Table 2 : PBT assessment of C11 – C19 monocyclic naphthenic metabolites when compared to the parent structures Name C# LogKow L(E)C50 Primary Bioacumulation half-life n-Heptylcyclopentane 12 6.05 Metabolite 1 1.87 +++ >>>> >> > > < Metabolite 3 2.36 + >>>> >>> < 1-cyclohexyl 4,8 dimethyl undecane 19 9.34 Metabolite 1 8.10 < Metabolite 2 8.10 < 120

1: The following structures were predicted to have no stable metabolites: n-hexylcyclopentane, isohexylcyclopentane, 1,2,3,4-tetraethylcyclohexane, iso-nonylcyclohexane, 1,5-dimethyl-1-(3,7- dimethyloctyl)cyclohexane, 1,5-dimethyl-1-(3,7-dimethylnonyl)cyclohexane 2: each symbol indicates the order of magnitude greater or less for the metabolite when compared to the parent molecule. 121
