H. Magdi Selim is professor of soil physics, A. George and Mildred L. Caldwell Endowed Professor, School of Plant, Environmental and Soil Science at Louisiana State University at Baton Rouge. He is internationally recognized for his research in the areas of kinetics of reactive chemicals in heterogeneous porous media and transport modeling of dissolved chemicals in water-saturated and unsaturated soils. Dr. Selim is the original developer of the two-site and second-order models for describing the retention processes of dissolved chemicals in soils and natural materials in porous media. Pioneering works also include multistep/multireaction and nonlinear kinetic models for heavy metals, radionuclides, explosive contaminants, and phosphorus and pesticides in soils and subsurface media. His research interests include saturated and unsaturated water flow in multilayered one- and two-dimensional systems.

Most reported incidents of soil contamination include an array of heavy metals species rather than a single ion. The various interactions in these multicomponent or multiple-ion systems significantly impact the fate and transport of heavy metals, and competition for sorption sites on soil matrix surfaces is a common phenomenon. Because of this, con
