Additional information

Hydrocarbons, C12-C16, n-alkanes, isoalkanes, alkenes is an extremely complex hydrocarbon UVCB. The substance is comprised of 23 different categories of components. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance.

As a result, the potential bioaccumulation of representative structures from each category of components identified in Hydrocarbons, C12-C16, n-alkanes, isoalkanes, alkenes has been calculated using the BCFBAF model (v3.01) found in the US EPA’s EPISuite (v4.11) group of QSAR models. The calculated BCF values (Arnot-Gobas Upper Trophic) ranged from 1 to 2278 L/kg wet-wt.

Based on the results, only few structures of Hydrocarbons, C12-C16, n-alkanes, isoalkanes, alkenes (C12 iso alkane, C12 alkene and C14 linear alkane in the whole carbon range of the categories) meet the Bioaccumulative (B) criteria.
