The fate of heavy metals in the soil environment is important because they tend to be reactive, mobile, and highly toxic. Reactivity and Transport of Heavy Metals in Soils examines the sometimes complex interactions that occur between metals and the soil they occupy. This practical guide presents and explains heavy metal issues crucial to hazardous waste site cleanup, including the use and limitation of equilibrium models for describing metal transport in soils; laboratory methods of obtaining kinetic data, data analysis, and model evaluation and validation; retention reactions in soils, with emphasis on commonly observed behavior of heavy metals; second-order two-site modeling approaches with examples of Cr(VI) transport in soils; physical nonequilibrium approaches based on multi-region (mobile-immobile) concepts; multicomponent approaches focusing on competitive ion exchange and specific sorption mechanisms during transport.
