Translocation, leaching, uptake by plants and degradation of hydrophobic organic pollutants are largely determined by the properties of the soil/sediments. The above properties influence those processes which directly or indirectly influence the bioavailability of pollutants. The factor which plays a decisive role in determining bioavailability/bioaccumulation of pollutants is sorption. Where sorption is concerned, such matrix properties as the presence, composition, properties of organic matter, type of clay materials, type and amount of other pollutants, etc. play an important role. The second part of the study is a review of the literature on the influence of hydrophobic organic pollutants with geosorbents acting through sorption. Matrix properties that can significantly influence this process have been described in detail.
