Trace Elements in Waterlogged Soils and Sediments

Jörg Rinklebe is a professor for soil and groundwater management at the University of Wuppertal (Germany). From 1997 to 2006, Dr. Rinklebe worked as a scientist and project leader at the department of soil sciences at the UFZ Centre for Environmental Research Leipzig-Halle, Germany. He studied ecology for one year at the University of Edinburgh, United Kingdom (1992–1993). He studied agriculture, specializing in soil science and plant nutrition, at the Martin Luther University of Halle-Wittenberg, Germany, and earned his PhD in soil science at the same university. Currently his research is mainly focused on wetland soils, sediments, waters, plants, and the related pollution (trace elements and nutrients) and biogeochemical issues. He also has a certain expertise in remediation of soils and soil microbiology. Professor Rinklebe is internationally recognized, particularly for his research in the area of the redox-chemistry of trace elements in flooded soils. He has published many scientific papers in international and national journals as well as numerous book chapters. He serves on several editorial boards (Geoderma, Water, Air, and Soil Pollution, Ecotoxicology, Archive of Agronomy and Soil Science). He is also a reviewer for many international journals. He has co-organized several special symposia at various international conferences, such as Biogeochemistry of Trace Elements (10th, 11th, 12th, and 13th ICOBTE) and International Conference on Heavy Metals in the Environment (15th, 16th, and 17th ICHMET). He has been an invited speaker at many international conferences.Anna Sophia Knox is a fellow scientist at the Savannah River National Laboratory (SRNL) in Aiken, South Carolina, where she conducts research on the remediation of contaminated sediments and soils and development of new materials for the stabilization of contaminants. She earned a PhD (1993) in agronomy and soil science and was certified as a

Wetland and other water-logged soils are of special importance in providing particular ecosystem services such as hydrological buffering, organic carbon storage, habitat and biodiversity source. Sediments play a role of similar importance as components of the aquatic environment at the bottom of water bodies. Both have in common that they also act as sinks for recalcitrant chemicals and as such are increasingly loaded with trace elements of anthropogenic origin. Due to the dominance of anaerobic conditions, the fate of trace elements in water-logged soils and sediments is governed by very different processes and mechanisms in these environments as compared to well-aerated soils. Against this backdrop, it is all the more remarkable how little we still know about these processes and the factors driving them. This book thus is very timely. It is also very comprehensive. In eighteen chapters written by experts in the respective fields, it gives the latest findings and insights into physicochemical factors and reactions controlling the speciation and binding of heavy metals and metalloids in water-logged soils and sediments, their bioavailability and the assessment of associated risks for humans and other recipients, and also on established remediation technology. Several chapters have a focus on redox-sensitive metals and metalloids such as arsenic, selenium, chromium and uranium. Some deal with new contaminants such as rare earth elements, others with ‘usual suspects’ such as cadmium and zinc. While various contributions are devoted to more fundamental aspects such as the kinetics of sorption and desorption processes or the mechanisms governing the retention and mobility of nanoparticles in aquatic environments, others provide insight into the role of particular environments such as paddies and other temporary flooded soils for trace element behavior or present specific case studies, e.g. on the fate of subsurface chromium on the Hanford site.
