Present in soil and water, humic substances are the most widespread organic compounds, naturally occurring from a physical, chemical, and microbiological transformation of biomolecules. They represent about 25% of the total organic carbon on the Earth and comprise up to 75% of the dissolved organic carbon in water, making them important for multiple environmental processes in both soil and aquatic systems. Despite many decades of extensive study, the formation mechanisms of humic substances are still a subject of discussion and controversy. This book examines the dynamics of humic substances, their physicochemical and biological properties, and methods for their extraction and characterization. The book also sheds light on recent advances and applications of humic substances in agriculture, environment, industry, and medicine.

Humic substances are ubiquitous in the environment. These remarkable brown biomaterials are found in animals, plants, coals, sediments, soils and water. They are crucial components of the carbon cycle and other life processes. Humic Substances: Nature's Most Versatile Materials contains a compilation of papers presented at the 2002 Humic Substances Seminar and will keep humic substances scientists up to date with the latest research.

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).

This publication is one of the series of IAEA publications on the environmental behaviour of naturally occurring radionuclides. It outlines uranium behaviour in different environments, as well as its transfer to, and metabolism in, humans. The publication also provides concepts, models and data required for the assessment of the impacts of uranium on non-human biota. Assessing the environmental and health effects of uranium poses specific challenges because of the combination of different types of hazard and potential exposures. Therefore, both the radiotoxicity and chemical toxicity of uranium are considered in this publication.

This book on biopolymers offers a comprehensive source for biomaterial professionals. It covers all elementary topics related to the properties of biopolymers, the production, and processing of biopolymers, applications of biopolymers, examples of biopolymers, and the future of biopolymers. Edited by experts in the field, the book highlights international professionals’ longstanding experiences and addresses the requirements of practitioners and newcomers in this field in finding a solution to their problems. The book brings together several natural polymers, their extraction/production, and physio-chemical features. The topics covered in this book are biopolymers from renewable sources, marine prokaryotes, soy protein and humus oils, biopolymer recycling, chemical modifications, and specific properties. The book also focuses on the potential and diverse applications of biogenic and bio-derived polymers. The content includes industrial applications of natural polymeric molecules and applications in key areas such as material, biomedical, sensing, packaging, biomedicine, and biotechnology, and tissue engineering applications are discussed in detail. The objective of this book is to fill the gap between the researchers working in the laboratory to cutting-edge technological applications in related industries. This book will be a very valuable reference material for graduates and post-graduate students, academic researchers, professionals, research scholars, and scientists, and for anyone who has a flavor for doing biomaterial research. The books are designed to serve as a bridge between undergraduate textbooks in biochemistry and professional literature. The book provides universal perspectives for an emerging field where classical polymer science blends with molecular biology with highlights on recent advances.

The Ion Exchange and Solvent Extraction series treats ion exchange and solvent extraction both as discrete topics and as a unified, multidisciplinary study - presenting new insights for researchers in many chemical and related field. Containing current knowledge and results in ion exchange, this text: presents an overview of the chemical thermodynamics of cation-exchange reactions, with particular emphasis placed on liquid-phase- and solid-phase-activity coefficient models; describes the development of surface complexation theory and its application to the ion exchange phenomenon; discusses metal-natural colloid surface reactions and their consideration by surface complexation modelling complements; and covers the influence of humic substances on the uptake of metal ions by naturally occurring materials.
