Chelating agents are in widespread use in technical and industrial applications. They are used extensively to control metal speciation in the pulp and paper industry, in photographical processes, in cooling waters, the oil industry, and in the nuclear industry. Further, they are incorporated into industrial and household cleaners, personal care products, and foodstuffs. As a result of such extensive use, anthropogenic chelating agents are ubiquitous in the environment. Due to their strong interactions with metals they have received considerable attention due to the potential for adverse effects on ecosystems and health. The goal of this book is to bring together researchers from a variety of disciplines - chemistry, environmental chemistry, soil chemistry, microbiology, phytoremediation, bioremediation, wastewater treatment, industry (pulp and paper, textile, oil production) - to present different aspects of the unique chemical properties of these compounds. This book describes the biogeochemistry of these important compounds, from their structure and speciation, through their behavior in natural systems, to their use in enhanced phytoremediation and their removal through biodegradation.

This Handbook discusses the recent advances in biodegradation technologies and highlights emerging sustainable materials, including environmentally friendly nano-based materials for replacing plastics. It is useful to scientists, engineers, biologists, medical doctors and provides alternative eco-friendly materials to replace the currently used ones with harmful impact on the environment and life. The chapters present different types of alternative materials in diverse areas, such as food packaging materials, materials for construction and agricultural materials. The principles and types of biodegration technologies are described in depth.

This book is aimed at generalizing the modern ideas of both biogeochemical and environmental risk assessment that have been developed in recent years. Only a few books are available in this interdisciplinary area, since most deal mainly with various technical aspects of ERA description and calculations. This text aims at supplementing the existing books by providing a modern understanding of mechanisms responsible for ecological risks for human beings and ecosystems.

Modern Biogeochemistry is aimed to generalize modern ideas of biogeochemical developments during the last decades. It is designed to support a general course in biogeochemistry, and as such, is likely to have a broad market among the many universities and colleges that are adding such courses to their curricula. This book aims to supplement the existing textbooks by providing modern understanding of biogeochemistry, from evolutionary biogeochemistry to practical applications of biogeochemical ideas such as human biogeochemistry, biogeochemical standards and biogeochemical technologies. To a certain extent this textbook is a summary of both scientific results of various authors and classes in biogeochemistry, that have been given to students by authors during the last 5 to 10 years at different universities throughout the world such as Cornell, Moscow, Seoul and Bangkok. Biogeochemistry is becoming an increasingly popular subject for graduate and postgraduate education. Courses in ecology, geography, biology, chemistry, environmental science, public health and environmental engineering all tend to have a biogeochemical component in their syllabuses to a greater or lesser extent.

Carefully crafted to provide a comprehensive overview of the chemistry of water in the environment, Water Chemistry: Green Science and Technology of Nature's Most Renewable Resource examines water issues within the broad framework of sustainability, an issue of increasing importance as the demands of Earth’s human population threaten to overwhelm the planet’s carrying capacity. Renowned environmental author Stanley Manahan provides more than just basic coverage of the chemistry of water. He relates the science and technology of this amazing substance to areas essential to sustainability science, including environmental and green chemistry, industrial ecology, and green (sustainable) science and technology. The inclusion of a separate chapter that comprehensively covers energy, including renewable and emerging sources, sets this book a part. Manahan explains how the hydrosphere relates to the geosphere, atmosphere, biosphere, and anthrosphere. His approach views Planet Earth as consisting of these five mutually interacting spheres. He covers biogeochemical cycles and the essential role of water in these basic cycles of materials. He also defines environmental chemistry and green chemistry, emphasizing water’s role in the practice of each. Manahan highlights the role of the anthrosphere, that part of the environment constructed and operated by humans. He underscores its overwhelming influence on the environment and its pervasive effects on the hydrosphere. He also covers the essential role that water plays in the sustainable operation of the anthrosphere and how it can be maintained in a manner that will enable it to operate in harmony with the environment for generations to come. Written at an intermediate level, this is an appropriate text for the study of current affairs in environmental chemistry. It provides a review and grounding in basic and organic chemistry for those students who need it and also fills a niche for an aquatic chemistry book that relates the hydrosphere to the four other environmental spheres.

Phosphorus is one of the major nutrients limiting the productivity of terrestrial, wetland and aquatic ecosystems. Over the last decade several research projects were conducted on Florida's ecosystems from state and federal agencies and private industry to address water quality issues, and to develop management practices to control nutrient loads. Phosphorus Biogeochemistry in Sub-Tropical Ecosystems is the first thorough study of the role of phosphorus in ecological health and water quality ever published. Because of its vast and extensively studied ecosystems, Florida has often served as a national laboratory on current and future trends in ecosystem management. The reader will find studies at all levels of biological organization, from the cellular to entire ecological communities. The book is a definitive study of the role and behavior of phosphorus deposition in the upland/wetland/aquatic environment. The papers presented in this book are organized in specific groups: ecological analysis and global issues, biogeochemical transformations, biogeochemical responses, transport processes, phosphorus management, and synthesis. Although Florida's ecosystems are used as a case study, the results presented have global applications.

This research topic highlights the most recent accomplishments of a Scientific Committee on Oceanic Research (SCOR) Working Group, SCOR WG 139: Organic Ligands - A Key Control on Trace Metal Biogeochemistry in the Ocean.
