OECD Publishes Analysis of Survey on Consumer and Environmental Exposures to Manufactured Nanomaterials

Posted in International, OECD, Research

The Organization for Economic Cooperation and Development published a November 7, 2017, report entitled Consumer and Environmental Exposure to Manufactured Nanomaterials — Information used to characterize exposures:  Analysis of a Survey.  The report provides a “light analysis” of the results of a Working Party on Manufactured Nanomaterials (WPMN) survey on consumer and environmental exposures to manufactured nanomaterials.  The survey, initiated in 2015, was designed to collect information used to characterize consumer and environmental exposures for human and ecological risk assessment.  WPMN intended the survey to be used as a tool to inform potential avenues for future research and collaboration in the area of exposure assessment as it relates to manufactured nanomaterials.  The survey collected data on the importance and availability of information and data in six broad categories:  (1) material characterization; (2) production, use, and market; (3) releases to the environment (direct, indirect, and via consumer use); (4) environmental fate and transport; (5) exposure assessment (direct and indirect); and (6) exposure control and mitigation.  The report presents an analysis of the survey data within each of these categories and highlights the importance of multiple types of information, ranging from material characterization to environmental release and exposure analysis.  The report also contains a more detailed analysis of the issues in each of the six categories, with respect to perceived importance, data availability, and framework.  The report recommends potential avenues for future work by the OECD; these are grouped into the following three themes, based on linkages identified by the survey:

  • Theme 1 includes projects related to the development and use of exposure models for manufactured nanomaterials. This includes information on production/import quantities, exposure pathways, and exposure measurement in the environment, for consumers and of emissions from consumer articles and products;
  • Theme 2 includes projects on issues related to environmental behavior and transformation, and includes information on nanomaterials released from the use of articles and products to the environment; and
  • Theme 3 includes projects related to the material characterization of manufactured nanomaterials and includes data on the physical form of nanomaterials in products.

According to the report, recommended next steps include obtaining feedback on the direction proposed for future OECD projects and identifying specific projects that can be undertaken by WPMN.  Follow up on selected survey responses is also recommended to determine the feasibility and applicability of data for future activities

BfR Publishes Q&A Regarding Study on Fate and Effects of Tattoo Pigments in Human Skin

Posted in EU Member State, International, Research

On October 12, 2017, the German Federal Institute for Risk Assessment (BfR) published questions and answers (Q&A) regarding a study on whether nanometric pigments from tattoo inks can permanently accumulate in lymph nodes.  BfR states that by using X-rays from a particle accelerator in Grenoble, it discovered where the pigments accumulate in the tissue.  According to BfR, until now, the accumulation of pigments from tattooed persons has been known by optical coloring of the lymph nodes only, as they often had been of the same color as the tattoo.  Both skin and lymph nodes have now been characterized in terms of their chemical composition, pigment identity, and size.  The study, “Synchrotron-based ν-XRF mapping and μ-FTIR microscopy enable to look into the fate and effects of tattoo pigments in human skin,” was published in September 2017.

UK Parliamentary Office Publishes Note on Risk Assessment of Nanomaterials

Posted in International, Legal/Regulatory Issues

On October 5, 2017, the United Kingdom’s (UK) Parliamentary Office of Science and Technology (POST) published a POSTnote entitled “Risk Assessment of Nanomaterials.”  According to POST, key points include:

  • Nanomaterial uses and benefits are diverse and increasing, such as in cosmetics, textiles, electronics, and medicine;
  • Current regulatory frameworks applicable to nanomaterials within the UK are mainly set at the European Union (EU) level;
  • There are some indications of potential health and environmental risks, but conclusions are limited by insufficient long-term evidence and difficulties in translating results from the laboratory to the real world;
  • Post-Brexit, the UK will need to establish regulatory frameworks for nanomaterials; and
  • The wide range of forms and uses of nanomaterials present many regulatory challenges, such as ensuring consistency in testing and finding valid ways of grouping nanomaterials so that their risks may be assessed more efficiently.

 

ISO Publishes Standard on Use and Application of Acellular In Vitro Tests and Methodologies to Assess Nanomaterial Biodurability

Posted in International, Research

In October 2017, the International Organization for Standardization (ISO) published standard ISO/TR 19057:2017, “Nanotechnologies — Use and application of acellular in vitro tests and methodologies to assess nanomaterial biodurability.”  The standard reviews the use and application of acellular in vitro tests and methodologies implemented in the assessment of the biodurability of nanomaterials and their ligands in simulated biological and environmental media.  It is intended to focus more on acellular in vitro methodologies implemented to assess biodurability and, therefore, excludes the general review of relevant literature on in vitro cellular or animal biodurability tests.

OECD Report Examines How to Determine Concentrations of Manufactured Nanomaterials in Workplace Air

Posted in International, Occupational Health and Safety Issues, OECD, Research

The Organization for Economic Cooperation and Development (OECD) has posted an October 30, 2017, report entitled Strategies, Techniques and Sampling Protocols for Determining the Concentrations of Manufactured Nanomaterials in Air at the Workplace.  The objective of the report is to contribute to existing knowledge regarding methods for measuring characteristics of airborne nanoparticles and controlling occupational exposure to airborne nanoparticles, and to gather data on nanoparticle emission and transport in various workplaces.  The report includes the findings of research undertaken in non-industrial nanotechnology workplaces involving the measurement of nanomaterials emissions and exposures.  It presents six case studies that demonstrate how measurement and assessment of nanomaterials can be undertaken and how results can be interpreted:  grinding and extrusion of modified titanium dioxide; manufacture of clay-polyurethane nanocomposite material; grinding of titanium dioxide powder; jet milling of modified clay particles; decanting of single- and multi-walled carbon nanotubes; and synthesis of carbon nanotubes using chemical vapor deposition.  The report notes that “it is worth mentioning that this document contributed to the development of the document ‘Harmonized Tiered Approach to Measure and Assess the Potential Exposure to Airborne Emissions of Engineered Nano-Objects and their Agglomerates and Aggregates at Workplaces’ published as No.55 in the OECD Series on the Safety of Manufactured Nanomaterials [ENV/JM/MONO(2015)19].”
