Bringing new understanding to the sorption and transport of heavy metals in soils and aquifers, this book explores the sorption and mobility of single versus multiple heavy metals species in the vadose zone. It relates transport mechanisms to processes that govern the sorption mechanisms dominating in a competitive system of multiple heavy metal species. Edited by H. Magdi Selim, and featuring expert contributors, the book presents new experimental evidence and field results. This comprehensive work helps scientists identify competitive transport processes to better predict the potential mobility of multiple heavy metals in soils.

With contributions from pioneers in this area, this book covers state-of-the-art information on PRB technology. It details design criteria, predictive modeling, and application to contaminants beyond petroleum hydrocarbons, including inorganics and radionuclides.

Written by international experts in the field, this book supplies coherent presentations of recent developments along with a clear understanding of heavy metal dynamics and bioavailability in the soil root zone. It provides a multidisciplinary approach with emphasis on geohydrology, plant and soil science, and environmental chemistry. Evaluating the current state of the art in this field, the text explores innovative experimental and theoretical modeling approaches. Numerous figures, tables and equations are included within the text to further enhance knowledge of the subject.

This book provides the fundamentals for the understanding of reactive chemicals retention and their transport in soils and aquifers. The book offers the first comprehensive treatment with supporting examples of mathematical models that describe contaminants reactivity and transport in soils and aquifers. It is also a practical guide for designing experiments and collecting data that focuses on characterizing retention as well as release kinetic reactions in soils and contaminant transport experiments in the laboratory, greenhouse (column) and in the field.

Several studies have suggested varied interactions of heavy metals with phosphates in soils and the effects of phosphate on the bioavailability and mobility of heavy metals. Edited by one of the best specialists in soil science, this book focuses on the impact of phosphate on the fate of heavy metals in soils and heavy metals in the soil-water-plant as affected by phosphate. It features coverage of sorption and mobility influenced by the presence of phosphate in the vadose zone.

Many wetlands around the world act as sinks for pollutants, in particular for trace elements. In comparison to terrestrial environments, wetlands are still far less studied. A collaborative effort among world experts, this book brings the current knowledge concerning trace elements in temporary waterlogged soils and sediments together. It discusses factors controlling the dynamics and release kinetics of trace elements and their underlying biogeochemical processes. It also discusses current technologies for remediating sites contaminated with trace metals, and the role of bioavailability in risk assessment and regulatory decision making. This book is intended for professionals around the world in disciplines related to contaminant bioavailability in aquatic organisms, contaminant fate and transport, remediation technologies, and risk assessment of aquatic and wetland ecosystems.

Nickel (Ni), the fifth common element on the earth is widespread in the environment. Recently Ni has been proved essential for normal growth of many organisms, and at the same time Ni can become toxic to organisms when high in concentration. In several parts of the world, high Ni concentrations are causing serious environmental impacts. This book will be the first to discuss the problems related to Ni presence and raise the need for full investigation and more efforts to support this goal. It will present the recent advances in research on Ni nutrition of plants, Ni contamination of the environment--that is, soils, waters and plants--and methods of remediation.

Provides an overview of the entire nitrate cycle and the processes influencing nitrate transformation, and clearly identifies its role as an essential nutrient in plant growth, food preservation, and human health. It explains the discrepancies between public perceptions on nitrate harm versus the beneficial effects on human health.
