An authoritative, in-depth exploration of the environmental consequences of nanotechnology Nanotechnology is revolutionizing the chemical, telecom, biotech, pharmaceutical, health care, aerospace, and computer industries, among others, and many exciting new nanotech applications are envisioned for the near future. While the rapid pace of innovation has been truly inspiring, much remains to be learned about the potential environmental and health risks posed by this nascent technology and its byproducts. So important is this issue that the ultimate success or failure of nanotechnology may well depend on how effectively science and industry address these concerns in the years ahead. Written by two highly accomplished environmental professionals, Nanotechnology: Environmental Implications and Solutions brings scientists, engineers, and policymakers up to speed on the current state of knowledge in this vitally important area. Professor Theodore and Dr. Kunz provide a concise review of nano-fundamentals and explore background issues surrounding nanotechnology and its environmental impact. They then follow up with in-depth discussions of: * The control, monitoring, and reduction of nanotech byproducts and their impact on the air, water, and land * Health risks associated with nanotechnology, and methods to assess and control them * Nanotech hazard risk assessment-including emergency response planning and personnel training * Multimedia approaches that are available for the analysis of the impact of nanotechnology in the chemical, manufacturing, and waste disposal industries * The future of nanotechnology and the "Industrial Revolution II" * The legal implications of nanotechnology * Societal and ethical implications of nanotechnology-based materials and processing method Assuming only a basic knowledge of physics, chemistry, and mathematics on behalf of its readers, Nanotechnology: Environmental Implications and Solutions makes fascinating and useful reading for engineers, scientists, administrators, environmental regulatory officials, and public policy makers, as well as students in a range of science and engineering disciplines.

The opening chapters introduce candidate nanomaterials, properties, mechanisms that enable the applications, the advantages and limitations compared to existing processes and commercial research requirements. It then explores the detection and application of nanomaterials in photocatalytic processes and as adsorbents, and also covers the effect of nanoparticles in the activated sludge process. Later chapters focus on the effects of nanoparticles on crops, the risks associated with the presence of nanoparticles in the environment, and lastly the environmental effects of nanoscale zero-valent iron (nZVI) on land remediation. This timely, multi-author contributed volume is aimed at students, technicians, and academics interested in the role, risks and benefits of nanotechnology in modern environmental contexts.
This book provides an account of the biogenic synthesis of nanomaterials by using different microorganisms. The chapters are focused on the biosynthesis of various metal and metal oxide nanosized materials by using bacteria, actinomycetes, fungi, and algae, including mechanisms of microbial synthesis. Other chapters summarize recent developments of microbial-based nanostructures for the management of food-borne pathogens, plant pathogenic fungi, as nutrients, and biomedical applications. Microorganisms are discussed not only as biofactories for the synthesis of nanomaterials but also as removal agents of toxic metals from the environment. Exposure sources and ecotoxicity of microbially synthesized nanoparticles are also discussed.

The pollution of soil and groundwater by heavy metals and other chemicals is becoming a serious issue in many countries. However, the current bioremediation processes do not often achieve sufficient remediation, and more effective processes are desired. This book deals with advances in the bioremediation of polluted soil and groundwater. In the former chapters of this book, respected researchers in this field describe how the optimization of microorganisms, enzymes, absorbents, additives and injection procedures can help to realize excellent bioremediation. In the latter chapters, other researchers introduce bioremediation processes that have been performed in the field and novel bioremediation processes. Thus, the readers will be able to obtain new ideas about effective bioremediation as well as important information about recent advances in bioremediation.
The World Health Organization in 2004 estimated approximately 1.1 billion people did not have access to clean water and that 35% of Third World residents died from water-borne illnesses. While the situation is grim, recent advances strongly indicate that many of the current water quality problems can be addresses – and potentially resolved – using nanotechnology. Nanotechnology is already having a dramatic impact on research in water quality and Nanotechnology Applications for Clean Water highlights both the challenges and the opportunities for nanotechnology to positively influence this area of environmental protection. Here you will find detailed information on breakthroughs, cutting edge technologies, current research, and future trends that may affect acceptance of widespread applications. The first four parts of the book cover specific topics including using nanotechnology for clean drinking water in both large scale water treatment plants and in point-of-use systems. For instance, recent advances show that many of the current problems involving water quality can be addressed using nanosorbents, nanocatalysts, bioactive nanoparticles, nanostructured catalytic membranes, and nanoparticle enhanced filtration. The book also discusses existing technologies and future potential for groundwater remediation, pollution prevention, and sensors. The final part discusses the inherent societal implications that may affect acceptance of widespread applications. Over 80 leading experts from around the world share their wealth of knowledge in this truly unique reference. Institutions such as Center for the Purification of Water and Systems (Univ. of Illinois at Urbana-Champaign); UCLA Water Technology Center; Carnegie Mellon University, University of Kentucky; The University of Western Ontario; Pacific Northwest National Laboratory; National Institute for Advanced Industrial Science and Technology (Japan), Munasinghe Institute for Development (Sri Lanka) and the Woodrow Wilson Center for Scholars are just a few of the knowledge centers represented in this book. Water quality is a serious, global issue in which government bodies and scientific communities face many challenges in ensuring clean water is available to everyone. Nanotechnology is already showing dramatic results, and this book is an attempt to share current technologies and future possibilities in reaching this goal.
