Informationen zum Autor Edward Tipping works at the Natural Environment Research Council Centre for Ecology and Hydrology in Cumbria, England, and is a Visiting Professor at the University of Lancaster. After receiving his PhD from the University of Manchester in 1973, he spent five years at the Middlesex Hospital Medical School researching cancer biochemistry. He has spent short periods in laboratories in Finland, Sweden, the USA, Norway and the Netherlands, and published over 120 papers in international journals. Klappentext This book focuses on the important binding properties of these compounds which regulate the chemical reactivity and bioavailability of hydrogen and metal ions in the natural environment. Topics covered include the physico-chemical properties of humic matter and interactions of protons and metal cations with weak acids and macromolecules. Experimental laboratory methods are also discussed! together with mathematical modelling. Finally the author looks at how the results of this research can be used to interpret environmental phenomena in soils! waters and sediments. Zusammenfassung The first comprehensive account of these important environmental interactions! this book describes the binding reactions! how they can be mathematically modelled! and how this knowledge is used to interpret environmental phenomena in soils! waters and sediments. A valuable resource for advanced undergraduate and graduate students! environmental scientists! ecologists and geochemists. Inhaltsverzeichnis 1. Introduction; 2.
