Humic Substances, Peats and Sludges
Based on the contributions given at a leading international conference, this volume concentrates on developments in the environmentally-friendly disposal of sludges and on the reawakened interest in composting which has emerged as a result of significant European directives.
Humic Substances
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.
Advances in Carbohydrate Chemistry and Biochemistry
Since its inception in 1945, this serial has provided critical and integrating articles written by research specialists in industrial, analytical, and technological aspects of biochemistry, organic chemistry, and instrumentation methodology in the study of carbohydrates. The articles provide a definitive interpretation of the current status and future trends in carbohydrate chemistry and biochemistry.

Humic Substances
"Humic substances may not be beautiful, but they do beautiful things." Furthermore, these richly carbon-endowed polymers are among nature's least understood materials. Twenty papers from the second Humic Substances [HSs] Seminar held March 27, 1998 at Northeastern U., Boston, delve into the multiple roles of HSs as acid-base buffers; binders to metals, molecules, ions, clay, and other polymers; water retainers (in the solid state); and catalysts and regulators in all life forms. Topics include: progress toward characterizing the properties of HSs, humic and fulvic acids in litter decomposition and composting, the implications for biological activity of the generation of free radicals by humic acid, HSs for enhancing turfgrass growth, and the humic acid solution to the greenhouse gas dilemma.

Interactions at the Soil Colloid
About 20 years ago the emphasis in soil chemistry research switched from studies of problems related to scarcities of plant nutrients to those arising from soil pollutants. The new problems have come about because of the excessive uses of fertilizers, the inputs from farm and industrial wastes, the widespread applications of anthropogenie xenobiotic chemicals, and the deterioration of soil structure resulting from certain modern agriculture practises. The International Society of Soil Science (ISSS) recognized these problems and challenges. A provisional Working Group was set up in 1978 to focus attention on soil colloids with a view to understanding better the interactions wh ich take place...
Heavy Metals Release in Soils
Understanding the mechanisms associated with metal complexes and the sequestering metal contaminants in the environment is essential for effective remediation. Heavy Metal Release in Soils describes and quantifies desorption/release kinetics and dissolution reactions in the release of heavy metals from soil. The book focuses on: New techniques - microscopic surface techniques, NMR and electrophoresis, XAFS, SFM, and time-resolved ATR-FTIR Theoretical analysis and kinetic approaches - adsorption/desorption hysteresis, competitive sorption and transport, multi-component models, speciation kinetics, isotherms and soil and metal parameters, and the role of soil properties on transport Applicatio...
Soil Colloids and Their Associations in Aggregates
S. Henin Versailles, France It was a pleasure for me to take part in the NATO Advanced Study Workshop for studies of 'Soil Colloids and their Associations in Soil Aggregates'. The meeting provided me with a welcome opportunity to renew acquaintances with respected colleagues in the various fields of Soil Science, to listen to their presentations, and be involved in discussions which were at the frontiers of the science which deals with the structures and the associations of the soil colloidal constituents. In my view the rapid advances in Soil Science, and the great benefits to agriculture from these, have their origins in the emerging understanding of the structures and the associations of ...
Organic Substances in Soil and Water
Organic Substances in Soil and Water documents the latest research in the subject and reviews the function, properties and structure of organic substances in influencing (and frequently dominating) the behaviour and fate of chemical contaminants in soil, surface water and groundwater systems. The book presents 'state-of-the-art' contributions from leading authorities on the nature of solid and dissolved phase organic substances, their interactions with organic and inorganic chemicals, and the implications of these interactions for agriculture and environmental pollution. It considers recent advances, highlights unresolved problems, and makes suggestions for the direction of future research. Organic Substances in Soil and Water gives a truly international perspective with contributions from four continents and makes important reading for graduates and researchers in environmental and agricultural chemistry, pollution, and surface and colloid science.
