NNI Publishes Outcomes of the 2015 EU-U.S.: Bridging NanoEHS Research Efforts Joint Workshop

The National Nanotechnology Initiative (NNI) published on March 23, 2015, the outcomes of the March 12-13, 2015, joint workshop held by the U.S. and the European Union (EU), “Bridging NanoEHS Research Efforts.”  The workshop was intended to promote and deepen the collaboration on nanotechnology environmental, health, and safety (nanoEHS) research.  Workshop participants reviewed progress toward U.S.-EU Communities of Research (COR) goals and objectives, shared best practices, and identified areas for cross-COR collaboration.  To address new challenges, the CORs were realigned and expanded with the addition of a COR on nanotechnology characterization.  The seven CORs now address:

  • Characterization;
  • Databases and Computational Modeling;
  • Exposure through Product Life;
  • Ecotoxicity;
  • Human Toxicity;
  • Risk Assessment; and
  • Risk Management and Control.

According to the workshop outcomes, the CORs support the shared goal of responsible nanotechnology development as outlined in the U.S. NNI Environmental, Health, and Safety Research Strategy, and the research strategy of the EU NanoSafety Cluster.  The CORs directly address several priorities described in these documents, including the creation of a comprehensive nanoEHS knowledge base and international cooperation on the development of best practices and consensus standards. 

EU-U.S. Joint NanoEHS Workshop Will Be Held in March 2015 in Italy

 The National Nanotechnology Coordination Office (NNCO) announced on December 5, 2014, that, in collaboration with the European Commission (EC), it will hold the 2015EU-U.S.:  Bridging NanoEHS Research Efforts” joint workshop on March 12-13, 2015, in Venice, Italy.  According to NNCO, the workshop will bring together the U.S.-European Union (EU) Communities of Research (COR), which serve as a platform for U.S. and EU scientists to share information on nano environmental health and safety (EHS) research.  NNCO states that this workshop, the fourth since 2011, is intended to develop further and support the CORs’ activities.  The six CORs are:

  • Exposure through the Life Cycle, with Material Characterization;

  • Ecotoxicity Testing and Predictive Models, with Material Characterization;

  • Predictive Modeling for Human Health, with Material Characterization;

  • Databases and Ontologies;

  • Risk Assessment; and

  • Risk Management and Control.

Due to space limitations, pre-registration for the workshop is required.  Registration is on a first-come, first-served basis and will be capped at approximately 100 participants.  Registration is now open.

NIOSH Publishes Progress Report from Nanotechnology Research Center

On November 7, 2012, the National Institute for Occupational Safety and Health (NIOSH) Nanotechnology Research Center (NTRC) posted a document entitled Filling the Knowledge Gaps for Safe Nanotechnology in the Workplace: A Progress Report from the NIOSH Nanotechnology Research Center, 2004–2011. NIOSH established NTRC in 2004 to address occupational safety and health concerns associated with nanotechnology. The progress report summarizes program accomplishments from the inception of NTRC in 2004 through 2011. It includes an analysis of the progress made toward accomplishing the goals and objectives of the NIOSH Strategic Plan for Nanotechnology Research and toward addressing the goals and research needs identified in the National Nanotechnology Initiative (NNI) environmental, health, and safety (EHS) research strategy. The progress report states that NTRC “continues to support and promote the responsible development of nanotechnology through its ongoing research program and its contributions to the development of guidelines for hazard identification, exposure assessment, and risk characterization that can be used to develop and implement effective risk management practices.”

CRS Publishes Nanotechnology Policy Primer

The Congressional Research Service (CRS) published an April 13, 2012, document entitled Nanotechnology: A Policy Primer that provides an overview of federal research and development (R&D) in nanotechnology, U.S. competitiveness, environmental, health, and safety (EHS) concerns, nanomanufacturing, and public understanding of and attitudes toward nanotechnology. CRS states that, since the launch of the National Nanotechnology Initiative (NNI) in 2000 through fiscal year (FY) 2012, Congress has appropriated approximately $15.6 billion for nanotechnology R&D, including approximately $1.7 billion in FY 2012. President Obama has requested $1.8 billion in NNI funding for FY 2013. More than 60 nations have established similar programs, and, according to CRS, in 2010, the total global public R&D investments were approximately $8.2 billion, complemented by an estimated private sector investment of $9.6 billion.  Based on the data on inputs (e.g., R&D expenditures) and non-financial outputs (e.g., scientific papers, patents), the U.S. appears to be the overall global leader in nanotechnology, though CRS cautions that some believe the U.S. lead “may not be as large as it was for previous emerging technologies.” According to CRS, some research has raised concerns about the safety of nanoscale materials, and “[t]here is general agreement that more information on EHS implications is needed to protect the public and the environment; to assess and manage risks; and to create a regulatory environment that fosters prudent investment in nanotechnology-related innovation.”

NRC Publishes A Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials

On January 25, 2012, the National Research Council (NRC) posted the pre-publication version of its report entitled A Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials. The U.S. Environmental Protection Agency (EPA) asked NRC to perform an independent study to develop and monitor the implementation of an integrated research strategy to address the environmental, health, and safety (EHS) aspects of engineered nanomaterials (ENM). NRC convened the Committee to Develop a Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials, which concluded that there is need for a research strategy that is independent of any one stakeholder group, has human and environmental health as its primary focus, builds on past efforts, and is flexible in anticipating and adjusting to emerging challenges.

To help guide research, the Committee noted the following four research categories, which it states should be addressed within five years:

  • Identify and quantify the nanomaterials being released and the populations and environments being exposed;
  • Understand processes that affect both potential hazards and exposure;
  • Examine nanomaterial interactions in complex systems ranging from subcellular to ecosystems; and
  • Support an adaptive research and knowledge infrastructure for accelerating progress and providing rapid feedback to advance research.

The Committee acknowledged a gap between funding and the level of activity required to support its strategy. The Committee concluded that any reduction in the current funding level of approximately $120 million per year over the next five years for health and environmental risk research by federal agencies would be a setback to nanomaterials risk research. Moreover, according to the Committee, additional “modest resources” from public, private, and international initiatives are needed in critical areas -- informatics, nanomaterial characterization, benchmarking nanomaterials, characterization of sources, and development of networks for supporting collaborative research -- to derive maximum strategic value from the research investments.

The Committee states that implementation of the strategy should also include the integration of domestic and international participants involved in nanotechnology-related research, including the National Nanotechnology Initiative (NNI), federal agencies, the private sector, non-governmental organizations, and the academic community. The Committee noted that the current structure of the NNI, which has no top-down budgetary or management authority to direct nanotechnology-related EHS research, hinders its accountability for effective implementation. In addition, according to the Committee, there is concern that dual and potentially conflicting roles of the NNI, such as developing and promoting nanotechnology while identifying and mitigating risks that arise from its use, impede application and evaluation of health and environmental risk research. The Committee concluded that, to carry out the research strategy effectively, a clear separation of management and budgetary authority and accountability between promoting nanotechnology and assessing potential environmental and safety risks is essential.


ObservatoryNANO Posts Report on Nanotechnology EHS Landscape

ObservatoryNANO posted on November 24, 2011, a report on the nanotechnology environment, health, and safety (EHS) landscape. ObservatoryNANO, which is funded by the European Commission, intends to support European policy makers by providing scientific and economic analysis of nanoscience and nanotechnology developments. ObservatoryNANO notes that activity concerned with the EHS aspects of nanotechnologies has been growing for a decade.  ObservatoryNANO states that the aim of the EHS landscaping report is to provide a map and overview of key organizations and their activities within the field worldwide in relation to nano-EHS.  ObservatoryNANO intends the landscaping document to support communication of efforts, outlining those key initiatives, activities, and projects within the field.  According to ObservatoryNANO, because of the challenge of keeping track of the rapidly changing field, the landscaping document provides only a snapshot of efforts ongoing within 2011, and will change with time.

ObservatoryNANO identified and grouped key organizations and projects into seven major areas:

  • Research;
  • Knowledge Transfer and Review;
  • Standardization;
  • Guidance;
  • Regulation;
  • Public Engagement; and
  • Professional Bodies.

The landscaping document provides a short overview of the organizations working within each area, together with links and references to further information.

NNI Releases Reports from EHS Workshops

On July 19, 2011, the National Nanotechnology Initiative (NNI) announced the release of four reports from a series of workshops focusing on issues in the nanotechnology environmental, health, and safety (EHS) arena. According to NNI, the workshops were a part of an ongoing strategy to coordinate nanotechnology-related EHS research by convening experts from industry, academia, and the federal government to share the latest information and newest developments, to discuss the current state-of-the-science, and to identify research gaps in the nanotechnology-related EHS field. NNI states that “knowledge gleaned from the nanoEHS workshop series was critical to the development of the soon-to-be-released, updated NNI EHS Research Strategy.”

Through four separate workshops, experts examined the following areas:

  • Nanomaterials and Human Health and Instrumentation, Metrology, and Analytics;
  • Nanomaterials and the Environment and Instrumentation, Metrology, and Analytics;
  • Human and Environmental Exposure Assessment; and
  • Risk Management Methods and Ethical, Legal, and Societal Implications of Nanotechnology.

Bergeson is included in the Nanotechnology Law & Business list of the top ten experts in environmental, health, and safety (EHS) issues related to engineered nanomaterials. Nanotechnology Law & Business states that they chose ten individuals with “substantial expertise” in EHS issues related to engineered nanomaterials and that they “expect these individuals to play leading roles in nanotechnology law and business.” Nanotechnology Law & Business is a peer-reviewed journal devoted to the legal, business, and policy aspects of small scale technologies.

NNCO Responds to NRC Report on Nanotechnology Research Strategy

On February 13, 2009, the National Nanotechnology Coordination Office (NNCO) released a statement regarding the National Research Council’s (NRC) December 10, 2008, report regarding its review of the National Nanotechnology Initiative (NNI) Strategy for Nanotechnology-Related Environmental, Health, and Safety (EHS) Research.  According to the statement, NNI member agencies noted the report’s “substantial and important recommendations for further progress on EHS research,” and “look forward to working with the NRC on achieving the vital and shared goals of clearly, proactively assessing the potential benefits and risks that may be associated with specific nanomaterials in specific applications.”  NNCO notes that it “do[es] not believe that the NRC evaluation recognized the breadth and depth of the NNI commitment to EHS research. . . .  Furthermore, the report drew a number of conclusions with which the NNI member agencies respectfully disagree.” NNCO provided detailed comments to the NRC in a January 5, 2009, letter. On February 24-25, 2009, NNCO held a workshop regarding the science related to EHS aspects of engineered nanoscale materials in the area of human and environmental exposure assessment, one of the five EHS research categories identified in the Strategy for Nanotechnology-Related Environmental, Health, and Safety Research.

Bill to Reauthorize NNI Introduced in Senate

On July 17, 2007, Senators Daniel K. Inouye (D-HI), Chair of the Commerce, Science, and Transportation Committee, John Kerry (D-MA), Olympia Snowe (R-ME), Ted Stevens (R-AK), Mark Pryor (D-AR) and Gordon Smith (R-OR) introduced the National Nanotechnology Initiative Amendments Act of 2008. The bill would reauthorize the National Nanotechnology Initiative (NNI) and amend aspects of the program to prioritize better research and development activities.

Specifically, the bill would:

  • Establish the National Nanotechnology Advisory Panel, which would be responsible for recommending an appropriate funding level for the environmental, health, and safety (EHS) program component area. The bill would also establish a subpanel focused on the societal, ethical, legal, environmental, and workforce issues related to nanotechnology;
  • Provide consistent funding for the National Nanotechnology Coordination Office (NNCO) through the participating federal agencies;
  • Require the NNCO to establish a publicly available database of the projects funded in the EHS program component area, the educational and societal dimensions program component area, and the nanomanufacturing program component area;
  • Require an Office of Science and Technology Policy official to serve as the Coordinator for Societal Dimensions of Nanotechnology. The Coordinator would be required to develop and annually update a research plan for the EHS program component area;
  • Support the development of standards, metrology, and characterization tools for nanotechnology;
  • Promote technology transfer through the Small Business Innovation Research Program and the Small Business Technology Transfer Program, and make federally funded nanotechnology facilities available to companies to assist in the development of prototypes of nanoscale products, devices, or processes;
  • Promote nanotechnology research and development in areas of national importance, including nano-electronics, energy efficiency, health care, water remediation, instrumentation and characterization, and rapid production nanomanufacturing;
  • Require the Government Accountability Office to conduct a comprehensive study of federal codes, standards, and regulations as they relate to the safe production, use, and disposal of engineered nanomaterials and products containing nanomaterials; and
  • Require the NNCO to engage the public by convening a national discussion on nanotechnology. This national discussion would include diverse participation and incorporate the views of academia, nongovernmental organizations, and industry to identify priorities and concerns related to nanotechnology research and development, products, and regulatory policy.

GAO Testifies Before Senate Subcommittee on the Accuracy of Data Concerning Federally Funded EHS Research

On April 24, 2008, the U.S. Government Accountability Office (GAO) released a report entitled Nanotechnology: Accuracy of Data on Federally Funded Environmental, Health, and Safety Research Could Be Improved, which contains the testimony of Robert A. Robinson, Managing Director, Natural Resources and Environment, before the Senate Committee on Commerce, Science, and Transportation Subcommittee on Science, Technology, and Innovation. Robinson provided a summary of GAO’s findings as reported in its March 31, 2008, report entitled Nanotechnology: Better Guidance Is Needed to Ensure Accurate Reporting of Federal Research Focused on Environmental, Health, and Safety Risks. GAO was asked to focus on: (1) the extent to which selected agencies conducted environmental, health, and safety (EHS) research in fiscal year (FY) 2006; (2) the reasonableness of the agencies’ and the National Nanotechnology Initiative’s (NNI) processes to identify and prioritize EHS research; and (3) the effectiveness of the agencies’ and the NNI’s process to coordinate EHS research. According to NNI, in FY 2006, federal agencies devoted $37.7 million -- or three percent of the $1.3 billion total nanotechnology research funding -- to research primarily focused on the EHS risks of nanotechnology, according to the NNI. GAO found that about 20 percent of this total could not actually be attributed to this purpose, however. GAO states that 22 of the 119 projects identified as EHS in FY 2006 were not primarily related to understanding the extent to which nanotechnology may pose an EHS risk. Instead, many of the projects focused on how to use nanotechnology to remediate environmental damage or detect hazards not related to nanotechnology. GAO states that, at the time of its review, federal agencies and NNI were in the process of identifying and prioritizing EHS risk research needs, and the overall process they were using appeared reasonable. NNI also was engaged in an iterative prioritization effort through its Nanotechnology Environmental and Health Implications (NEHI) working group. NEHI identified five general research categories as a priority for federally funded research. GAO found that most of the research projects that were underway in FY 2006 were generally consistent with agency and NEHI priorities. NEHI released its new EHS research strategy on February 13, 2008. According to GAO, agency and NNI processes to coordinate activities related to potential EHS risks of nanotechnology have been generally effective. In its March 2008 report, GAO recommended better guidance to improve the accuracy of data reported by NNI. Although the Office of Science and Technology Policy (OSTP) asserted that it provides extensive guidance, it agreed to review how the agencies respond to the current guidance. Robinson made no new recommendations in his statement before the Subcommittee.

NSET Releases Strategy for Nanotechnology-Related EHS Research

On February 14, 2008, the Nanoscale Science, Engineering, and Technology (NSET) Subcommittee of the National Science and Technology Council’s Committee on Technology released a final document entitled Strategy for Nanotechnology-Related Environmental, Health, and Safety Research, which describes the National Nanotechnology Initiative’s (NNI) strategy for addressing priority research on the environment, health, and safety (EHS) aspects of nanomaterials. The NNI EHS Strategy assigns priority to research and information needs identified by the NSET Subcommittee. NNI released an interim version of the EHS Strategy in August 2007, entitled Prioritization of Environmental, Health, and Safety Research Needs for Engineered Nanoscale Materials: An Interim Document for Public Comment. NNI incorporated public comments in preparing the final EHS Strategy. The Nanotechnology Environmental and Health Implications (NEHI) Working Group developed the EHS Strategy “to accelerate progress in research to protect public health and the environment, and to fill gaps in, and -- with the growing level of effort worldwide -- to avoid unnecessary duplication of, such research.”

CRS Report Reviews Possible Risk Management Approaches for Congress to Consider

According to a January 22, 2008, Congressional Research Service (CRS) report entitled Engineered Nanoscale Materials and Derivative Products: Regulatory Challenges, questions about the need for, and ideal form of, nanotechnology regulations are “exceedingly difficult” to address, given the current state of scientific understanding. CRS considered challenges faced by scientists, entrepreneurs, and agency officials involved in the National Nanotechnology Program as they work to define the characteristics of nanomaterials; the environmental, human health, and safety (EHS) risks they might pose; and how any potential risks should be addressed. The report states that challenges include the wide variety of nanomaterials and applications; lack of basic information about their properties; lack of conventions for naming, measuring, and identifying nanomaterials; the proprietary nature of some critical information; the need to prioritize federal resource needs; and a possible lack of clear statutory authority or appropriate regulatory framework to anticipate or respond to any identified risks. CRS states that, should Congress choose to intervene, it might choose any of several approaches: increasing funding for workshops in standardization or other research relevant to identifying and possibly ameliorating any EHS concerns associated with nanomaterials; changing the allocation of research money among agencies or the interagency research management structure; adopting a national or international research strategy; or enacting legislation that authorizes, mandates, or constrains agency actions to require information collection or to restrict production, sale, use, or disposal of nanomaterials.

DEFRA Publishes Research Report On Manufactured Nanomaterials

On December 19, 2007, the Department for Environment, Food and Rural Affairs (DEFRA) published a report entitled Characterising the Potential Risks Posed by Engineered Nanoparticles: A Second UK Government Research Report, which follows up on DEFRA’s 2005 report and 2006 progress report. The report reviews the status of research pertaining to the environmental, health, and safety (EHS) issues relating to engineered nanoparticles, and places the United Kingdom’s (UK) research program in an international context. DEFRA is collaborating with international partners, particularly the Organization for Economic Cooperation and Development (OECD) and the International Standards Organization (ISO), to share data and experiences. In this way, according to the report, DEFRA will be able to maximize the effectiveness and speed with which potential risks may be identified and managed.

EHS Research Priorities Released for Comment

On August 16, 2007, the National Nanotechnology Coordination Office (NNCO), on behalf of the Nanoscale Science, Engineering, and Technology (NSET) Subcommittee of the Committee on Technology, National Science and Technology Council (NSTC), published a notice in the Federal Register announcing the availability of a document entitled The Prioritization of Environmental, Health, and Safety Research Needs for Engineered Nanoscale Materials: An Interim Document for Public Comment, which assigns priority to research needs and areas identified in the NSET Subcommittee document Environmental, Health, and Safety Research Needs for Engineered Nanoscale Materials, which was published on September 21, 2006.  Comments are due September 17, 2007.

The document identifies 25 priority research needs across five research categories.  The needs are listed from highest to lowest priority for each category, with the exception of those presented in the category Nanomaterials and Human Health.  The Nanomaterials and Human Health Task Force gave equal weight to identified research needs under an overarching research priority for the category.

Senate Requests GAO Review of NNI

In a March 15, 2007, letter, the Senate Committee on Commerce, Science, and Transportation and the Congressional Nanotechnology Caucus requested that the Government Accountability Office (GAO) review the National Nanotechnology Initiative (NNI), which was created to accelerate the discovery, development, and deployment of nanoscale science and technology. For fiscal year 2006, NNI received $1.2 billion in research and development funding, and 22 federal agencies, including the U.S. Environmental Protection Agency (EPA), the Food and Drug Administration (FDA), the Consumer Product Safety Commission (CPSC), and the Occupational Safety and Health Administration (OSHA), participate in NNI. According to the letter, one key expectation for NNI was “to ensure that adequate attention and research funding was made available to gain a better understanding of the potential environmental, health, and safety (EHS) risks associated with nanomaterials.” The letter states that the Committee and Caucus “are extremely concerned that this has not happened and that there is a lack of transparency with regard to how much federal attention and funding this important aspect of the initiative is receiving.”

To determine the extent to which federal agencies have undertaken EHS research and how they are prioritizing and managing this research, the Committee and Caucus ask GAO to:

  •  Review the extent to which NNI-related resources have been devoted to study the EHS risks of nanomaterials;
  • Identify the key areas of research for which this EHS funding has been used;
  • Determine what processes the Nanotechnology Environmental and Health Implications Working Group uses to prioritize and coordinate these various EHS research efforts; and
  • Review and identify any EHS-related research and regulatory activities, independent of the NNI, that EPA, FDA, CPCS, and OSHA have undertaken, the amount of funding made available for these efforts, and the extent to which information about these efforts has been communicated to the Working Group to ensure that they are considered in the overall research planning processes for the NNI.
