This volume presents work on HSs including instruments and techniques being developed to throw more light on their structure and relationship to macro- and micro-scopic properties.

DOWNLOAD EBOOK →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.

DOWNLOAD EBOOK →Humic Substances color all waters more or less brown. Their concentrations exceed all carbon of living organisms by at least one order of magnitude. Opposite to former paradigms, they participate in almost any metabolic pathway. They protect against UV-irradation, enable indirect photolysis and, thus, purify hazardous chemicals, they provide inorganic and organic nutrients, may form cryptic genes with DNA and dampen metabolic fluctuations. More recently they can increase adverse effects of hazardous chemicals and they can directly interfere with organisms. The book tries to relate effects to structural features.

DOWNLOAD EBOOK →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).

Wherever there is life on earth, there will also be ROS in the form of poorly biodegradable leftovers of organisms and as a source for new life. Furthermore, it is now beyond doubt that ROS are closely related to the carbon intensity identified as one of the driving forces in the dynamics of green house gas emission, such that ROS play a key role in sustainable development. 'Refractory Organic Substances in the Environment' provides the results of six years of top-priority research, funded by the Deutsche Forschungsgemeinschaft (DFG). This research program investigated the structure and function of ROS in different parts of the environment, from a chemical, physical, biological, and soil scientific point of view. It included the first systematic study of a set of reference samples from Central Europe, originating from a bog lake, soil seepage water, groundwater, and from the wastewaters of a brown coal processing plant and a secondary effluent. Thus, this work not only highlights the structural features obtained from the application of advanced analytical tools, but also the function in anthropogenically influenced aquatic systems and soils. Of special interest to students and researchers in life sciences.

DOWNLOAD EBOOK →Advances in Agronomy has the highest impact factor among serial publications in agriculture. The Science Citation Index, 1986, reports an impact factor over 2,459 and a cited half-life over 10 years. Volume 75 contains four outstanding reviews dealing with phytoremediation, issues related to water use in China, humic substances, and remote sensing. Chapter 1 is an extensive review on phytoremediation of metals, metalloids, and radionuclides, including discussion on phytoextraction technologies, hyperaccumulator plants, chemically induced phytoextraction, and phytovolatilization. Chapter 2 covers the conservation and use of water in Chinese agriculture including engineering, economic, and agronomic aspects and considerations. Chapter 3 presents advances in understanding the structure of humic substances, particularly the concept of a supramolecular structure. Analytical and molecular scale evidence for this latter structure are presented as well as discussions on the role of humic superstructures in soils. Chapter 4 presents frontiers in quantitative remote sensing of soil properties including principles, methods, mechanisms, and limitations.
