Triennial Review of the National Nanotechnology Initiative


Book Description

The National Nanotechnology Initiative (NNI) is a multiagency, multidisciplinary federal initiative comprising a collection of research programs and other activities funded by the participating agencies and linked by the vision of "a future in which the ability to understand and control matter at the nanoscale leads to a revolution in technology and industry that benefits society." As first stated in the 2004 NNI strategic plan, the participating agencies intend to make progress in realizing that vision by working toward four goals. Planning, coordination, and management of the NNI are carried out by the interagency Nanoscale Science, Engineering, and Technology (NSET) Subcommittee of the National Science and Technology Council (NSTC) Committee on Technology (CoT) with support from the National Nanotechnology Coordination Office (NNCO). Triennial Review of the National Nanotechnology Initiative is the latest National Research Council review of the NNI, an assessment called for by the 21st Century Nanotechnology Research and Development Act of 2003. The overall objective of the review is to make recommendations to the NSET Subcommittee and the NNCO that will improve the NNI's value for basic and applied research and for development of applications in nanotechnology that will provide economic, societal, and national security benefits to the United States. In its assessment, the committee found it important to understand in some detail-and to describe in its report-the NNI's structure and organization; how the NNI fits within the larger federal research enterprise, as well as how it can and should be organized for management purposes; and the initiative's various stakeholders and their roles with respect to research. Because technology transfer, one of the four NNI goals, is dependent on management and coordination, the committee chose to address the topic of technology transfer last, following its discussion of definitions of success and metrics for assessing progress toward achieving the four goals and management and coordination. Addressing its tasks in this order would, the committee hoped, better reflect the logic of its approach to review of the NNI. Triennial Review of the National Nanotechnology Initiative also provides concluding remarks in the last chapter.



















Twenty-second Interim Report of the Committee on Acute Exposure Guideline Levels


Book Description

In 1991, the Environmental Protection Agency (EPA) and the Agency for Toxic Substances and Disease Registry (ATSDR) asked the National Research Council (NRC) to provide technical guidance for establishing community emergency exposure levels for extremely hazardous substances (EHSs) pursuant to the Superfund Amendments and Reauthorization Act of 1986. As a result the NRC published Guidelines for Developing Community Emergency Exposure Levels for Hazardous Substances in 1993 and Standing Operating Procedures for Developing Acute Exposure Guideline Levels for Hazardous Substances in 2001; providing updated procedures, methods, and other guidelines used by the National Advisory Committee (NAC) on Acute Exposure Guideline Levels (AEGLs) for hazardous substances for assessing acute adverse health effects. Stemming from this report the NAC has developed AEGLs for at least 270 EHSs. There are currently three AEGLs: AEGL-1, AEGL-2, and AEGL-3. AEGL-1 is the airborne concentration of a substance above which it is predicted that the general population could experience notable discomfort, irritation, or certain asymptomatic nonsensory effects. These effects are not disabling and are transient and reversible once exposure is stopped. AEGL-2 is the airborne concentration (of a substance above which it is predicted that the general population could experience irreversible, long-lasting adverse health effects or an impaired ability to escape. AEGL-3 is the airborne concentration of a substance above which it is predicted that the general population could experience life threatening health effects or death. On April 22-24 2013, the NRC-established Committee on Acute Exposure Guideline Levels 2013 met to review AEGL documents approved by the NAC. The committee members were selected for their expertise in toxicology, medicine, industrial hygiene, biostatistics, and risk assessment. Twenty-second Interim Report of the Committee on Acute Exposure Guideline Levels presents a review of AEGLs for various chemicals including acrylonitrile, halogen fluorides, tellurium hexafluoride, and thionyl chloride.
