Bio-Geo Interactions in Metal-Contaminated Soils

Metal contamination is an increasing eco-toxicological risk. Understanding the processes involved in metal mobilization, sorption and mineralization in soils is vital for effective soil bioremediation, and this volume covers current concepts and methods.

Metal contamination is an increasing ecological and eco-toxicological risk. Understanding the processes involved in metal mobilization, sorption and mineralization in soils are key features for soil bioremediation.Following an introduction to the physical, chemical and biological components of contaminated soils, various chapters address the interactions of soil, microorganisms, plants and the water phase necessary to transfer metals into biological systems. These include topics such as potential hazards at mining sites; rare earth elements in biotic and abiotic acidic systems; manganese redox reactions; biomineralisation, uranium in seepage water; metal-resistant streptomycetes; mycorrhiza in re-forestation; metal (hyper)accummulation in plants; microbial metal uptake; and their potential for bioremediation.This book will be of interest to soil biologists, geologists and chemists, researchers and graduate students, as well as consulting companies and small enterprises involved in bioremediation.

Provides an overview of the current concepts Includes tools for soil remediation A valuable source of information for scientists in soil ecology, environmental sciences, microbiology, plant physiology and biogeosciences Includes supplementary material: sn.pub/extras
