Discusses the major elements of the geochemical cycles and global fluxes found in the atmosphere, land, lakes, rivers, biota, and oceans, as well as the human effects on these fluxes. This book offers presentation of major advances in the study of chemical weathering. It provides global coverage of environmental problems involving water. "This well-written book is easy to read. It goes into just the right amount of detail; with the exception of trace elements! The authors have presented wide-ranging references providing the interested readers with more details for further investigation. The authors have followed a multidisciplinary approach in the whole book which makes it beneficial for students who major in Environmental Earth Sciences, Geology, Geochemistry, Biogeochemistry and the associated fields. Besides, this book is of reference value for researchers and graduate students."---Armaghan Attar, International Journal of Environmental Studies
