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.

Available in PDF, EPUB and Kindle. Book excerpt: Heavy Metals in the Aquatic Environment contains the proceedings of an international conference held in Nashville, Tennessee in December 1973. This conference is co-sponsored by the International Association on Water Pollution Research, the Sport Fishing Institute, the American Fishing Tackle Manufacturers Association, and Vanderbilt University's Department of Environmental and Water Resources Engineering. Contributors focus on the hazards posed by heavy metals present in the aquatic environment and how to control them. This text consists of 45 chapters divided into eight sections. This book assesses the environmental impact of heavy metals found in the aquatic environment; the economic impact of removing them from waste effluents; and the costs vs. benefits attained by their removal. The social costs are also evaluated. After an introduction to dose-response relationships resulting from human exposure to methylmercury compounds, the discussion turns to the toxicity of cadmium in relation to itai-itai disease; the effects of heavy metals on fish and aquatic organisms; and the analytical methods used for measuring concentrations of methylmercury and other heavy metals. The next sections explore the transport, distribution, and removal of heavy metals, along with regulations, standards, surveillance, and monitoring aimed at addressing the problem. This book will be of interest to planners and policymakers involved in water pollution control.

This book was released on 2012-12-06 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of the European Community in developing environmental legislation has focused the minds of pollution control agencies and industrialists on the need for, and the evidence to support, water quality standards. This is particularly so for the Dangerous Substances Directive which has led to European standards for cadmium, mercury and lindane. Additionally the United Kingdom has published standards for six other non-ferrous metals. In this book I have sought to review the aquatic toxicity information for these and other metals, not just by the collation of the results of all the published toxicity tests, but by the critical consideration of the test techniques. A surprising proportion of the reported toxicity studies for aquatic organisms are based on unsatisfactory chemical or biological methods. That such weaknesses persist at a time of limited resources for environmental research is disappointing, especially when sound metho dologies are extensively documented and widely published. Evaluation of the critically reviewed and vetted data indicates that many of the previously accepted generalisations about the toxicity of metals to aquatic life are invalid: for instance the assumption that salmonid species of fish are more susceptible to these metals than coarse fish, or that increased water hardness decreases toxicity. Too few studies have actually sought to test such hypotheses.

Download or read book Fresh Water Pollution Dynamics and Remediation written by Humaira Qadri and published by Springer. This book was released on 2019-07-17 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater is a finite resource and is being deteriorated directly and indirectly by anthropogenic pressures. Preserving the quality and availability of freshwater resources is becoming one of the most pressing environmental challenges on the international horizon. To ensure the preservation as well as availability of freshwater resources, there is a need to understand the ecology of the freshwater systems, pollution problems, their impacts, restoration techniques to be opted and the conservation measures. In this backdrop the present book on ‘Freshwater Pollution Dynamics and Remediation’ has been compiled. The book provides an understanding about the present state of art, pollution impacts including the changes in the environmental quality as well as the shift in the aquatic biological communities of the fragile freshwater ecosystems. Besides, the impact of deteriorating quality of the freshwater ecosystems on the animal and human health is also discussed in detail. This book provides a comprehensive account of the techniques based on updated research in biotechnology, bio-remediation, phyto-remediation and nano-bioremediation. The role of biosorpers and biofilms as a remediation tool has also been detailed. The book is a ready reference for researchers, scientists and educators who are involved in the freshwater pollution, remediation and management studies. The book editors with an expertise in diverse research fields in freshwater ecosystems have congregated the most inclusive research accounts on the freshwater pollution and remediation and thus developed a repository of diverse knowledge on the subject

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this volume is to draw together state-of-the-art reviews of knowledge onlevels of heavy metals in marine environments (particularly in marine animals), the dynamicprocesses in these systems, toxic effects, and threats presented by heavy metals in foods ofmarine origin.All heavy metals, whether biologically essential or not, have the potential to be toxicto organisms at a threshold bioavailability. Such threshold concentrations vary betweenmetals, between species and with the physicochemical characteristics of the medium, somelike copper being particularly toxic even though essential in trace amounts. Responses ofanimals to metals in their medium or food depend to a large extent on the ability of speciesto regulate levels attained in their tissues. Higher animals have the capacity to regulate levelsof many metals, while marine invertebrates can regulate some within certain limits. Whereanimals cannot regulate physiological levels of metals, an alternative strategy is to detoxifyand store metals in relatively harmless forms. Knowledge of the manner in which animals deal with potentially toxic concentrations of heavy metals is of fundamental importance in the assessment of metal pollution by analysis of metal levels in biological samples. The interaction of heavy metals with biological materials is a key theme running through this volume. Toxic effects may be reflected at the individual, population, or ecosystem level, affecting species composition and production levels, or may be of direct dietary significance to man. The global cycling of metals through the marine environment is crucially affected by biological processes.
Download or read book Impact of Heavy Metals on the Environment written by Jean-Pierre Vernet and published by Elsevier Publishing Company. This book was released on 1992 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Highlighted in this compilation of papers is the role and importance of heavy metals in the environment. It provides up-to-date information in a field of active research and progress, where the focus is on effects and interactions between the environment and organisms, as well as contaminant dynamics. Several papers address the impact of heavy metals on our health. The influence of metals on plants is described in an exhaustive study on lichens, which have been widely used as biomonitors for environmental contamination by heavy metals. Metals are also accumulated by animals, as seen in a chapter which focusses on sediment/benthic organism interactions and biomonitoring in fish. Soil interactions are discussed, as well as regional studies of freshwater sediments and the marine environment. The final part of the book addresses a crucial problem: the management of stabilized municipal waste sludges. As a result, the most important and significant recent trends are included, emphasizing interactions with and impacts of heavy metals on humans, animals, plants and soils.

Download or read book Heavy Metals in Natural Waters written by J.W. Moore and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: This series is dedicated to serving the growing community of scholars and practitioners concerned with the principles and applications of environ mental management. Each volume is a thorough treatment of a specific topic of importance for proper management practices. A fundamental objective of these books is to help the reader discern and implement man's stewardship of our environment and the world's renewable re sources. For we must strive to understand the relationship between man and nature, act to bring harmony to it, and nurture an environment that is both stable and productive. These objectives have often eluded us because the pursuit of other individual and societal goals has diverted us from a course of living in balance with the environment. At times, therefore, the environmental manager may have to exert restrictive control, which is usually best applied to man, not nature. Attempts to alter or harness nature have often failed or backfired, as exemplified by the results of imprudent use of herbicides, fertilizers, water, and other agents. Each book in this series will shed light on the fundamental and applied aspects of environmental management. It is hoped that each will help solve a practical and serious environmental problem.

Download or read book Ecological Quality Status of Marine Environment written by Gehan Mohamed El Zokm and published by Springer Nature. This book was released on 2023 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this one-of-a-kind book was to provide a critical and in-depth understanding of various AVS-SEM models as predictors for assessing the ecological impact of heavy metals (particularly dibasic cations; Zn, Cd, Ni, Cu, and Pb) on aquatic environments, including the theories underlying these models, descriptive equations, modes of action, methodology, efficiency, applicability, and statistical approaches, as well as comparison with other pollution assessment techniques in the aquatic environments. Metals in interstitial water can be reduced in sediments that co-precipitate with iron (Fe) and manganese (Mn) in FeS or MnS minerals, as well as replace them. This book outlines a system that can be used to track heavy metal contamination in countries with coastal regions that extend over water bodies that are subjected to pollution sources, such as the Mediterranean Basin countries. Moreover, this book will be of great interest to academics, professionals, practitioners, post-graduate students (M.Sc. and Ph.D.), and undergraduates because it gives a clear overview of heavy metal assessment for people interested in environmental studies focusing on the marine environment. It also provides decision-makers with a realistic perspective of the environmental file, allowing them to address environmental issues and directing stockholders to safer locations for environmental activity. From a future perspective, management is advised to overcome the difficulties within that technique, such as accurate handling procedures and different approaches to sampling onshore and offshore. Sequential leaching strategies, especially geochemical fractionation analysis, and knowledge of the interactions and significance of AVS in the marine sector, especially toxicity tests (bioassay) are recommended.

Available in PDF, EPUB and Kindle. Book excerpt: Many of the pollutants discharged into the sea are directly or indirectly the result of human activities. Some of these substances are biodegradable, while others are not. This study is devoted to monitoring areas of the environment. Methods assessment is based on monitoring data and an evaluation of the impact of pollution.Surveillance provides a scientific basis for standards development and application. The methodology of marine pollution control is governed by algorithms and models. A monitoring strategy should be put in place, coupled with an environmental assessment concept, through targeted research activities in areas identified at local and regional levels. This concept will make it possible to diagnose the state of "health" of these zones and consequently to correct any anomalies. Monitoring of the marine and coastal environment is based on recent methods and validated after experiments in the field of marine pollution.
