ABSTRACT
As discussed in the previous chapter, sediments consist of solids, pore water, and gases. The interactions of the pore water with the contaminants and the solids are complex and are to be discussed in this chapter. It is important to understand the physical and physicochemical interactions of the contaminants with the sediment solids to understand the capacity of retention of the sediments and potential parameters for contaminant release. Sediment composition, properties, and characteristics will inuence the interactions at the sediment-pore water interface. The reactions between a pollutant and sediment will determine its transport through the sediments, and also its fate.
