C17 -C19, n-alkanes, <2% aromatics are hydrocarbon UVCBs. Standard tests
for this endpoint are intended for single substances and are not
appropriate for this complex substance. However, this endpoint is
fulfilled using quantitative structure property relationships for
representative hydrocarbon structures. The BCFBAF 3.01 model is a well
characterised and generally accepted bioaccumulation prediction model,
used by the USEPA, the OECD and recommended by ECHA. The SMILES input
data for the BCFBAF 3.01 model is obtained from the PETRORISK Product
Library (see OECD QSAR Toolbox report in 'Attached full study report'
and PETRORISK report attached in IUCLID section 13).
The calculated BCF of Hydrocarbons, C17
-C19, n-alkanes, <2% aromatics ranges from 4.33 - 5614.57 L/kg.
v2.16 model within EPISuite 3.12 has been used to estimate the
bioaccumulation potential of a number of representative substances. This
data is used as a weight of evidence alongside the data reported above.
calculated BCF of the representative substance icosane is 22 L/kg
the BCFWIN v2.16 model within EPISuite 3.12.
This value indicates that icosane is not considered a bioaccumulative
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.
