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

Despite the increase in funding for research and the rising numbers of peer-reviewed publications over the past decade that address the environmental, health, and safety aspects of engineered nanomaterials (ENMs), uncertainty about the implications of potential exposures of consumers, workers, and ecosystems to these materials persists. Consumers and workers want to know which of these materials they are exposed to and whether the materials can harm them. Industry is concerned about being able to predict with sufficient certainty whether products that it makes and markets will pose any environmental, health or safety issues and what measures should be taken regarding manufacturing practices and worldwide distribution to minimize any potential risk. However, there remains a disconnect between the research that is being carried out and its relevance to and use by decision-makers and regulators to make informed public health and environmental policy and regulatory decisions. Research Progress on Environmental, Health, and Safety Aspects of Nanomaterials evaluates research progress and updates research priorities and resource estimates on the basis of results of studies and emerging trends in the nanotechnology industry. This report follows up the 2012 report A Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials, which presented a strategic approach for developing the science and research infrastructure needed to address uncertainties regarding the potential environmental, health, and safety risks posed by ENMs. This new report looks at the state of nanotechnology research, examines market and regulatory conditions and their affect on research priorities, and considers the criteria for evaluating research progress on the environmental, health, and safety aspects of nanotechnology.

An overview of the current state of nanotechnology-based devices with applications in environmental science, focusing on nanomaterials and polymer nanocomposites. The handbook pays special attention to those nanotechnology-based approaches that promise easier, faster and cheaper processes in environmental monitoring and remediation. Furthermore, it presents up-to-date information on the economics, toxicity and regulations related to nanotechnology in detail. The book closes with a look at the role of nanotechnology for a green and sustainable future. With its coverage of existing and soon-to-be-realized devices this is an indispensable reference for both academic and corporate R&D.
