Concerns regarding heavy metal contamination in terrestrial
ecosystems have prompted increasing efforts on limiting their
bioavailability in the root zone. The complexity of the hydrologic
system gives rise to the need for understanding the fate and
transport of trace elements in the soil-water-plant environment.
Dynamics and Bioavailability of Heavy Metals in the Rootzone
provides a multidisciplinary approach with emphasis on
geohydrology, plant and soil science, and environmental chemistry.
The primary focus of this book is on different approaches that
describe the dynamics of heavy metals in the soil system. These
approaches are key to providing direct information on the
concentration of heavy metals and hence on their transport,
toxicity, and bioavailability. The book includes chapters covering
equilibrium and kinetic models of heavy metal interactions as well
as non-equilibrium transport models. It also discusses chemical
processes controlling soil solution concentrations and modeling of
heavy metals adsorption. Addressing the biological component of
heavy metal dynamics, this work examines rhizosphere microorganisms
and phytoremediation. Colloid-associated transport, which can
result in groundwater contamination, is discussed in relation to
reclaimed mine sites. The authors also present an overview of
recent advancements in the biogeochemistry of trace elements and
their environmental implications. Additional chapters include
examination of various natural environments including runoff waters
at the watershed scale, heavy metal transformation in wetlands,
dynamics of trace metals in frequently flooded soils, and effects
on crops in biosolid-amended soils. Reliable assessment of
potential risks resulting from the transport of trace elements in
the soil environment requires the examination of complex chemical
and biological interactions due to the heterogeneous nature of
soils. This text describes the current state of the art in this
field and explores innovative experimental and theoretical/modeling
approaches that will enhance this knowledge. The book provides a
coherent presentation of recent advances in techniques, modeling,
and dynamics and bioavailability of heavy metals in the root zone.
