Description of key information

The substance is a hydrocarbon UVCB. The adsorption of streams in this category has been predicted by calculating the log Koc of constituents with KOCWIN. The predicted log Koc of measured constituents of this category (at equal or above 0.1% w/w) range from 1.5 to 2.65. It is not feasible to perform adsorption/desorption tests in UVCB streams.

Additional information

The log Koc of measured constituents of this category (at equal or above 0.1% w/w) has been predicted using the EPISUITE v4.11 KOCWIN (2017) program, which uses methodology described by Sahljic et al., (1995) and Meylan et al. (1995). The predicted log Koc of constituents of these streams range from 1.5 to 2.65 (MCI method) and from 1.85 to 4.04 (log Kow method). The MCI model outperforms the log Kow model and covers a wider range of chemical structures. Therefore, more weight is given to the MCI-calculated Koc than the log Kow based Koc.
