Effective remediation of polluted environments is a priority in both Eastern and Western countries. In the U.S. and Europe, remediation costs generally exceed the net economic value of the land. As a result, scientists and engineers on both sides of the Atlantic have aggressively tried to develop novel technologies to meet regulatory standards at a fraction of the costs. In situ remediation shows considerable promise from both technical and economic perspectives. In situ technologies that deploy natural attenuating agents such as humic substances (HS) may be even more cost effective. Numerous studies have shown humics capable of altering both the chemical and the physical speciation of the ecotoxicants and in turn attenuate potential adverse environmental repercussions. Furthermore, the reserves of inexpensive humic materials are immense. Which suggests HS portend great promise as inexpensive amendments to mitigate the environmental impacts of ecotoxicants and as active agents in remediation. To elucidate emerging concepts of humics-based remediation technologies, we organized the NATO Advanced Research Workshop (ARW), entitled "Use of humates to remediate polluted environments: from theory to practice", held on September 23-29, 2002 in Zvenigorod, Russia (see the web-site http://www.mgumus.chem.msu.ru/arw).

The field of humic matter research has undergone drastic changes in concepts and principles since the first edition of Humic Matter in Soil and the Environment: Principles and Controversies was published more than a decade ago. Still the only book of its kind specifically addressing humic acid principles and controversies, the Second Edition presents the newest advances in humic acid science. Eleven new and rewritten chapters replace the original nine, with updated material representing modern humic acid chemistry. This includes the delineation of organic matter, humus, and humic matter. The book begins by considering organic matter as a whole, describing terrestrial and aquatic organic matter. It examines humus as a mixture of humified and nonhumified organic matter, focusing also on the importance of the nonhumified fraction—plant biopolymers in their original or slightly decomposed forms—as raw materials for formation of the humic fraction. The book then presents concepts of humic matter, referred to as humic acid, covering a range of ideas from traditional views of biopolymers to the latest concepts based on micellar, supramolecular, and nanotube chemistry. The author presents the major pathways of humification and discusses humification theories. He also examines the extraction, isolation, and fractionation of humic matter. The book reviews the chemical composition and model structures of humic acids, the chemical and spectroscopic characterization of humic substances, and the electrochemical properties of humic matter. It also addresses the agronomic, environmental, and industrial (including pharmaceutical) importance of humic matter. This revised and updated edition continues the tradition of providing comprehensive coverage of the genesis, extraction, properties, and impacts of humic matter.

Here is a cohesive compilation of recent research results into the many aspects of water purification. Major sections cover the characterization and environmental impact of aquatic humic substances, their reactions in natural water and sediments, and their influences on water treatment. Topics examined include hazardous waste chemicals, water solubility enhancement, sorption, metal speciation, and photochemistry. Specific types of treatment processes are also described.

ISBN : 163482413X
This book is about humic and fulvic acids, two types of organic substances which are increasingly becoming popular in agriculture and organic farming. In this book, the authors study and reveal their research on humic substances and the different aspects related to their formation. Other chapters include recent research on GRSP (Glomalin Related Soil Protein) and its relation to different kinds of fluorescent substances, including fulvic acid-like and humic acid-like substances. The last two chapters of the book explore humic acids and their ability to interfere in molecular ecological studies as well as the various methods one could use to measure the humic acids' concentration in soil-extracted nucleic acids. Finally, this book presents an in-depth look at the role of humic materials in the dispersion of radioactive contaminants in the environment, the latter of which are some of the most broadly circulated substances on the earth's surface, occurring in soils, rivers, lakes and seas.

This is the first book aimed at the development of a common language among scientists working in the field of humic research and environmental engineers specialized in remediation technologies. In pursuing this goal, the engineer is provided with sufficient information on the basics and state of the art of humic research pertinent to remediation. For the interested scientist, this text provides sufficient information on the methods, needs, and limitations of existing remediation technologies, and on the latest developments in applied humic research. A novel approach is undertaken to categorizing the interactions encountered between humics, ecotoxicants, and living organisms in a polluted environment in the context of remediation chemistry. The volume pays particular attention to in situ remediation as the most viable option for the application of humics. The content of this book is of interest to scientists and engineers.

Humic substances are everywhere; in plants, soils and water. These brown materials are the most versatile and widely dispersed organic compounds on Earth. Studies of humic substances sustain all current efforts to bioremediate and purify water, develop and support sustainable agriculture, decontaminate polluted soil, and combat soul desertification and erosion. Taken from the 2004 Humic Substances Seminar VII held at Northeastern University, this selection of expert papers investigate the important functions of humic substances, focusing on water treatment and land preservation. Reflecting the work of an international host of scientists, this book describes how researchers from many disciplines are working to link humic substances structures to their many crucial functions in land and water conservation. Reporting on the latest analytical advances and information for understanding humic substances, this book will be of great interest to a wide range of readers from graduate students and professional biologists to soil scientists and engineers.
