Biophysico-Chemical Processes of Heavy Metals and Metalloids in Soil Environments

The objective of this project is to produce a reference providing the scientific community with a critical evaluation of the biophysico-chemical processes of metals and metalloids in soil environments. The evaluation, which is being conducted by a multidisciplinary group of soil and environmental scientists, will cover interactions with soil components (clay minerals, organics, microorganisms) as well as their speciation, mobility, bioavailability, and toxicity. It will also examine innovative restoration strategies for polluted soils.

The behavior of heavy metals and metalloids depends on chemical, physico-chemical, and biological factors associated with microbial activities. Dynamics and equilibria of these elements in soil environments are significantly influenced by structural, surface, and solution chemistry of soils and interactions of soil minerals with organic components and microorganisms. These physicochemical-biological interactions would influence the transfer of these elements from the inorganic and organic soil constituents to the soil solution and to plants.

Biogeochemical processes operating in soil environments that affect the fate, behavior, and bioavailability of metals and metalloids is currently an area of active research. Yet, a comprehensive and detailed book describing the current state of knowledge on the subject is absent from scientific literature. This book will bring a critical, qualitative and quantitative review of the fundamentals of the physics and chemistry of heavy-metal and metalloid interactions in soils, including the influence of soil microorganisms on these processes. In addition, the book will review the latest advances in spectroscopy and how they can be used to study various aspects of heavy-metal and metalloid interactions with inorganic and organic components.

The book will be co-edited by A. Violante, P.M. Huang, and G.M. Gadd.
