Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references (pages 20-26). "Many toxical chemicals in aquatic systems are associated with the cohesive sediment phase (silt & clay). In rivers, chemical management and the prediction of chemical pathways and fate requires a significant improvement in knowledge of the physics, chemistry and microbiology of cohesive suspended and bottom sediments. The principal knowledge gaps are identified and specific examples of importance of the cohesive fraction for toxicology flocculation, modelling and chemical partitioning are provided"--Management perspective.
