Experimentally derived fish BMFs for naphthenic di-aromatic hydrocarbons (NDiAr) from dietary bioaccumulation studies 4.10 Poly-Aromatics Regression method BCF predictions for poly-aromatic hydrocarbons structures (Figure 57) are above the B criterion of 2000, ranging from C15 to C28. When biotransformation is incorporated to the model, BCF predictions are above 2000 for one C25 structure (Figure 58). There is a very large experimental BCF dataset available for poly-aromatic hydrocarbons (Table 20). With the exception of anthracene, phenanthrene and o- terphenyl model predictions and reliable BCF data indicate that these substances do not meet the B criteria. There are three terphenyl isomers (o-. m-, and p-terphenyl), two of which do not meet the B criterion. The third, o-terphenyl, meets the B criterion in two of three studies, including an aqueous BCF study. Anthracene has been determined to be a PBT substance by the ECB TC-NES PBT Working Group. At the time of the release of this assessment, o-Terphenyl has not been decided. A compilation of dietary and aqueous BCFs (Figure 59), laboratory BMFs (Figure 60) and field BSAFs (Figure 61)(USEPA, 2008) and TMFs (Table 21)(Wan et al. 2007; Nfon et al, 2008; Takeuchi et al. 2009) support the general conclusion that poly-aromatic hydrocarbons (PAH) do not meet the B or vB criteria. In fact, available data provide a compelling case that PAH are not biomagnified but rather, undergo trophic dilution in the field thereby limiting exposure via the foodchain. This is supported further by other studies that do not present TMF data, but show evidence of PAH metabolism (Broman et al. 1990; D’Adamo et al. 1997) Therefore, it can be concluded that based on the available data, only C14 poly-aromatic hydrocarbons (e.g. anthracene and phenanthrene) meet the B criterion. 55
