Description of key information

Both an aqueous exposure bioconcentration test and a dietary exposure bioaccumulation test with Alcohols, C11-14-iso, C13-rich were conducted with the rainbow trout, Oncorhynchus mykiss. In the aqueous exposure, the trout reached steady-state within a 10-day exposure period. The calculated mean lipid-normalized steady-state BCF(ssl) was 39 L/kg wet fish weight. The calculated dietary, lipid-corrected BMF values were 0.010 to 0.016 (at 500 and 2500 ppm treatment levels), with growth corrected whole body half-lives ranging from 0.39 to 0.58 days. Both the aqueous and dietary bioaccumulation studies indicate that this substance exhibits a low potential to bioaccumulate.

Additional information

A BCF study with Alcohols, C11 -14 -iso, C13 -rich was conducted with the rainbow trout, Oncorhynchus mykiss. There was no difference in mortality, growth, or lipid content between the exposure solutions and the control after 10 days of exposure or at the end of the study (14 days). The exposed trout reached steady-state within the 10 -day exposure period. The calculated mean lipid normalised steady-state BCF after 10 days of exposure was 39 L/kg wet fish weight. Therefore, this substance exhibits a low potential to bioconcentrate.

A dietary bioaccumulation study with Alcohols, C11 -140iso-, C13 -rich was conducted with the rainbow trout, Oncorhynchus mykiss. The calculated dietary, lipid-corrected BMF values were 0.010 to 0.016 (at 500 and 2500 ppm treatment levels), with growth corrected whole body half-lives ranging from 0.39 to 0.58 days. Therefore, this substance exhibits a low potential to bioaccumulate.
