The aim of this book is to give a state-of-the-art presentation of suspended particulate matter (SPM) in lakes, rivers and marine areas, with a focus on the roles that SPM plays in aquatic ecosystems and on modelling. To the best of the author's knowledge, this is the first book of its kind, and this is remarkable because SPM is very important in aquatic sciences. It regulates the transport of all types of water pollutants in dissolved and particulate phases. It regulates water clarity and the depth of the photic zone, and, hence, also primary and secondary production. SPM regulates bacterioplankton production and biomass, and, thus, also mineralization, oxygen consumption and oxygen concentrations. SPM regulates sedimentation and the use of sediments as an historical archive, e.g. of water pollutants. These matters are discussed in this book, which also presents empirical and dynamical models for SPM based on the ecosystem perspective. The aim of these models is to structure existing knowledge on the factors regulating variations among and within aquatic systems of SPM in a rational and quantitative manner. This knowledge is fundamental for an understanding of the function and structure of aquatic systems. This book is intended as a textbook (mainly for Master's and Ph.D. students) in aquatic sciences, but it should also attract a considerable interest from researchers in limnology, marine ecology and environmental sciences, as well as from consultants and administrators interested in management and studies of aquatic systems. Dr. Lars Håkanson (Ph.D. in physical geography 1972, Uppsala University, Sweden) has been a professor in sedimentology (recent processes) at Uppsala University since 1992. He has been Chairman of IAEA ́s international aquatic program on Validation of Model Predictions (VAMP), 1988-1994, a member of the delegation for the Åland Foundation for the Future of the Baltic, 1989-1995 and Director of the International Association for Sediment Water Science (IASWS) 1981-1996. He was President of IASWS 1990-93. He is a member of the editorial boards of Environmental Geology and Aquatic Ecosystem Health and Management. He was awarded The Linné and Alfort Prizes for 1979. Dr. Håkanson has published 450 scientific papers and reports, including 13 international textbooks, 21 books/theses in Swedish and 20 contributions in international monographs.

The purpose of this book is to give an introduction to the most important aspects of suspended matter in the aquatic environment: its origin and composition, the concentration distribution, transport and deposition, and the most important physical-chemical-bio logical process that affects suspended matter: flocculation. In Chap ter 1 the development of suspended matter observation and study throughout history is given, with the coming of a more modern approach during the 19th century and the first half of the 20th century, and the development of the present science of suspended matter after 1945. The sources of suspended matter in rivers, lakes, estuaries, and the sea are discussed in Chapter 2, which includes the supply of detrital particles as well as the formation of new particles in the water (organic matter, carbonate, opal). The concentration distribution of suspended matter in rivers, lakes, estuaries, tidal is discussed in Chapter 3, to which is areas, lagoons, and in the sea added a discussion on the sampling of suspended matter and on methods to determine its concentration. Particle composition is treated in Chapter 4, to which is added a section (4. 6) on the compositional analysis of suspended particles. Also included is a discussion on particle surface characteristics and the adsorption of elements and compounds onto particles.

The Biology of Particles in Aquatic Systems, Second Edition presents the latest information on particulate and dissolved matter found in aquatic habitats ranging from small streams to oceans. Only by studying this matter can we gain an understanding of the functioning of aquatic ecosystems and thus be able to predict changes that may occur as these systems become stressed. Updated and extensively revised, this new edition covers such topics as classification of particulate and dissolved matter, origin and formation of particles aquatic systems, factors affecting particle aggregation, methods for capturing particles by benthic and planktonic animals, and the use of particulate and dissolved organic matter as food.

The present volume features fifty-seven papers presented at the international symposium «Suspended matter in rivers and estuaries» held at Reinbek, Germany, March 21--25, 1994. The contributions cover all aspects of particulate matter in aquatic environments. Topics span a wide range and can be divided in five principal groups: composition and properties of particulates, spatial and temporal variations of the distribution of particulate matter (scaling effects), particle-solute interactions, particle dynamics and transport processes and, as the result of the above processes,impact of particles and their absorbed load on the environment. Particulates in aquatic ecosystems are a complex phenomenon which demands to be approached multidisciplinarily, especially for the studies of rivers with variable water discharges and irregular flood events that perturb their particulate load and composition temporarily. At their estuaries, complexities are compounded by the effects of mixing of river water with tidal waters which change salinity and influence particle budget, size distribution and composition in space and time. Not only abiotic processes such as erosion, sedimentation and resuspension of inorganic particles brought about by the hydrographic forces, but also biological processes, like bacterial and algal aggregations on the particles, organic coating of the particle surfaces, colonization of the particles with heterotrophic organisms like Flagellates, Ciliates, Amoeba, Rotatoria and so forth, such forming microbiocoenoses on the flocs, numerous different biological activities and many more items are characterizing these complex aggregates. It is known that some fraction of nutrients but also toxic substances (e. g. pesticides) are bound to suspended particulate matter. Insight into the transport/precipitation mechanisms of these «hitchhiker» substances can hence only be gained by thorough understanding of particulate matter transport itself.

The aim of this book is to discuss practically useful (operational) bioindicators for sustainable coastal management, criteria for coastal area sensitivity to eutrophication and an approach set a "biological value" of coastal areas. These bioindicators should meet defined criteria for practical usefulness, e.g., they should be simple to understand and apply to managers and scientists with different educational backgrounds. Central aspects for this book concern effect-load-sensitivity analyses. One and the same nutrient loading may cause different effects in coastal areas of different sensitivity. Remedial measures should be carried out in a cost-effective manner and this book discusses methods and criteria for this. Remedial strategies should generally focus on phosphorus rather than nitrogen because the effects of nitrogen reductions can rarely be predicted well and nitrogen reductions may favour the bloom of harmful cyanobacteria. Three case-studies exemplify the practical use of the bioindicators and concepts discussed in the book. The first concerns how local emissions of nutrients affect the receiving waters when all important nutrient fluxes are accounted for. The second concerns how to find reference values for "good" ecological status to set targets for remedial actions. The third gives a reconstruction of eutrophication. If the development during the last 100 years can be understood, key prerequisites to turn the development would be at hand. This book should attract considerable interest from researchers in marine ecology, consultants and administrators interested in management and studies of coastal systems.
