Aquatic chemistry is becoming both a rewarding and substantial area of inquiry and is drawing many prominent scientists to its fold. Its literature has changed from a compilation of compositional tables to studies of the chemical reactions occurring within the aquatic environments. But more than this is the recognition that human society in part is determining the nature of aquatic systems. Since rivers deliver to the world ocean most of its dissolved and particulate components, the interactions of these two sets of waters determine the vitality of our coastal waters. This significant vol ume.

This text is a result of a research project on the environmental behaviour of sediments. It represents the study of chemical and biological interactions of toxicants in sediments. The volume aims to provide insights into the actual international state of sediment quality assessment and discusses various chemical as well as biological approaches to sediment toxicity. The understanding of interactionsof toxic substances in sediments and of conditions controlling mobilization, transfer and bioavailability can be used to predict environmental fates and effects of chemicals. The text aims to provide information to governmental administrations, technical advisers and research institutions dealing with the management of contaminated sediments.

Few fields of research in the earth sciences have produced as much data and litera ture as the study of carbonate sediments and rocks. The past 25 years in particular, have seen a significant increase in studies concerning modern marine and fresh water carbonates. With the present worldwide interest in oceanographic research, marine carbonates have received the bulk of the attention, particularly with respect to shallow-water sediments. However, in terms of the variety of environ ments, compositions and modes of formation, non-marine carbonates probably encompass a wider spectrum than do ma.

This is the first interdisciplinary book on the mobilization of nutrients and pollutants in the water phase due to hydrodynamic processes. Coverage includes the formation of aggregates in turbulent water; flocks and biofilms from organic reactions; and the formation of new surfaces for re-adsorption of dissolved pollutants. The book gathers papers resulting from an International Symposium on Sediment Dynamics and Pollutant Mobility in River Basins in Hamburg, Germany, March, 2006.

"Heavy Metals: Problems and Solutions" is divided into three sections dealing with basic geochemical processes, remediation and case studies. The basic geochemical processes are discussed with respect to mobility in the environment and impact as well as methods to derive guidelines for heavy metals. Remediation focuses on currently available methods to treat contaminated sediments and soils. In addition, it considers the concept of geochemical engineering for remediation of large areas contaminated by metals. A number of case studies of polluted sediments and soils and their environmental impact highlight the principles discussed in the first two sections.
