Description of key information
According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE , a bioaccumulation study need not be conducted if:
— the substance has a low potential for bioaccumulation (for instance a log Kow ≤ 3) and/or a low potential to cross biological membranes, or
— direct and indirect exposure of the aquatic compartment is unlikely.
The estimated Log BCF of Alcohols, C12-14 is 1.677 (BCF = 47.59 L/kg wet-wt)
This substance has a limited potential to bioaccumulate (based on log Kow used by BCF estimates: 5.13, and predicted bioconcentration factors, log BCF = 1.677 (EPIWIN/BCF Program).
The estimated BCF of 47.59 L/kg wet-wt was measured by calculation from EPI SuiteTM v4.1 Program.
These values would suggest very low bioaccumulation potential.
This is Exposure Assessment Tools and Models made from EPA (Environmental Protection Agency).
