Chemical Processes in Marine Environments

This book discusses recent developments in the study of chemical processes and equilibria in the marine environment and in the air/water and water/sediment interfaces. The chemical cycle of carbon as well as the effect of organic substances on the speciation and distribution of inorganic and organometallic substances are extensively discussed. Much of the recent progress in the area is the direct result of advanced analytical technologies and chemometric applications which are highlighted in the book.
