This valuable resource discusses several strategies of manipulating colloids for environmental restoration, identifies advantages and disadvantages of each strategy, and considers obstacles limiting the application of each strategy. Approaches evaluated include the following: Chemical modification of subsurface systems to mobilize or deposit colloids in situ Altering the mobility of microorganisms to improve delivery of microbes for bioremediation Manipulating colloids or biocolloids (bacteria) to change aquifer permeability to either enhance bioremediation or create in situ barriers Introducing modified colloids, surfactants, and emulsions to control colloid mobility or to increase recovery of sorbed contaminants by pump and treat methods Manipulation of Groundwater Colloids for Environmental Restoration also contains short, focused research reports on specific studies relevant to the various approaches under consideration. Subjects covered range from mobility of organic macromolecules by controlled field injection experiments to new techniques that investigate surface chemistry and aggregation of inorganic colloids. Other topics discussed include the depositional behavior and transport of biocolloids in porous media, surfactants as modifiers of surface binding sites on colloids, and genetic engineering of microorganisms to serve as contaminant-scavenging biocolloids. Manipulation of Groundwater Colloids for Environmental Restoration is an excellent resource for research scientists in hydrology, chemistry, and microbiology; environmental consultants; regulators; environmental engineers; bioremediation microbiologists; and engineers.

Metal Speciation and Contamination of Soil provides a thorough overview of the biogeochemical processes governing the behavior, transport, and bioavailability of heavy metals in contaminated soils and suggests alternative approaches for effective remediation. This important new book contains contributions from experts in various disciplines who explore the issues from theoretical, experimental, and pragmatic perspectives. Topics include redox chemistry, kinetics of metal reactions, spectroscopic characterization of metal ion reactions at surface, modeling hydrologic transport phenomena and colloid-associated transport of metals through the soil profile to ground water, and remediation alternatives.

The hydrological and geochemical interactions between clay minerals and organic matter in soils directly influence the reaction, behavior, and mobility of heavy metals in soils. Geochemical and Hydrological Reactivity of Heavy Metals in Soils is one of few books that comprehensively illustrates this cause-and-effect relationship. It highlights anal

Environmental Particles, Volume 2 presents a review of the sampling, characterization, and behavior of particles in air, water, sediments, and solids. The book analyzes the formation, aggregation, transport, and conversion of particles, and evaluates the capabilities of physical and chemical analytic methods. It also discusses physicochemical properties of environmental particles, their spectroscopic characterization and colloid chemical properties, and how they affect biochemical and toxicological processes. This book is an important reference for environmental chemists, limnologists, oceanographers, air and soil scientists, analytical chemists, environmental engineers, students, and more.

This guide book provides references and resources for the complex field of hazardous waste and hazardous materials management. The book is divided into general topics such as air quality, industrial wastewater, pollution prevention, and risk assessment under hazardous waste management and chemical hazards, emergency planning, and hazard communication under hazardous materials management. Each individual section includes a list of annotated bibliographies of the most recent books by major publishers as well as established, standard references. Following the annotated titles, are additional references of books and documents by publishers, technical associations, and governmental agencies (primarily the U.S. Environmental Protection Agency). In general, only references from 1986 onward are included since the technology and regulations affecting hazardous waste and materials are constantly evolving.Additional resources included in the book are video tapes for training and instruction, information services and databases, libraries, agency contacts, technical journals, and a list of publishers and ordering information. This book will be a useful reference to professionals in the environmental field who need an extensive, but concise source of technical information and contacts.The book will be a valuable addition to individual libraries and will fill a current reference void in university libraries, and technical libraries in industry and government. At present there are very few technical bibliographies in the field, and none has covered topics related to hazardous materials and hazardous waste as extensively as this book.

BACTERIAL ADHESION Molecular and Ecological Diversity Edited byMadilyn Fletcher Over the last twenty years, research has revealed the enormouscomplexity underlying the phenomenon of bacterial adhesion. Theinitial research goal was to understand the mechanism of attachmentand its effects on the bacteria as well as the host. As researchprogressed, however, it became evident that many differentattachment mechanisms exist. These diverse forms of adhesion arethe results of numerous evolutionary pressures, and each may bepart of a larger behavioral strategy. This comprehensive overview details how diversity in habitat andecological requirements has led to enormous variety in adhesivecell components, underlying genetic determinants, and behavioralstrategies. It presents the latest research on adhesion mechanismsand strategies found in diverse environments and microorganisms,including the new environment of biomaterials. Bacterial Adhesion: Molecular and Ecological Diversity examinesadhesion as a strategy for nutrient access and as a phase in thecomplex behavior of life cycle processes. It covers the latestresearch and innovative approaches in the field, including: * Conceptual advances in research on the adhesion of bacteria tooral surfaces * Enhancing colonization in a fluctuating environment * The cellulosome: a cell-surface organelle for the adhesion to anddegradation of cellulose * Pseudomonas aeruginosa--versatile attachment mechanisms * Sensing, response, and adaptation to surfaces * Myxococcus coadhesion and role in the life cycle Edited by a leading authority on bacterial adhesion and featuringcontributions from the field's leading experts, this book speaks toresearchers in all areas of microbiology, biotechnology,environmental technology, and environmental science, as well asurology, immunology, and infectious diseases. Bacterial Adhesion: Molecular and Ecological Diversity is thelatest addition to the Wiley Series in Ecological and AppliedMicrobiology. Recent books in the series include: * Microbial Transformation and Degradation of Toxic OrganicChemicals edited by Lily Y. Young and Carl E. Cerniglia * Wastewater Microbiology by Gabriel Bitton * Environmental Microbiology edited by Ralph Mitchell * Biotechnology in Plant Disease Control edited by Ilan Chet * Antarctic Microbiology edited by E. Imre Friedmann * Effects of Acid Rain on Forest Processes edited by Douglas L.Godbold and Aloys Huttermann

FROM THE INTRODUCTION This three-volume set, Bioremediation: Principles and Practice, provides state of the art description of advances in pollution treatment and reduction using biological means; identify and address, at a fundamental level, broad scientific and technological areas that are unique to the subject or theme and that must be understood if advances are to be made; and provide a comprehensive overview of new developments at the regulatory, desk-top, bench-scale, pilot scale, and full-scale levels. The set covers all media-air, water, and soil/sediment-and blends the talents, knowledge, and know-how of academic, industrial, governmental, and international contributors. The set addresses the removal of both hazardous and nonhazardous contaminants from the liquid, solid, and gas phase using biological processes. This includes the biological treatment of wastes of municipal and industrial origin; bioremediation of leachates, soils, and sediments; and biofiltration for contaminated gases.
