The adsorption coefficient (Koc) on soil and
sewage sludge of 1,1'-(1,1,2,2-tetramethylethylene)dibenzene was
assessed according to EU method C.19 and OECD guideline no. 121 using
the HPLC method. Based on the retention time measured for
1,1'-(1,1,2,2-tetramethylethylene)dibenzene (8.25 min), the log Koc was
estimated to be 4.20 ± 0.007 (95 % confidence interval) corresponding to
a Koc of 15968 ± 254.8 (95 % confidence interval) at 25 °C.
The Koc of the test item was determine
using the HPLC method to be 15968 ± 254.8 (95 % confidence interval) and
the log Koc to be 4.2 at 25 °C, respectively.
