Book Description
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.

Book Description
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.

Book Description
This book describes how man-made litter, primarily plastic, has spread into the remotest parts of the oceans and covers all aspects of this pollution problem from the impacts on wildlife and human health to socio-economic and political issues. Marine litter is a prime threat to marine wildlife, habitats and food webs worldwide. The book illustrates how advanced technologies from deep-sea research, microbiology and mathematic modelling as well as classic beach litter counts by volunteers contributed to the broad awareness of marine litter as a problem of global significance. The authors summarise more than five decades of marine litter research, which receives growing attention after the recent discovery of great oceanic garbage patches and the ubiquity of microscopic plastic particles in marine organisms and habitats. In 16 chapters, authors from all over the world have created a universal view on the diverse field of marine litter pollution, the biological impacts, dedicated research activities, and the various national and international legislative efforts to combat this environmental problem. They recommend future research directions necessary for a comprehensive understanding of this environmental issue and the development of efficient management strategies. This book addresses scientists, and it provides a solid knowledge base for policy makers, NGOs, and the broader public.

Book Description
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.

Book Description
This literature review of the effects of turbidity and suspended material in aquatic environments covers the following subjects: definitions, units of measure, and methods of measurement; origins; and effects in aquatic environments. Turbidity, regardless of the multiplicity of definitions, units of measure, and methods of measurement, is an expression of the optical properties of water that cause light to be scattered and absorbed rather than transmitted in a straight line. Turbidity is not the same as siltation, although the terms have been used synonymously in the past. The various units of measure include the Jackson Turbidity UNIT (JTU), Formazin Turbidity Unit (FTU), and Nephelometric Turbidity Unit (NTU). The methods of measuring percent transmission or the weight per volume concentration of suspended particulates are based on either gravimetric or optical techniques.

Book Description
The impacts of siltation and suspended sediments on water quality and resident aquatic organisms is one of the most common problems facing resource managers today. Most construction activities in or near a watercourse have the potential to result in decreased shoreline stability and/or an increase in siltation, suspended sediments and turbidity. This annotated biliography was prepared in response to requests from seveal Ontario Ministry of Natural Resources biologists and technicians in the Southern Region. The author attempted to assemble and summarize reference material on various aspects of this topic including sources of suspended solids, physical/chemical processes, impacts to water quality and aquatic life, and remediations. This bibliography is intended to prove a consolidation and synthesis of information which is readily available for day-to-day use by field staff. Almost 1200 references are cited.

Book Description
This book is open access under a CC BY 4.0 license. This volume focuses on microscopic plastic debris, also referred to as microplastics, which have been detected in aquatic environments around the globe and have accordingly raised serious concerns. The book explores whether microplastics represent emerging contaminants in freshwater systems, an area that remains underrepresented to date. Given the complexity of the issue, the book covers the current state-of-research on microplastics in rivers and lakes, including analytical aspects, environmental concentrations and sources, modelling approaches, interactions with biota, and ecological implications. To provide a broader perspective, the book also discusses lessons learned from nanomaterials and the implications of plastic debris for regulation, politics, economy, and society. In a research field that is rapidly evolving, it offers a solid overview for environmental chemists, engineers, and toxicologists, as well as water managers and policy-makers.
