Description of key information

The log Kow range for Litsea cubeba oil constituents (calculated using KOWWIN v1.67 QSAR) was found to be 2.06 - 6.3 (16.90% of the constituents has a log Kow >= 4).

The bioaccumulation potential for aquatic species and terrestrial species is based on predicted log Kow ranges (2.06 - 6.3) of the constituents and calculated BCF values using QSARs of Veith and Jäger, yielded min-max BCF ranges of 11.2 - 45186 L/kg ww for fish and 2.22 - 23944 L/kg for earthworms. The potential for bioaccumulation strongly differs between constituents and can not be concluded for the whole UVCB.
