Refractory Organic Substances in the Environment

Hardcover  XXXIII, 546 Pages  ISBN 3527301739      £130.00

Results of six years of cutting-edge research on refractory organic substances (ROS), also known as humic substances or natural organic matter, are presented in this book. It offers comprehensive coverage of the structures, the behaviour and the interactions of this class of compounds with respect to our environment, including both chemical and biological aspects. As refractory organic substances are important for agriculture, water supply, and environmental protection, this book will be of interest for researchers and professionals active in these fields.
