The occurrence of heavy metals in the environment, even in traces, represents a severe risk for the ecosystems and can be dangerous to human health. However, a better understanding of the main aspects involved is still needed to reduce its negative impact on the environment and health. This book covers the recent methods used for the evaluation of heavy metal pollution and the identification of its sources, descriptions of some of the processes involved in its mobility and transport, attempts to address health and environmental effects of heavy metals pollution, and presents alternative technologies for its removal and remediation from environmental samples. Therefore, this book is recommended for experts in the comprehensive management of metal contamination in different environmental compartments.

This volume discusses major areas of primary concern for the understanding of the complexity associated with ecological trace element research. These include sources and fates of trace elements; analytical techniques; and the distribution of trace elements in biota and soil and sediment reservoirs. Case studies, field work and laboratory studies intensively discussed in this volume are useful to enhance our knowledge about processes related to the biological response of trace metal stress under realistic environmental conditions.

This book focuses on the behavior and impact of trace metals in the environment by studying typical cases from China such as the Hetao Area of the Yellow River, Shanghai, and Nanjing. Based on samples and experiments on the behavior of pollutants, it systematically discusses the regulation of trace metals’ distribution, accumulation, and migration, associated with the cause of formation demonstration. The author subsequently uses the acquired data to review the evolving trend of trace metal behaviors in natural systems (river or lake water, sediments, and soils), develops suggestions for the prevention of their negative effects, and devise treatments. Moreover, he proposes solutions to difficult research issues such as trace metal speciation extraction, and an analysis, along with operational procedures. Given its scope, the book will provide a valuable guide for researchers and engineers in relevant disciplines of the environmental sciences and engineering, and for environmental policymakers to consult in practices.

Trace metals occur as natural constituents of the earth's crust, and are ever present constituents of soils, natural waters and living matter. The biological significance of this disparate assemblage of elements has gradually been uncovered during the twentieth century; the resultant picture is one of ever-increasing complexity. Several of these elements have been demonstrated to be essential to the functions of living organisms, others appear to only interact with living matter in a toxic manner, whilst an ever-decreasing number do not fall conveniently into either category. When the interactions between trace metals and plants are considered, one must take full account of the known chemical properties of each element. Consideration must be given to differences in chemical reactivity, solubility and to interactions with other inorganic and organic molecules. A clear understanding of the basic chemical properties of an element of interest is an essential pre-requisite to any subsequent consideration of its biological significance. Due consideration to basic chemical considerations is a theme which runs through the collection of chapters in both volumes.

Heavy Metals in the Environment: Impact, Assessment, and Remediation synthesizes both fundamental concepts of heavy metal pollutants and state-of-the-art techniques and technologies for assessment and remediation. The book discusses the sources, origin and health risk assessment of heavy metals as well as the application of GIS, remote sensing and multivariate techniques in the assessment of heavy metals. The various contamination indices like contamination factor, geoaccumulation index, enrichment factor, and pollution index ecological risk index are also included to provide further context on the state of heavy metals in the environment. Covering a variety of approaches, techniques, and scenarios, this book is a key resource for environmental scientists and policymakers working to address environmental pollutants. Covers state-of-the-art techniques for the assessment and remediation of heavy metals Presents the interdisciplinary impacts of heavy metals, including human health, ecosystems and water quality Includes various contamination indices, such as contamination factor, geoaccumulation index, enrichment factor, pollution index and ecological risk index

Fundamental Aspects of Pollution Control and Environmental Science 1: Trace-Element Contamination of the Environment investigates the global biological consequences of dispersal of trace elements that are mined from localized limited deposits in the environment. It considers the problem of trace-element contamination of the biosphere as an environmental pollution and as part of the ecological crisis as a whole. Comprised of eight chapters, this volume begins with an overview of trace-element contaminants, such as lead, cadmium, and mercury. It then discusses factors affecting the trace-element composition of soils, including sulfur, lime, and fertilizers. It explains as well the trace-element contamination of the atmosphere and hydrosphere, the sources of trace-element contamination of soils, and the availability of trace elements in the soil. The consequences of trace-element contamination of the soil, including its effects on crops and animals, are also discussed. The book also provides ways to prevent dispersal of metals in the environment. This book will be an essential reading for undergraduates, law students, and those who are interested about environmental pollution caused by trace elements.

This book presents in detail the state of knowledge of the distribution, bioavailability, biomagnification, discrimination, fate and sources of chemical pollutants (metals, metalloids, radionuclides and nutrients) in all compartments (atmosphere, water, deposits, biota) of the Baltic environment. Particular components of the Baltic ecosystem are considered as potential monitors of pollutants. Budgets of chemical elements and the ecological status of the Baltic Sea in the past, present and future are presented. Estimates of health risks to man in respect to some toxic metals and radionuclides in fish and seafood are briefly discussed. The content of the book makes possible the identification of gaps in our environmental knowledge of the Baltic Sea, with certain sections establishing possible priorities, key areas or strategies for future research.
