(96 h) ErC50 2.7 mg/L S. capricornutum
(96 h) NOEC (growth rate) 1.0 mg/L S. capricornutum

Key value for chemical safety assessment

Additional information

A reliable 96 h EC50 value of 2.7 mg/L and a NOEC value of 1.0 mg/L based on growth rate have been determined for the effects of Alcohols, C9-11-linear and branched on the cell growth of the freshwater algae Selenastrum capricornutum (new name: Pseudokirchnerella subcapitata). This is the only reliable data and has been selected as key.
