Water is essential for life, a strategic resource for every country and population. Its availability and sanitary safety is highly connected with the health and economy status of population. Burden of disease due to polluted water is a major public health problem throughout the world. Many pollutants in water streams have been identified as toxic and harmful to the environment and human health, and among them arsenic, mercury and cadmium are considered as high priority ones. Providing population with safe drinking water became the priority and at the same time a big challenge for the modern society. Many funding agencies in various countries have assigned a high priority to the envir- mental security and pollution prevention. UN, being one of them, launched the “International Decade for Action: Water for life 2005–2015. ” Therefore, today’s political and social climate presents an important opportunity to implement principles of sustainable development and to preserve resources essential for future life. This process requires interdisciplinary approach; it is critically important to stimulate interactions between medical doctors, chemists, physicist, materials scientists, engineers and policy makers, which are already experienced in their specific areas. It is also our ethical obligation to preserve existing water resources and existing eco systems enhancing their biodiversity. The NATO Advanced Research Workshop “Water Treatment Te- nologies for the Removal of High-Toxicity Pollutants” took place on September 13–17, 2008 in Košice, Slovak Republic.

In contrast to the classical books which largely focus on separate, individual physicochemical and biological aspects, this book aims to integrate the frontiers of knowledge on the fundamentals and the impact of physicochemical and biological interactions and processes of AOCs in soil, sediment, water and air. The specific objectives of this book are to address: (1) fundamental biophysico-chemical processes of AOCs in the environment, (2) occurrence and distribution of AOCs in air, water, and soil, and their global cycling, (3) the state-of-the-art analytical techniques of AOCs, and (4) restoration of natural environments contaminated by AOCs. The book also identifies the gaps in knowledge on the subject matter and as such provides future directions to stimulate scientific research to advance the chemical science on biophysico-chemical interfacial reactions in natural habitats. By virtue of complex nature of the interactions of AOCs with different environmental components and matrixes, no single available technique and instrument is satisfactory yet for determining their fate, transport, availability, and risk in the environment. In order to fully understand the biophysico-chemical interactions and processes of AOCs in the environment, it is critical to know chemical, physical and biological properties of AOCs and their analytical techniques. The book is unique because of its multidisciplinary approach as it provides a comprehensive and integrated coverage of biophysico-chemical reactions and processes of AOCs in various environments, associated analytical techniques, and restoration of natural environments contaminated by AOCs.

In the rhizosphere, exudates from plants and microorganisms as well as stable soil organic matter influence processes that can control plant growth, microbial infections, and nutrient uptake. As the chemistry and biochemistry of these substances becomes more and more clear, their study promises to shed light on the complex interactions between plant and soil microflora. Maintaining the interdisciplinary approach of the first edition, The Rhizosphere: Biochemistry and Organic Substances at the Soil-Plant Interface, Second Edition summarizes information on soil science, agronomy, plant nutrition, plant physiology, microbiology, and biochemistry to provide a comprehensive and updated overview of the most recent advances in the field. Revised and expanded, the second edition presents new information on areas that are only recently gaining importance for understanding the complex biochemistry of the soil-microbe-plant interaction. New topics include the role of nutrient availability in regulating root morphology and architecture, the involvement of root membrane activities in determining and responding to the nutritional conditions in the rhizosphere, molecular signals between root-root and root-microbe, and gene flow and the evolution of rhizosphere organisms and their coevolution with plants. The book also covers mathematical modeling and methodological approaches to the study of the rhizosphere. Information in all chapters derives from a molecular approach which contributes to a better understanding of the biochemical processes occurring at the plant-soil interface. Drawing on the expertise of pioneers in the field, The Rhizosphere: Biochemistry and Organic Substances at the Soil-Plant Interface, Second Edition contributes to the vigorous interchange between rhizosphere biochemistry and molecular biology to provide the most current information and stimulate further interest and research on this fascinating topic.

Pesticides are essential tools for crop protection and disease prevention. These agricultural chemicals (and their associated uses) continue to be subject to increased regulatory scrutiny, even though modern pesticides have become safer, more effective, and target specific. Pesticide persistence, off-target movement to ground and surface water systems, and potential for impacting non-target organisms are the major focus for regulatory assessments. Sorption and degradation are among the dominant processes that determine the fate and ecological risk of pesticides in the environment. Non-First Order Degradation and Time-Dependent Sorption of Organic Chemicals in Soil addresses pesticide sorption and degradation processes in the context of regulatory evaluation, yet with a special focus on the chemistry-soil-environment interactions to better quantify the increasingly observed non-first-order and time-despondent behavior in the environmental fate studies. Offering key insights from leading experts in the field, this volume will be a valuable resource for professionals and scholars involved in pesticide research.
