Any other information on results incl. tables

The organic carbon-normalised partition coefficient was estimated by considering the equation for non-hydrophobic substances reported in the EU TGD (2003) and the experimentally determined log Kow (1.06).

log Koc = 0.52 log Kow + 1.02 = 0.52 x 1.06 +1.02 = 1.5712

Therefore Koc = 37.26 l / kg
