内容説明 In natural waters， trace elements - especially metals - may be present in different physicochemical forms varying in size， charge， and density. ?Trace Elements in Natural Waters? comprehensively covers the microchemical processes occurring in the water phase. This book describes geological and biological interactions involving supply or removal of trace elements in the water phase. Analytical aspects are included， since sampling， pre-analysis handling， and methods of analysis strongly influence the quality of data. Different natural water systems are reviewed with respect to sources， concentration levels， and physicochemical forms of trace elements. Also， important fields of future research are investigated.
