Above these carbon chain lengths, BCF values decrease below 2000. When biotransformation is incorporated into the model, none of the iso-paraffin BCF predictions are above 2000 (Figure 26). Experimental BCF values for iso-paraffins range from 673 (aqueous) to 6004 (dietary). Dietary BCF values, which are typically more conservative than aqueous BCF values, are above the B criterion for selected C9, C11 and C12 structures. Aqueous BCF data for 2,2,4,6,6-pentamethylheptane which is a highly branched, atypical structure indicates the B criterion maybe fulfilled (Figure 27). For all tested C13, C15 and C16 structures dietary calculated BCFs exceed 2000 (Table 12). However, reliable aqueous BCF data for C15 and C16 structures indicate these compounds do not fulfill the B criterion but do 32
exhibit BMFs near unity (Figure 28). It can be concluded that based on the available data, C12-C16 iso-paraffins may be bioaccumulative (B), but not very bioaccumulative (vB).
