4.3 Mono-Naphthenic hydrocarbons The regression-based BCF predictions for mono-naphthenic hydrocarbons (Figure 29) are above the B criterion of 2000 for structures ranging from C11 to C18. Above these carbon chain lengths, BCF values decrease below 2000. When biotransformation is incorporated into the model, only one C12 BCF prediction is above 2000 (Figure 30). Experimental BCF values for mono-naphthenic hydrocarbons range from 77 (aqueous) to 4614 (dietary). Dietary BCF values are above the B criterion for many of the tested structures, which range from C9 to C14 (Table 13). Aqueous BCF data are limited but data for a C8 structure indicates the B criterion is fulfilled (Figure 31). Experimental BMF factors, derived from the dietary data (Figure 32), are always below 1 suggesting that calculated dietary BCFs may overstate bioaccumulation potential at least for some structures. It can be concluded that based on the available data, mono-naphthenic hydrocarbons below C8 are not bioaccumulative, and that some C8-C14 mononaphthenic hydrocarbons may meet the bioaccumulative criterion (above 2000), but do not exceed 5000, therefore are not very bioaccumulative (vB).
