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 Modeling the Fate and Effect of the Toxic Substances in the Environment written by S Jorgensen and published by Elsevier. This book was released on 2013-10-22 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling the Fate and Effect of the Toxic Substances in the Environment contains the proceedings of a Symposium on "Modeling the Fate and Effect of Toxic Substances in the Environment", held on June 6-10, 1983 in Copenhagen, Denmark, and sponsored by the International Society for Ecological Modeling. The symposium provided a forum for discussing the state of the art in modeling the fate and effect of toxic substances in the environment. Topics include parameter estimation, theoretical considerations, and models of a wide variety of toxic compounds in aquatic and terrestrial ecosystems. Comprised of 16 chapters, this volume begins with an account of parameter estimation in toxic substance models, followed by a discussion on extinction and persistence in models of population-toxicant interactions. The reader is then introduced to PATHWAY, a simulation model of the transport of radionuclides through agroecosystems. Subsequent chapters focus on possible cause-effect relationships in the dying of Germany's spruce-fir forests; application of risk and uncertainty analysis techniques to a heavy metal speciation model; the biological effects of toxicants in aquatic microcosm systems; and the dispersal and biological effect of toxins in the Tamar estuary in England. The book concludes with a description of a nonlinear mathematical model for the transport and spreading of oil slicks. This book will be useful to students, practitioners, and researchers in the field of inorganic chemistry, as well as those who are interested in the environmental effects of toxic compounds.

This book was released on 2016-04-19 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most reported incidents of soil contamination include an array of heavy metals species rather than a single ion. The various interactions in these multicomponent or multiple-ion systems significantly impact the fate and transport of heavy metals, and competition for sorption sites on soil matrix surfaces is a common phenomenon. Because of this, con
Download or read book Modeling Mercury Transport and Transformation in the Aquatic Environment written by Andrew E. Bale and published by . This book was released on 1995 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many heavy metals are recognized as toxic to aquatic life in minute concentrations. Small amounts of these metals may be bioaccumulated up the food chain, throughout which they can cause disorder and death. Mercury is such a potentially harmful heavy metal and methyl mercury (MeHg), an organic species of mercury, has been found in relatively high levels in fish and invertebrates throughout the world. To effectively evaluate both the potential for harmful bioaccumulation and proposed measures to mitigate that harm, the spatial and temporal distribution of heavy metals within an aquatic system must be characterized. This dissertation provides background on mercury in the environment, reviews numerical models of mercury transport and speciation, and describes the construction and application of a numerical model, RMA4Hg, representing mercury transport and transformation in the aquatic environment.

Download or read book Freshwater Microplastics written by Martin Wagner and published by Springer. This book was released on 2017-11-21 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Prediction of the Environmental Fate of Chemicals written by Y. Samiullah and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern over the effects of chemicals in the environment has been increasing for many years. Environmental contamination by DDT, Aldrin, Dieldrin, mercury, PCBs, organotins and many other sub stances are all part of the public consciousness and have led to widespread attention to this topic. Some of the concerns have arisen because human health has been affected when contaminants have been consumed via the food chain-for instance in the case of 'Minimata disease' in Japan. In other cases, direct effects on other components of ecosystems have given cause for alarm. The toxic effects which any chemical can cause are a function of exposure and innate toxicity, i.e. of the ability to reach in sufficient quantity a site where a biological process can be disrupted and of the tendency to cause disruption when it gets there. The processes by which chemicals reach sites of toxic action are the subject of this book, and are a fundamental consideration in ecotoxi cology. When a chemical enters the environment e.g. via a spillage or in an effluent, it is potentially subject to a wide variety of processes which may eliminate it from the environment completely, modify it into a more or less harmful substance, or transfer it to another part of the environment. The processes involved are complex and highly variable, but it is essential to increase our understanding of them.

This section also contains an extensive background of environmental legislation in the USA and within the European Community, and an introduction to hazard/risk assessment with case studies.
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
