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 Metal Contaminated Aquatic Sediments written by HerbertE. Allen and published by Routledge. This book was released on 2018-04-27 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

This book was released on 2006-01-15 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents new results on metal fluxes from society to the environment, on metal speciation in water, soil and sediment, and its mobility, biological uptake and toxicity. New approaches, like the Acid Volatile Sulphide (AVS) concept to predict metal bioavailability in sediments, and the Biotic Ligand Model to calculate the toxicity of metals to aquatic organisms, are critically evaluated, with a focus on copper, nickel, zinc, and, chromium.

Book excerpt: Describes how metals in sediments can become bioavailable, and therefore cause toxicity in the ecosystem. The paper identifies available information regarding sediment-bound trace metal toxicity (including copper) and suggests topics for future research.
Download or read book Heavy Metals written by Wim Salomons and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.
Download or read book Speciation of Metals in Water Sediment and Soil Systems written by Lars Landner and published by Springer. This book was released on 2006-04-10 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: The particular behavior of trace metals in the environment is determined by their specific physico-chemical form rather than by their total concentration. The introduction of atomic absorption spectrometry has lead to a plethora of scientific papers and reports in which metal concentrations in the environment are only reported as total concentrations. Only recently has the need for improved knowledge on the various forms and bioavailability of metals been realised. Considerable research effort is now devoted to measuring the concentrations of trace metals in surface waters. Efforts are made to couple chemical analytical techniques to process-related biological problems. The proceedings of the workshop on The Speciation of Metals in Water, Sediment and Soil Systems held in Sunne, Sweden, comprise these efforts and show aspects for further cooperation between analytical chemists and biologists.

Download or read book Biogeodynamics of Pollutants in Soils and Sediments written by Wim Salomons and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the USA, Western and Central Europe, there are many large-scale polluted sites that are too large to be cleaned up economically with available technologies. The pollution is caused by heavy industries to soils and sediments in waterways and reservoirs. Since these areas are expected to remain polluted for many years, it is necessary to take a long-term view to insure that the capacity to retain the contaminants is not diminished and to understand the potential for large-scale contaminant mobilization at these sites triggered by changing environmental conditions. This book provides information for predicting long-term changes and making risk assessments and describes the approach of geochemical engineering to handling large-scale polluted sites.

Download or read book Bioavailability of Contaminants in Soils and Sediments written by National Research Council and published by National Academies Press. This book was released on 2003-05-03 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.
