Humic substances, the remarkable brown biomaterials in animals, coals, plants, sediments, soils and waters, are crucial components of the carbon cycle and other life processes. Thus greater knowledge and understanding of these versatile materials is of great importance to the productivity, health and safety of the world's ecosystems, humans, land and water. Presenting the best and most recent research in this important area, this book focuses on the molecular and chemical aspects of humic substances, with sophisticated analytical, chemical and physical techniques providing vital information. Areas covered include spectroscopy, modelling, mobility, properties and analysis of humic substances. Humic Substances: Structures, Models and Functions will be welcomed by researchers and professionals in academia, industry and government agencies worldwide, particularly where the science of humic substances finds applications, such as environmental remediation and sustainable agriculture.

Humic substances occur in all kinds of aquatic systems, but are particularly important in northern, coniferous areas. They strongly modify the aquatic ecosystems and also constitute a major problem in the drinking water supply. This volume covers all aspects of aquatic humic substances, from their origin and chemical properties, their effects on light and nutrient regimes and biogeochemical cycling, to their role regarding organisms, productivity and food web organization from bacteria to fish. Special emphasis is paid to carbon cycling and food web organization in humic lakes, but aspects of marine carbon cycling related to humus are treated as well.

Adsorption of Metals by Geomedia, serves as a needed resource for this topic which has received much attention during the past 15 years. The book provides an in-depth review of the field, followed by numerouschapters that document the current status of adsorption research for a variety of metals by geomedia ranging from individual minerals to sediments and soils. Adsorption mechanisms are detailed and precipitation is presented as a distinct sorption process.Virtually all factors affecting the extent of metal adsorption are examined, including the effects of selected anions, competition among metals, pH, metal concentration, loading, variable metal adsorption capacity, ionic strength, hydrogen exchange and stoichiometry, and solids concentration. A variety of adsorption models are briefly presented and some are used to extend laboratory studies to field sites. The book is comprised of a collection of papers contributed by leading investigators from Canada, France, the Netherlands, the United Kingdom and the US. - Includes a wide-ranging review of the status of adsorption research and a prospectus on future research - Details all known factors affecting the extent of adsorption - Covers basic adsorption equations and interrelationships - Clearly documents experimental procedures - Presents adsorption data for eleven metals and three other elements - Uses normalization to greatly reduce apparent variability among absorbents - Provides extensive literature citations and a comprehensive index

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).

Many environmental processes are influenced, if not controlled, by microbial action and it is becoming increasingly important to develop an understanding of microbial roles in geochemistry. This book brings together state of the art research into microbiological processes and the extent to which they affect or can be used to control radioactive elements. The basic principles and fundamental mechanisms by which microbes and radionuclides interact are outlined, the methodology described, potential microbial influences on waste repositories examined, direct and indirect effects on transport both on local and global scales considered and potential technological applications identified.The book is directed towards advanced undergraduate students, postgraduates and researchers in the areas of environmental radioactivity, environmental microbiology, biotechnology and radioactive waste management. It will also be of interest to regulators, policy makers and non-governmental organisations.This novel and timely book offers a fully integrated approach to a topical international issue.
