EC50 for freshwater algae:
2 mg/L
EC10 or NOEC for freshwater algae:
0.83 mg/L

Additional information

Experimental toxicity data for the registered substance are adequate for the purpose of classification and labelling and/or risk assessment. Supporting information is provided by acute and chronic aquatic toxicity values calculated using the neutral organics structure-activity relationship in the ECOSAR computer program (Nabholz and Mayo-Bean, 2009) of EPISuite; the results of which are consistent with the measured test data. Validity and applicability of the QSAR are described in a document attached as background material to the QSAR endpoint study record.
