Download or read book Metal Pollution in the Aquatic Environment written by U. Förstner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 provides not only an introduction to the dynamics of aquatic chem istries but also identifies those materials that jeopardize the resources of both the marine and fluvial domains. Its very title provides its emphasis but clearly not its breadth in considering natural processes. The book will be of great value to those environmental scientists who are dedicated to keeping the resources of the hydrosphere renewable. As the size of the world population becomes larger in the near future and as the uses of materials and energy show parallel increases, the rivers and oceans must be considered as a resource to accept some of the wastes of society. The ability of these waters and the sediments below them to accommodate wastes must be assessed continually. The key questions relate to the capacities of aqueous systems to carry one or more pollutants.

Download or read book Complexation of trace metals in natural waters written by C.J. Kramer and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is presently well recognized that total concentrations of trace elements in any environmental compartment supply insufficient information to understand important phenomena. The distinction and separate analysis of specific chemical species are essential for understanding cycles in the aquatic environment, involving identification and quantification of sources, transport pathways, distributions and sinks, or, in the area of interactions between trace elements and organisms to understand uptake, distribution, excretion mechanisms and effects. In the past, various ways have been developed to determine the nature and extent of complexation of trace elements in natural systems. Approaches have been followed along very different lines. These have not always been fully appreciated by specialists working in even related fields of complexation research. The first International Symposium on the Complexation of Trace metals in Natural Waters was held at the Netherlands Institute for Sea Research (NIOZ, Texel, the Netherlands from 2-6 May 1983. The scientific programme was planned by the chief organizers Drs. C.J.M. Kramer and J.C. Duinker (NIOZ) together with Prof. Dr. H.W. Nurnberg (Kernforschungsanlage, Julich, Federal Republic of Germany) and Dr. M. Branica (Rudjer Boskovic Institute, Zagreb, Yugoslavia).

Download or read book Trace Metals in the Environment written by Daisy Joseph and published by BoD – Books on Demand. This book was released on 2023-09-27 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: High levels of toxic elements have harmful effects on all aspects of the environment (water, air, plants, etc.). Trace elements, many of which are heavy metals, can compromise soil quality, cause toxicity to plants, and ultimately contaminate the food chain. This book summarizes the effects of trace elements in the environment. Section 1 discusses the influence of trace elements on soil and the ecosystem and Section 2 examines the influence of trace elements on water. The book also discusses microplastics, which accumulate trace elements and pollute the oceans, harming both aquatic and human life.
Download or read book Trace Metals in Aquatic Systems written by Robert P. Mason and published by John Wiley & Sons. This book was released on 2013-02-20 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a detailed examination of the concentration, form and cycling of trace metals and metalloids through the aquatic biosphere, and has sections dealing with the atmosphere, the ocean, lakes and rivers. It discusses exchanges at the water interface (air/water and sediment/water) and the major drivers of the cycling, concentration and form of trace metals in aquatic systems. The initial chapters focus on the fundamental principles and modelling approaches needed to understand metal concentration, speciation and fate in the aquatic environment, while the later chapters focus on specific environments, with case studies and research highlights. Specific examples deal with metals that are of particular scientific interest, such as mercury, iron, arsenic and zinc, and the book deals with both pollutant and required (nutrient) metals and metalloids. The underlying chemical principles controlling toxicity and bioavailability of these elements to microorganisms and to the aquatic food chain are also discussed. Readership: Graduate students studying environmental chemistry and related topics, as well as scientists and managers interested in the cycling of trace substances in aqueous systems Additional resources for this book can be found at: www.wiley.com/go/mason/tracemetals.
Download or read book Metal Contaminated Aquatic Sediments written by Herbert E. Allen and published by CRC Press. This book was released on 1996-01-01 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade the sediments of many rivers, lakes, and estuaries have been contaminated by inorganic and organic materials. Contaminants from sediments, under certain conditions, can be released into overlying waters. Thus, sediments may be an important source of contaminants to waters in which littoral and atmospheric contaminants have been reduced or eliminated. Often found in aquatic sediments, metals are exposed to many reactions, such as sorption and precipitation, and are greatly influenced by the redox conditions in the sediment. The reactions - usually over a period of time - reflect biotic processing as well as chemical transformations. This book describes these important processes. Metal Contaminated Aquatic Sediments outlines advances in environmental chemistry, effective new modeling techniques, applications for biological treatment, and cycling and transport of trace metals in sedimentary environments. Each chapter contains a detailed reference section that draws upon a stunning array of sources. The book includes many figures and tables that illustrate the process under discussion. Features

Download or read book Trace Metals in Estuarine and Coastal Waters written by Camille Gaulier and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estuarine and coastal ecosystems provide multiple ecological, social and economic services. They are a source of food, income and are at the heart of marine trade, merchant shipping and sea transport. They therefore play a key role in our modern world and their conservation from an environmental point of view is today critical. Despite all the efforts done in environmental management, pollution associated with the rapid coastal development and intensive industrialization was inevitable and still remains one of the main threats towards marine ecosystems today. Specifically, trace metal contamination is of specific concern as coastal areas are generally prone to accumulate them. Most trace metals exhibit a dual role in marine waters: they act as nutrients in low concentrations, yet rapidly have toxic effects in higher concentration ranges. Continuous monitoring of their concentrations in estuarine and coastal ecosystems is therefore needed to better understand their biogeochemical behavior in such marine environments. However, limited knowledge exists on their bioavailability towards marine organisms: especially as the toxicity of these metals is not only related to their concentration but also strongly linked with their speciation which shows both seasonal and spatial variations. Thus, the main objective of this PhD research was to investigate the biogeochemical cycles of various trace metals and unravel their speciation and bioavailability in various aquatic systems: from very dynamic mixing zones of the Scheldt estuary to coastal harbors and shallow seawaters of the North Sea, and even to deeper and anoxic regions of the Baltic Sea. Trace metal concentrations and speciation were explored seasonally and spatially along horizontal and vertical gradients, and a comparison of classic active samplings of dissolved trace metals with a passive sampling technique (Diffusive Gradients in Thin-films; DGT) was carried out. The DGT technique was successfully used for the in-situ measurement of labile metals and eventually constitutes a good surrogate to the biomonitoring of trace elements (e.g. use of mussels, algae, etc.). This method offsets the lack of knowledge in terms of water quality monitoring and the results challenge the classic criteria which are used by international regulatory requirements (e.g. WFD, MSFD) and local commitments (e.g. OSPAR, HELCOM). Indeed, new criteria based on labile metal species instead of total dissolved species should be considered in the future. Such approach of trace metal speciation and assessment in aquatic systems could surely lead to a more integrated environmental management and improve our knowledge on anthropogenic impacts and pollutant fluxes. Moreover, it is eventually the main key to explain and predict bioavailability and potential toxicity of trace metals to the marine fauna and flora. This work therefore invites you to dive into a journey along our coasts, from urbanized areas to wild open seas, from their surface to their deepest waters.
