House of Lords Committee Releases Report on Nanotechnologies and Food

On January 8, 2010, the United Kingdom (UK) House of Lords Science and Technology Committee announced the availability of its report entitled Nanotechnologies and Food, which criticizes the food industry for failing to be transparent about its research into the uses of nanotechnologies and nanomaterials. In its report, the Committee urges the Government and Research Councils to fund research into potential health and safety risks arising from the use of nanomaterials in the food sector. The Committee recommends that the Food Standards Agency maintain a publicly available register of food and food packaging containing nanomaterials, and suggests that the register be made available online. The Committee calls for nanomaterials to be defined clearly in food legislation to ensure that all uses of nanomaterials in food are subject to appropriate risk assessment procedures. According to the Committee, regulatory definitions should use a change in functionality, i.e. how a substance interacts with the body, as the criterion that distinguishes a nanomaterial from its larger form, to ensure that any nano-sized materials with novel properties are included. The Committee also recommends that the UK work with other European Union (EU) nations to clarify what is meant by the phrase “properties that are characteristic to the nanoscale” in the draft definition proposed for the revised Novel Foods Regulation, by the inclusion in legislation of a more detailed list of what these properties comprise. The Committee also raises concerns about the potential for the illegal importation of food products containing nanomaterials not approved for use in food in the EU.

UK Will Develop Strategy for Nanotechnologies

On June 2, 2009, the United Kingdom (UK) released its response to the Royal Commission on Environmental Pollution (RCEP) Report entitled Novel Materials in the Environment: The Case of Nanotechnology. The RCEP looked at the properties of nanomaterials and the potential pathways by which they could enter and present potential hazards to the environment and people. The UK states that it shares RCEP’s “understanding that there is no evidence of actual harm resulting from the use of nanotechnologies, but accepts that this is a possibility and that there is a need to develop our understanding further.” The UK intends to develop a “UK Strategy for nanotechnologies,” which “will build on previous and existing activities and review the UK’s priorities and strategic direction.” The UK intends to begin in Summer 2009 an “evidence gathering exercise” with stakeholders to inform development of the Strategy.

EPA Seeks Joint Applications from U.S. and UK Partners Regarding Nano Research

On March 31, 2009, the U.S. Environmental Protection Agency (EPA) announced the funding opportunity for its joint U.S. -- United Kingdom (UK) Research Program: Environmental Behavior, Bioavailability, and Effects of Manufactured Nanomaterials. EPA states that the outputs of the Program will be used to further scientific understanding of the fate, behavior, bioavailability, and effects of nanomaterials and risk management policy development. Two consortia, made up of UK and U.S. research institutions, will be selected for funding. EPA is seeking joint applications from U.S. and UK partners that:

  • Propose integrated model(s) of fate, behavior, bioavailability and effects for several important and representative nanomaterial classes over key environmental pathways using intrinsic material properties and life cycle analysis as a starting point for model development;
  • Validate and refine these model(s) through interdisciplinary research, addressing key assumptions and areas of uncertainty; and
  • Develop effective methods and tools to detect, assess, and monitor the presence of nanomaterials in biological and environmental samples.

HSE Publishes Information Sheet Regarding the Risk Management of CNTs

On March 6, 2009, the United Kingdom (UK) Health and Safety Executive (HSE) published an information sheet on the risk management of carbon nanotubes (CNT). According to HSE, the information sheet “is specifically about the manufacture and manipulation of carbon nanotubes and has been prepared in response to emerging evidence about the toxicology of these materials. However, the risk management principles detailed here are equally applicable to other nanodimensioned bio-persistent fibres with a similar aspect ratio.” HSE cites as “new evidence” a recent study by the University of Edinburgh, which “found that long, straight [multi-walled CNTs] with a high aspect ratio produced a marked inflammatory reaction and the formation of granulomas when injected into the abdominal cavity of mice.”

HSE states:

HSE views CNTs as being substances of very high concern. Although the recent findings only apply to some CNTs, we think a precautionary approach should be taken to the risk management of all CNTs, unless sound documented evidence is available on the hazards from breathing in CNTs. If their use cannot be avoided, HSE expects a high level of control to be used.

The information sheet includes specific recommendations for risk management. According to the information sheet, waste CNTs “should be classified and coded as hazardous waste.”

 

EPA Announces Joint Research Partnership with UK Agencies Regarding the Behavior and Effects of Nanomaterials in the Environment

On December 29, 2008, the U.S. Environmental Protection Agency (EPA) announced that it is in the process of finalizing a major joint research effort with a number of United Kingdom (UK) agencies that is intended to develop and validate predictive tools and similar conceptual models that predict exposure, bioavailability, and effects of manufactured nanomaterials in the environment. The UK agencies include the Natural Environment Research Council, Engineering and Physical Sciences Research Council, Department for Environment, Food, and Rural Affairs, and Environment Agency.  According to EPA, the research partnership will include a joint call issued by all organizations involved and will incorporate a common review and evaluation process.  EPA states: “The intent is to form consortia of both UK and US investigators using combined but independent national funding arrangements.” EPA expects the solicitations to be issued in February 2009.

UK RCEP Releases Latest Report on Nanotechnology

On November 12, 2008, the United Kingdom (UK) Royal Commission on Environmental Pollution (RCEP) published a report entitled Novel Materials in the Environment: The Case of Nanotechnology, which examines issues related to innovation in the materials sector and the challenges and benefits arising from the introduction of nanomaterials. According to RCEP, there is an “urgent need for more testing, extending existing governance arrangements and creating new arrangements concerning nanomaterials.”  The report was prompted by concerns about potential releases to the environment from industrial applications of metals and minerals that have not previously been widely used. The RCEP states that, as the majority of the evidence it received was almost entirely focused on manufactured nanomaterials, it decided to focus on this sector as an exemplar. The report includes recommendations on how to address “ignorance and uncertainty in this area, which could also be applied to other areas of fast-paced technological development.”

The RCEP’s recommendations reflect three main priorities:

  • Functionality: The need to focus on the properties and functionalities of specific nanomaterials as the key driver for understanding their behavior in organisms and the environment, rather than treating all materials in the size range as one single class;
  • Information: A directed and substantial research program on the properties and functionalities of nanomaterials must be established as a matter of urgency, to inform risk assessment and risk management strategies. One essential part of such a directed program will be the development of techniques that allow the presence of particular nanomaterials to be detected in the environment; and
  • Adaptive management: Government urgently needs to recognize the degree of ignorance and uncertainty in this area, and the time it will take to address these. Government needs to develop flexible and resilient forms of management that allow appropriate control of emergent technologies in general, and for nanomaterials in particular.

 

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.

UK Publishes First Bulletin on Nanotechnology Research

On May 11, 2007, the United Kingdom (UK) Health & Safety Executive (HSE) published its first bulletin on nanotechnology research. The bulletin is intended to provide an overview of published studies that have examined the exposure and potential health effects of nanomaterials, particularly in the occupational setting. According to HSE, inevitably there will be some overlap between studies of exposure of other groups (i.e. consumers).  HSE screened the literature search results to ensure that the studies listed are relevant to HSE and its responsibility to manage health and safety in the workplace. The first bulletin reviews literature published in 2000-2006. According to HSE, subsequent bulletins will summarize publications from the previous four-month period. The bulletins will summarize the range of studies that have been published in two areas of interest: measurement, characterization, and control of exposure to nanoparticles; and potential for toxic effects of nanoparticles in humans.
