Book Description
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.

Book Description
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

Book Description
Presents papers from the August 1995 national meeting of the American Chemical Society, held in Chicago, IL. Contributions reflect recent advances in analytical methods and separation techniques for chemical characterization of humic and fulvic acids. After an overview section on the acids and organic colloidal materials in the environment, sections on molecular properties and sampling, metal binding, and organic pollutant interactions explore subjects including organic geochemistry and sources of natural aquatic forms; enhancement of the water solubility of organic pollutants by dissolved organic matter; and the role of humic substances and colloids in the behavior of radiotoxic elements in relation to nuclear waste disposal.

Book Description
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.

Book Description
Based on the Second International Conference of the International Humic Substances Society held in Birmingham, England, in 1984, this compendium reviews ways of studying the structure and function of humic substances, including the use of both degradative and nondegradative processes. Also considers nitrogen in humic substances, humic molecules and the interactions between humic and other substances.

Book Description
Over the past 50 years, triazines have made a great impact on agriculture and world hunger by assisting in the development of new farming methods, providing greater farming and land use capabilities, and increasing crop yields. Triazines are registered in over 80 countries and save billions of dollars a year. The Triazine Herbicides is the one book that presents a comprehensive view of the total science and agriculture of these chemicals. With emphasis on how the chemicals are studied and developed, reviewed, and used at the agricultural level this book provides valuable insight into the benefits of triazine herbicides for sustainable agriculture. - Presents previously unpublished information on the discovery, development and marketing of herbicides - Includes a vital section on the origin, use, economics and fate of triazine herbicides - Covers benefits of triazines in corn and sorghum, sugarcane, citrus, fruit and nut crops - Establishes best management practice and environmental benefits of use in conservation tillage

Book Description
Reporting on front-line research into these natural materials, this volume focuses on the use of chemical and physical methodology in seeking an explanation of the structures of humic substances (HSs) and their relation to their microscopic properties.

Book Description
For many years, the subject matter encompassed by the title of this book was largely limited to those who were interested in the two most economically important organic materials found buried in the Earth, namely, coal and petroleum. The point of view of any discussions which might occur, either in scientific meetings or in books that have been written, was, therefore, dominated largely by these interests. A great change has occurred in the last decade. This change had as its prime mover our growing knowledge of the molecular architecture of biological systems which, in turn, gave rise to a more legitimate asking of the question: "How did life come to be on the surface of the Earth?" A second motivation arose when the possibilities for the exploration of planets other than the Earth-the moon, Mars, and other parts of the solar system-became a reality. Thus the question of the possible existence of life elsewhere than on Earth conceivably could be answered.

Book Description
This volume uses a molecular approach to bring the reader up to date with research into the structure and properties of these unusual materials. Agricultural and environmental scientists will find its coverage of HS use for soil remediation and enhancement and in water purification as alternatives to conventional methods invaluable.
