Description of key information

(48 h) ErC50 14 mg/L P. subcapitata, read-across from a structural analogue, the linear isomer octan-1-ol.

Key value for chemical safety assessment

Additional information

A 48h EbC50 of 6.5 mg/L and ErC50 of 14 mg/L have been determined for the effect of the octan-1-ol on biomass and growth rate respectively of Pseudokirchnerella subcapitata. The study reflects the lowest reliable value that is available for this endpoint and has been read-across to 2-methyl-1-heptanol.
