Too much data, too little context

Those of us who have been working in nanotechnology since the beginning of the decade have witnessed the remarkable growth and evolution of research into engineered nanomaterials' environmental, health and safety impacts. In 2001, there were virtually no papers addressing the impacts of intentionally manufactured nanomaterials.

Fast forward to now. This graph shows the explosive growth of research papers covering aspects of nano-EHS between 2001 and 2008. In a few short years we've gone from no data to, one could argue, too much data. Too much data, you say? Then explain why every newspaper article and policy report I read on the subject ends up saying basically the same thing: we still don't know enough about engineered nanomaterials to quantify risks.

The reasons are myriad and include the slow development and acceptance of standards for toxicity testing, materials characterization and even terminology; the dearth of validated protocols for testing; and other ripples of the culture clash that ensued when materials scientists, aerosol physicists, environmental engineers, and toxicologists all started to learn to collaborate.

People who have witnessed the emergence of other interdisciplinary fields of inquiry could have told us it would take some time to work out and then propagate the best research practices. But there seems to be a special urgency to nano-EHS research as governments, NGOs, companies, attorneys and other interested parties grapple with how this body of data should be used to inform decision-making. The various "solutions to the nano-EHS issue" being bandied about, including regulation, insurance policies, voluntary codes, risk markets, etc., all rely upon good quality data that is interpreted correctly. Journalists need to get a feel for what a reasonable community of experts thinks about this or that new paper that demonstrated the hazards of a particular nanomaterial in a particular laboratory experiment.

In short, context and analysis are critical.

Once upon a time, ICON thought it could provide this context and, indeed, we've produced a few backgrounders that review and analyze hot topics in nano-EHS. But this function is best performed by the community at large, those of you who are also wrestling with questions about choice of medium, dose, exposure route, particle sizing technique and other minutiae of life in the lab.

Starting this week, the ICON Virtual Journal aims to provide you the opportunity to shape future nano-EHS research practice by commenting on papers in our database. Despite an overwhelmingly positive response to this idea from people we surveyed during the conception and development phase, there remains some discomfort with the idea of people passing judgment on papers that have already passed through peer review. (Because we all know the peer review process is perfect.) Here are the top two reasons your peers gave for wanting this rating system:
  • Papers of high quality should be recognized so they can serve as models for other researchers in this field
  • This will help journalists, the public and other lay audiences know which research is the best, which will inform the public dialogue over nano’s risks and benefits
Now what could be wrong with recognizing papers of outstanding quality so that the field as a whole gravitates toward the best practices and people on the outside understand the implications of new work? Yes, yes, we still have issues to work out with respect to standards, etc. but in addition to giving a snapshot of where the field is now, the ratings could actually advance the discussion of best practices and broaden it to include underrepresented voices. "You may say I'm a dreamer. But I'm not the only one."

Unless you're a troll, I invite you to register at the site and rate 5 papers with which you are very familiar. Then email 10 colleagues and encourage them to do the same. (Start with the cranky ones who are always griping to you about the @#^% that gets published these days in the vanity journals.) Choose a non-identifying username if you want (students seeking future employment) or publish under your own name as a way of demonstrating how smart and thoughtful you are (consultants, tenured professors). Either way, we'll be able to pull inappropriate content off the site as needed.

Safety Professionals Give Warm Reception to GoodNanoGuide

The American Industrial Hygiene Association held its annual meeting this year in Toronto with a theme of Discoveries Beyond Borders. After the Monday morning keynote address by Dr. Peter Diamandis, chairman and CEO of the X PRIZE Foundation, the next two keynotes were on issues AIHA has identified as “two major challenges in the field: sustainability and nanotechnology.” Addressing the issue of sustainability was Edward L. Quevedo, JD, special counsel chair for the sustainability group at Farella Braun and Martel. (An interview with Mr. Quevedo about his keynote is posted here.)

My talk kicked off Wednesday’s focus on nanotechnology. Before and after the keynote talk I was able to hang out at NIOSH’s exposition booth where I was graciously provided an internet-connected computer on which to live-demo the GoodNanoGuide to passersby. But the invitation to speak before a crowd of about 1000 occupational safety professionals provided an ideal opportunity to formally launch the GoodNanoGuide, an international online collaborative wiki designed to create a forum for people seeking to work with engineered nanomaterials safely. The format of the keynote address did not allow for questions, so AIHA set aside a separate time and place for an “Ask the Expert” session later on Wednesday morning. This session was attended by about a hundred people and we eschewed the formal structure of me sitting up on a dais for a more informal conversational mode. This involved me running up and down the aisles passing the microphone back and forth among the questioners, myself and others in the audience better equipped to answer a given question. (Most times, this was Chuck Geraci, Laura Hodson or Donna Heidel from NIOSH who could report on specific research being done at the institute to inform occupational practice.)

Feedback to the talk and to the GoodNanoGuide was positive and we noted a major spike in visits to the site during the meeting. But even more importantly, we are already beginning to field requests to join the GoodNanoGuide community. (We map their locations here.) This is vital because the site will only grow into the knowledge base we all want it to become if a diverse and robust community of experts contributes. Join us by visiting the GoodNanoGuide here and registering as a contributor.
