Additional information

The adsorption coefficient (Koc) on soil and on sewage sludge using high performance liquid chromatography (HPLC) has been estimated andadsorption coefficients estimated to be log Koc,soil = 21.41 and log Koc, sewage sludge = 23.21. These values correspond to a Koc,soil = 2.582E21 and Koc,sewage sludge = 1.642E23. The McCall classification scheme classifies the substance as immobile in soil (Koc > 5000).

[LogKoc: 21.41]
