Should you adopt nanotechnology? If you have already adopted it, what do you need to know? What are the risks? Nanomaterials and nanotechnologies are revolutionizing the ways we treat disease, produce energy, manufacture products, and attend to our daily wants and needs. To continue to capture the promise of these transformative products, however, we need to ask critical questions about the broader impacts of nanotechnology on society and the environment. Exploring these questions, the second edition of Nanotechnology: Health and Environmental Risks gives you the latest tools to understand the risks of nanotechnology and make better decisions about using it. Examining the state of the science, the book discusses what is known, and what still needs to be understood, about nanotechnology risk. It looks at the uses of nanotechnology for energy, industry, medicine, technology, and consumer applications and explains how to determine whether there is risk—even when there is little reliable evidence—and how to manage it. Contributors cover a wide range of topics, including: Current concerns, among them perceived risks and the challenges of evaluating emerging technology A historical perspective on product safety and chemicals policy The importance of being proactive about identifying and managing health and environmental risks during product development How the concepts of sustainability and life cycle assessment can guide nanotechnology product development Methods for evaluating nanotechnology risks, including screening approaches and research How to manage risk when working with nanoscale materials at the research stage and in occupational environments What international organizations are doing to address risk issues How risk assessment can inform environmental decision making Written in easy-to-understand language, without sacrificing complexity or scientific accuracy, this book offers a wide-angle view of nanotechnology and risk. Supplying cutting-edge approaches and insight, it explains what types of risks could exist and what you can do to address them. What’s New in This Edition Updates throughout, reflecting advances in the field, new literature, and policy developments A new chapter on nanotechnology risk communication, including insights into risk perceptions and the mental models people use to evaluate technological risks An emphasis on developing nanotechnology products that are sustainable in the long term Advances in the understanding of nanomaterials toxicity Cutting-edge research on occupational exposure to nanoparticles Changes in the international landscape of organizations working on the environmental, health, and safety aspects of nanotechnologies

Extensively revised and featuring new material, this timely, advanced resource covers the impacts of nanomaterials on organisms and ecosystems and their applications within industry. Cowritten by leaders of two of the most prominent research groups in the world considering the effects of nanomaterials on the environment, the second edition of Environmental Nanotechnology addresses the cutting-edge advances in this area. There is now much more known about the impacts of nanomaterials on organisms and ecosystems. Methods have been developed where there were few accepted procedures in the past. Thinking has evolved to consider the life cycle effects of nanomaterial production, and tools for risk forecasting are now under development. There has also been some experience among academics in using this book as the basis for new courses on Environmental Nanotechnology. Three new chapters cover the life cycle of nanomaterial fabrication and use and estimating nanomaterial exposure in the environment. A systematic discussion of the effects of nanomaterials on organisms and ecosystems is included, where the previous edition was largely limited to speculation. Features 75% new material New chapter on the life cycle aspects of nanomaterial fabrication and use Two new chapters on estimating nanomaterial exposure in the environment: implications that explore nanotoxicology; exposure estimation Contains end-of-chapter problems and questions

The Royal Commission's decision to study novel materials was motivated by concern about the potential for releases to the environment arising from increasing industrial applications of metals and minerals that have not previously been widely used and, secondly, by the embodiment of nanoparticles and nanotubes in a wide range of consumer products and specialist applications in fields such as medicine and environmental remediation. Most of the evidence received focused on nanomaterials - particles, fibres and tubes on the scale of a few billionths of a metre. Chapters 2 and 3 explore the extent to which novel substances are currently being deployed, the plausible pathways by which they might enter the environment, their likely environmental destinations in use or disposal and the possible consequences of their release to those destinations. Chapter 4 considers what arrangements would be most appropriate for the governance of emerging technologies under two conditions that pose serious constraints on any regulator. First is the condition of ignorance about the possible environmental impacts in the absence of any kind of track record for the technology. Second is the condition of ubiquity - the fact that new technologies no longer develop in a context of local experimentation but emerge as globally pervasive systems - which challenges both trial-and-error learning and attempts at national regulation. Both new governance approaches and modifications to existing ones are likely to be called for. They will need to be rooted in ideas of adaptive management that require multiple perspectives on the issues. The Commission's recommendations are based on the premise that it is the functionality of the material, not particle size or mode of production, which is critical for evaluating its potential impact on the environment or human health.

Nanotechnology manipulates matter at the atomic level. It leads to innovative processes and products that are revolutionizing many areas of modern life. Huge amounts of public funds are being invested in the science, yet the public has little understanding of the technology or its ethical implications. Indeed, the ethical, social, and political dimensions of nanotechnology are only beginning to receive the attention they require - outside of science fiction contexts. Surveillance devices may become so small that they are practically invisible to the naked eye, raising concerns about privacy. Nanomedicine may lead to the development of new diagnostic and therapeutic devices, yet anxieties have been raised about the impact of "nanobots" circulating in our bodies. Military applications, or misuses, of nanotechnology raise other concerns. This book explores in an accessible and informative way how nanotechnology is likely to impact the lives of ordinary people in the coming years and why ethical reflection on nanotechnology is needed now.
