measured Koc is not available for any of the streams in this category.
As the log Kow of some streams is >3 the adsorption/desorption endpoint
cannot be waived. However, ECHA's Guidance on Information Requirements
and Chemical Safety Assessment R7a Endpoint Specific Guidance (2008)
indicates that, before commissioning a new study, alternative sources of
data (e.g. QSAR) on the adsorption/desorption potential of a chemical
should used. Soil
sorption of non-ionic substances can be estimated from their log Kow.
Several QSAR have been developed that calculate the Koc of non-polar
hydrocarbons on the basis of their log Kow (e. g. Sabljic and Gusten,
1995). The log Kows for representative components on these
streams were identified from the compositional data. The representative
components are presented in Section 2.3.
The predicted log Kocs for the
representative components in this category range from 1.34 to 6.67 and
the mean is 3.26.
