Synopses & Reviews
Phosphate and nitrogen compounds control growth of vegetation in most, if not all, fresh, brackish or salt waters. This book deals with the processes constituting the cycles of the phosphate and nitrogen compounds in sediment and the phosphate equilibria between the sediment and the overlying water. Sediment, to a large extent, controls the P- and N concentrations and thus primary production. In most waters, too high concentrations of these compounds cause excessive growth of algae, causing so-called eutrophication. Abatement of this can only be achieved after a complete understanding of the quantitative role of sediment in the P- and N cycle.Thus, for the phosphate cycle the following processes are evaluated: P-binding onto sediments, viz., onto iron hydroxide and calcium carbonate (limestone), Fractionation of phosphate in relation to its bioavailability, Release processes under anoxic and oxic conditions, and their dependence on pH changes, Further items taken into account, including the influence of drying of sediment and its resuspension by wind. For the nitrogen cycle, the following are discussed: Ammonification of organically bound nitrogen, Nitrification and denitrification, including Dissimilatory Nitrate Reduction, Links with other chemical elements are made.Audience: This book will be of interest to students of limnology at graduate or Ph.D. levels, environmental engineers, biologists and chemists appointed to include sediment in their work or studies, and for water managers dealing with water quality control. The book should be seen as a complement to textbooks on limnology, in that it provides an in-depth treatment of the subject.
Review
From the reviews: "This book is essential reading to anyone interested in lake nutrient dynamics, or in the palaeoenvironmental interpretation of sediment chemistry. ... I can recommend this book as a useful text for anyone with an interest in general palaeolimnology, providing a thorough review of current practical knowledge about nutrient dynamics in lakes, and how this ties in with sediment composition. It is also valuable reading to anyone starting out to study lake sediment chemistry ... ." (John Boyle, Journal of Paleolimnology, Vol. 38, 2007)

Synopsis
This book deals with the processes behind cycles of the phosphate and nitrogen compounds in sediment and the phosphate equilibria between the sediment and the overlying water. In most waters, excessive concentrations of these compounds causes eutrophication: rapid, choking growth of algae. The chapters of this book probe the chemicals involved in considerable detail, and offer the complete understanding needed to remediate or prevent pollution problems.
