Different soil samples and synthetic goethite were reacted with Gamma-HCH, anthracene, 2,4-D and atrazine in a solid/water and a solid/oil system. The non-polar compounds Gamma-HCH and anthracene were only sorbed from aqueous solution, in particular by soil samples with a high content of organic carbon. When dissolved in oil these non-polar compounds were not sorbed by any of the soil samples investigated. For atrazine, little sorption was observed whereas for 2,4-D, sorption from the oil phase was much higher than from aqueous solution. This effect is problbly connected to modifications of the electric double layer on the particle surfaces.
