    In this report we present the findings from a nanotoxicology workshop held 6–7 April 2006 at the Woodrow Wilson International Center for Scholars in Washington, DC. Over 2 days, 26 scientists from government, academia, industry, and nonprofit organizations addressed two specific questions: what information is needed to understand the human health impact of engineered nanoparticles and how is this information best obtained? To assess hazards of nanoparticles in the near-term, most participants noted the need to use existing in vivo toxicologic tests because of their greater familiarity and interpretability. For all types of toxicology tests, the best measures of nanoparticle dose need to be determined. Most participants agreed that a standard set of nanoparticles should be validated by laboratories worldwide and made available for benchmarking tests of other newly created nanoparticles. The group concluded that a battery of tests should be developed to uncover particularly hazardous properties. Given the large number of diverse materials, most participants favored a tiered approach. Over the long term, research aimed at developing a mechanistic understanding of the numerous characteristics that influence nanoparticle toxicity was deemed essential. Predicting the potential toxicity of emerging nanoparticles will require hypothesis-driven research that elucidates how physicochemical parameters influence toxic effects on biological systems. Research needs should be determined in the context of the current availability of testing methods for nanoscale particles. Finally, the group identified general policy and strategic opportunities to accelerate the development and implementation of testing protocols and ensure that the information generated is translated effectively for all stakeholders

    Promoting good practices for handling nanomaterials : an international wiki project

    No full text
    As production and use of nanomaterials in commercial products grow it is imperative to ensure these materials are used safely with minimal unwanted impacts on human health or the environment. Foremost among the populations of potential concern are workers who handle nanomaterials in a variety of occupational settings, including university laboratories, industrial manufacturing plants and other institutions. Knowledge about prudent practices for handling nanomaterials is being developed by many groups around the world but may be communicated in a way that is difficult for practitioners to access or use. The GoodNanoGuide is a collaborative, open-access project aimed at creating an international forum for the development and discussion of prudent practices that can be used by researchers, workers and their representatives, occupational safety professionals, governmental officials and even the public. The GoodNanoGuide is easily accessed by anyone with access to a web browser and aims to become a living repository of good practices for the nanotechnology enterprise. Interested individuals are invited to learn more about the GoodNanoGuide at http://goodnanoguide.org
