Description of key information
(72 h) ErC50 0.23, EbL50 0.03 mg/L R. subcapitata
Key value for chemical safety assessment
Additional information
A reliable 72 h ErL50 value of 0.23 mg/L water accomodated fractions (WAFs) and a EbL50 value of based on growth rate an EC50 value of 0.084 mg/l WAFs and a NOELR value of 0.03 mg/L WAFs based on growth rate and biomass have been determined for the effects on Alcohols, C12-13, linear and branched on the freshwater algae Raphidocelis subcapitata.
Other reliable studies report ErL50s in the range 0.24 to 2.2 mg/L based on growth.
The presence of branched structures in some of the tested substances does not appear confer it any different ecotoxicological properties compared to the Alcohols, C12 -13 linears only substance.
