BioHCwin (Y-axis) vs. experimental half-lives (X-axis) for di-naphthenic hydrocarbons 3.5 Poly-Naphthenic hydrocarbons The BioHCwin model predicts that half-lives for poly-naphthenic hydrocarbons above C13 will be higher than 60 days (Figure 9). Experimental marine degradation half-lives for poly-naphthenic hydrocarbons up to C19 range from 6.1 to greater than 191 days (Table 5). In several cases, there are data for multiple hydrocarbons with the same number of carbons. Up to C15 and for some C18 and C19 structures half-lives are below the persistence criterion. However, some C16 and C18 structures have experimental halflives clearly exceeding the persistence criterion although BioHCwin predictions for structures with experimental half-lives above 60 days are in many cases overly conservative (Table 5, Figure 10). It can be concluded that for poly-naphthenic hydrocarbons at or above C16, some structures will exhibit half-lives above the persistence criterion. 16
