Description of key information

Bioaccumulation: aquatic/sediment

The calculated BCF of the representative substance icosane is 22 L/kg cacluated byusing the BCFWIN v2.16 model within EPISuite 3.12. This value indicates that icosane is not considered a bioaccumulative substance.

Bioaccumulation: terrestrial

C14-20 Aliphatics (≤2% aromatic) are hydrocarbon UVCBs. Standard tests for this endpoint are intended for single substances and are not appropriate for these complex substances. However, this endpoint has been calculated for representative hydrocarbon structures using the BCFWIN v2.16 model within EPISuite 3.12 as input to the hydrocarbon block method incorporated into the PETRORISK model. The predicted BCFs for hydrocarbons are generally overly conservative since biotransformation is not quantitatively taken into account. Therefore, indirect exposure and resulting risk estimates predicted by PETRORISK are likely to be overestimated. For the purposes of PBT assessment, measured bioaccumulation data for representative hydrocarbon constituents have been used as detailed in section 8 of the CSR.
