The calculated log Koc values for substances in this category range from 1.315 - 6.256. The range in values is considered to be due to different constituents within the UVCB having different adsorption potential.
these are poorly soluble UVCB substances it is extremely difficult to
measure a Koc value experimentally. The Koc values for these substances
have therefore been calculated based on an experimental Kow value,
following the equation in the EU Technical Guidance Document (2003) and
the ECHA Guidance Document R7a (2008): log Koc = 0.81 Log Kow + 0.1.
