The nanotechnology sector, which generated about $225 billion in product sales in 2009, is predicted to expand rapidly over the next decade with the development of new technologies that have new capabilities. The increasing production and use of engineered nanomaterials (ENMs) may lead to greater exposures of workers, consumers, and the environment, and the unique scale-specific and novel properties of the materials raise questions about their potential effects on human health and the environment. Over the last decade, government agencies, academic institutions, industry, and others have conducted many assessments of the environmental, health, and safety (EHS) aspects of nanotechnology. The results of those efforts have helped to direct research on the EHS aspects of ENMs. However, despite the progress in assessing research needs and despite the research that has been funded and conducted, developers, regulators, and consumers of nanotechnology-enabled products remain uncertain about the types and quantities of nanomaterials in commerce or in development, their possible applications, and their associated risks. A Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials presents a strategic approach for developing the science and research infrastructure needed to address uncertainties regarding the potential EHS risks of ENMs. The report summarizes the current state of the science and high-priority data gaps on the potential EHS risks posed by ENMs and describes the fundamental tools and approaches needed to pursue an EHS risk research strategy. The report also presents a proposed research agenda, short-term and long-term research priorities, and estimates of needed resources and concludes by focusing on implementation of the research strategy and evaluation of its progress, elements that the committee considered integral to its charge.

Nanotechnology a term encompassing nanoscale science, engineering, and technology is focused on understanding, controlling, and exploiting the unique properties of matter that can emerge at scales of one to 100 nanometers. A key issue before Congress regarding nanotechnology is how best to protect human health, safety, and the environment as nanoscale materials and products are researched, developed, manufactured, used, and discarded. While the rapidly emerging field of nanotechnology is believed by many to offer significant economic and societal benefits, some research results have raised concerns about the potential adverse environmental, health, and safety (EHS) implications of nanoscale materials. Stakeholders generally agree that concerns about potential detrimental effects of nanoscale materials and devices both real and perceived must be addressed to protect and improve human health, safety, and the environment; enable accurate and efficient risk assessment, risk management, and cost-benefit trade-offs; foster innovation and public confidence; and ensure that society can enjoy the widespread economic and societal benefits that nanotechnology may offer. Congressionally-mandated reviews of the National Nanotechnology Initiative (NNI) by the National Research Council and the President's Council of Advisors on Science and Technology have concluded that additional research is required to make a rigorous risk assessment of nanoscale materials.

Public policy analysts and political pundits alike tend to describe the policymaking process as a reactive sequence in which government develops solutions for clearly evident and identifiable problems. While this depiction holds true in many cases, it fails to account for instances in which public policy is enacted in anticipation of a potential future problem. Whereas traditional policy concerns manifest themselves through ongoing harms, "anticipatory problems" are projected to occur sometime in the future, and it is the prospect of their potentially catastrophic impact that generates intense speculation and concern in the present. Anticipatory Policymaking: When Government Acts to Prevent Problems and Why It Is So Difficult provides an in depth examination of the complex process through which United States government institutions anticipate emerging threats. Using contemporary debates over the risks associated with nanotechnology, pandemic influenza, and global warming as case study material, Rob A. DeLeo highlights the distinctive features of proactive governance. By challenging the pervasive assumption of reactive policymaking, DeLeo provides a dynamic approach for conceptualizing the political dimensions of anticipatory policy change.

An explosive increase in the knowledge of the effects of chemical and physical agents on biological systems has led to an increased understanding of normal cellular functions and the consequences of their perturbations. The 14-volume Second Edition of Comprehensive Toxicology has been revised and updated to reflect new advances in toxicology research, including content by some of the leading researchers in the field. It remains the premier resource for toxicologists in academia, medicine, and corporations. Comprehensive Toxicology Second Edition provides a unique organ-systems structure that allows the user to explore the toxic effects of various substances on each human system, aiding in providing diagnoses and proving essential in situations where the toxic substance is unknown but its effects on a system are obvious. Comprehensive Toxicology Second Edition is the most complete and valuable toxicology work available to researchers today. Contents updated and revised to reflect developments in toxicology research Organized with a unique organ-system approach Features full color throughout Available electronically on sciencedirect.com, as well as in a limited-edition print version
