After exposure to soil, significant adsorption of 2-ethylhexanoic acid to solid soil phase (e.g. clay) is not expected. Due to its low Henry's Law constant and because the substance occurs mainly in its anionic form under environmental conditions, evaporation from the water surface is not expected. The distribution of the substance between the environmental compartments was calculated by use of the Mackay LEVEL 1 v3.00 programme. The standard environmental properties for the calculation are drawn from a publication of Mackay (2001). Due to the results of the Mackay LEVEL 1 calculation, over time the substance will preferentially distribute into water
