Book excerpt: 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

Book excerpt: This book discusses nanotechnology, its benefits and risks affecting the environment we live in today, and is divided into three parts: Part-I dealing with Sustainability, Part-II describing Toxicological Impacts, and Part-III discussing Nanomaterial-based Adsorbents. The crucial challenge of sustainability in various environmental elements is a global problem. This draws upon various issues of nanotechnology which impact sustainability of food, clean environment, green house gases, raw materials extraction, manufacturing and automobile industry. Growth in the production of nanomaterials to suit any of these applications is commendable. However, this does not negate the growth in their toxic effects. The nanotoxicity research in areas like medicine and agriculture industry is reviewed in detail in this book. Part-II discusses the toxic nature of widely used nanomaterials. Nanomaterials are enormously used in environmental remediation due to some of their distinct properties. These properties are described and discussed. Part-III of the book highlights the highly reactive and adsorbent properties of nanomaterials that enable them to be a competent agent in water and pollutant remediation. This book is mainly intended for researchers and students to acquire fairly comprehensive understanding and appreciation of nanotechnology dominance in sustainability challenges, with the aim to give the anticipatory governance of nanomaterials in our society and environment.

Book excerpt: Dyes, pigments and metals are extensively used in food, paper, carpet, rubber, plastics, cosmetics, and textile industries, in order to color and finish products. As a result, they generate a considerable amount of coloured wastewater rich in organic, inorganic, and mineral substances which are continuously polluting the water bodies and affecting human and aquatic life. Besides these industries, urban and agricultural activities also generate effluents high in biochemical oxygen demand (BOD) and chemical oxygen demand (COD). In recent years, considerable research work has been done in this area and is underway to eliminate heavy metals particularly mercury (Hg), chromium (Cr), lead (Pb), selenium and cadmium (Cd) and synthetic dyes from polluted waters which have high toxicity and carcinogenicity. Currently a number of methods are in operation to decontaminate the polluted waters. Among several purification technologies, use of nanoparticles/composites have gained much attention as efficient purification technology due to its many advantages such as simple synthesis, special chemical and physical properties, unique photocatalytic activity and beneficial antimicrobial properties and high efficiency. The book Environmental Nanotechnology for Water Purification comprehensively covers and provides new insights on all nanoparticles, composites and advanced methods employed in water purification.
