Studies on adsorption could not be conducted for this substance due to issues with technical feasibility. However, a QSAR has been conducted to estimate the adsorption coefficient for the purpose of the risk assessment. The estimated log Koc ranges from 7.5958 to 9.6238.
Due to the UVCB nature of the substance and the fact that accurate
analytical methods were not available for the material, the standard
tests for adsorption/desorption were not technically feasible. As such,
it was considered that a QSAR was necessary to provide the information
on adsorption for the risk assessment.
The QSARs were conducted for a component of the material that was
considered to be representative. The adsorption coefficient was
estimated for this component using KOCWIN v2.00, with estimates based on
both molecular connectivity index and an estimated log Kow value. The
estimated log Koc from the MCI method was 9.6238(Koc = 4.205x108L/kg).
The estimated log Koc from the octanol:water partition coefficient was 7.5958
It is likely that these Koc values are underestimates as
the material is known to have ionic and cationic properties which would
increase the adsorption coefficient. As such, the higher estimated log
Koc of 9.6238 is likely to be a more representative value.
All available evidence strongly indicates that the
substance will have a very high adsorption coefficient. For the purposes
of the risk assessment the Koc has been set to 1x106L/kg.
This is the maximum recommended value for the models which have been
used for the risk assessment, and as the values calculated by QSAR are
in excess of this, it is considered to be the most appropriate value for
