For the members of the C7-C9 hydrocarbon solvents category only a single measured aquatic bioconcentration factor (BCF) value for octane (CAS 111-65-9) in the mussel, Mytilus edulis, has been reported as 199 (log BCF = 2.3) (Donkin et al. 1989). However, there are also calculated BCF values for other category members available in the range of 11.81 to 1216 (log BCF of 1.07 to 3.08)(BCFBAF version 3.00, a subroutine of the computer program EPI Suite™, 2000), including octane with a BCF and Log BCF of 1216 and 3.08, respectively.
