Description of key information

A measured Koc is not available for any of the streams in this category but as the log Kow of some streams is >3, the adsorption/desorption endpoint cannot be waived.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 Kow of eight representative components of the streams in this category fall within the applicability domain of this model. The calculated log Koc are in the range 2.4 to 3.6.
