Book Description
Assessment, Restoration and Reclamation of Mining Influenced Soils covers processes operating in the environment as a result of mining activity, including the whole spectra of negative effects of anthropopressure and the environment, from changes in soil chemistry, changes in soil physical properties, geomechanical disturbances, and mine water discharges. Mining activity and its waste are an environmental concern. Knowledge of the fate of potentially harmful elements and their effect on plants and the food chain, and ultimately on human health, is still being understood. Therefore, there is a need for better knowledge on the origin, distribution, and management of mine waste on a global level. This book provides information on hazard assessment and remediation of the disturbed environment, including stabilization of contaminated soils and phytoremediation, and will help scientists and public authorities formulate answers to the daily challenges related to the restoration of contaminated land. - Provides a thorough overview of the processes operating on mining-devastated areas, as well as origin, distribution, and deactivation of harmful elements - Includes outcomes and recommendations of the Global Mining Initiative that are widely regarded as the code of conduct in the minerals industry - Contains global case studies that elucidate various aspects of assessment and restoration of mine-contaminated land

Book Description
This book presents a comprehensive and detailed description of remediation techniques for metal-contaminated soils derived from both natural processes and anthropogenic activities. Using a methodical, step-by-step presentation, the book starts by overviewing the origin of toxicants and the correlated comparative extent of contamination to the environment. The legal provisions as proposed or applied in different countries are then discussed to explain the global regulatory situation regarding soil contamination and the extent of consequent concern. The core part of this publication describes the major techniques for in situ or ex situ treatment of the contaminated soil to meet the regulatory limits. Finally, risk evaluation is incorporated, giving special attention to possible impacts during or after implementation of the remediation strategies. The intrusion of metals in soils mostly occurs from various anthropogenic activities, e.g., agricultural practices, industrial activities, and municipal waste disposal. The volumes of metal-contaminated soil are becoming greater than before and are ever-increasing due to rapid urbanization, intensified industrialization, and/or population booms in certain parts of the world. Hence, the options previously proposed, such as isolation of the contaminated site or movement of the contaminated mass to a secure disposal site after excavation, are becoming unsuitable from the economic point of view, and instead, decontamination alternatives are preferred. This book will help readers such as scientists and regulators to understand the details of the remediation techniques available to deal with the soils contaminated by toxic metals.

Book Description
While not all metals in Soil--plant systems are inherently toxic, particularly in low concentrations, there is an increasing incidence of metal pollution from aerial fallout, spoils, wastes and agricultural amendments including sewage sludge. Toxic Metals in Soil--Plant Systems discusses the processes of trace-metal cycling in contaminated ecosystems under conditions where their concentrations become toxic through high loading rates, long-term exposure or altered environmental conditions. Other environmental and pedological concentration mechanisms are discussed, including cation exchange and anion adsorption onto different soil materials. The book is divided into two sections; the first part discusses the sources and fates of metals in ecosystems, with an up-to-date review of the processes which control metal speciation in soils, metal uptake mechanisms, and plant responses to toxic metal concentrations in soils. A clear understanding of these processes and their interactions in soil is necessary before it is possible to instigate amelioration and restoration programmes for metal-contaminated land. In the second part of the book, a selection of case studies are presented which discuss metal toxicities and metal cycling in a range of different ecosystems, including managed agricultural systems, deciduous woodland, upland heather moorland, and tropical wetlands. In these studies a number of current issues are addressed, including the setting of toxicity thresholds for safe sewage sludge application to agricultural land, the accumulation of soil metals over time in aerially impacted systems, and metal transfers between ecosystem compartments, which are of particular concern in food crops. Providing an integrated view of toxic metals both in the soil and associated growing plants, this book covers a wide range of topics including agriculture, soil science, ecology and forestry and will be of use to researchers and environmental consultants working in these fields.

Book Description
Heavy metals can be emitted into environment by both natural and anthropogenic sources, mainly mining and industrial activity. Human exposure occurs through all environmental media. Infants are more susceptible to the adverse effects of exposure. Increasing attention is now being paid to the mental development of children exposed to heavy metals. The purpose of this book is to evaluate the existing knowledge on intellectual impairment in children exposed to heavy metals in their living environment and to identify the research needs in order to obtain a clearer picture of the situation in countries and regions at risk, in which the economy is closely related to metallurgy and heavy metals emission, and to recommend a strategy for human protection. In greater detail the main objectives could be formulated as follows: to review the principal sources of single, and complex mixtures of, heavy metal pollutants in the environment; to identify suitable methodology for chemical analyses in the environment and in humans; to evaluate the existing methods for measuring mental impairment, including their reliability and validity; to recommend a standard testing protocol to be used in future research; to assess the future role of environmental heavy metal pollution in countries and regions at risk and its effects on children’s neurological development; to recommend a prevention strategy for protecting children’s health and development.
