Dynamics and Bioavailability of Heavy Metals in the Rootzone

by H. Magdi Selim (Editor)

Overview

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 Hea

About the Author

Dr. H Madgi Selim is professor of Soil Physics at Louisiana State University in Baton Rouge. Dr. Selim's research accomplishments have been in the areas of solute and water flow in unsaturated and saturated soils, water management of irrigation and drainage systems, spatial and temporal variability of soil physical properties, and chemical and physical processes governing the interactions and transport of solutes in the root zone. Selim's research emphasizes the role of slow heavy metals release and processes governing mechanism of heavy metals in the vadose zone.

What People are Saying About This

From the Publisher

This book provides a multidisciplinary approach with emphasis on geohydrology, plant and soil science, and environmental chemistry. The primary focus 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. ... 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 is a compilation of valuable information and provides a coherent presentation of recent advances in techniques, modeling, and dynamics and bioavailability of heavy metals in the root zone.
