Bringing new understanding to the sorption and transport of heavy metals in soils and aquifers, this book explores the sorption and mobility of single versus multiple heavy metals species in the vadose zone. It relates transport mechanisms to processes that govern the sorption mechanisms dominating in a competitive system of multiple heavy metal species. Edited by H. Magdi Selim, and featuring expert contributors, the book presents new experimental evidence and field results. This comprehensive work helps scientists identify competitive transport processes to better predict the potential mobility of multiple heavy metals in soils.
