One of the biggest challenges is managing environmental, health and safety risks of nanomaterials. Yet, the information necessary to assess their long term effects is scarce. The second International Symposium, 2005, Minneapolis, Minnesota, with many more attendants than the first, and with contributions from academics, industry, policymakers, non-government organizations and even lawyers, established that, while there is international concern over how to ensure safe nanotech-workplaces, there is also progress being made in developing the required knowledge. This volume, a reprint from a special issue of the Journal of Nanoparticle Research, mainly draws from work presented at the 2005 symposium, diverse but united by the need for a holistic view of nanotechnology and risk.

Nanotechnology is rapidly invading many aspects of modern society - from science, research and engineering to industrial and commercial applications and, inevitably, to man and his environment. One of the biggest challenges, therefore, is managing environmental, health and safety risks of nanomaterials. Yet, the information necessary to assess their long term effects is scarce. Systematic research into what potentially makes engineered nanomaterials hazardous, how this translates into risk, and how these can be managed will be vital and involves interdisciplinary collaboration.

The first International Symposium on Nanotechnology and Occupational Health, in 2004, brought together hygienists, manufacturers, toxicologists, materials scientists, regulators and researchers. It pointed the way to what needs to be done. The second International Symposium, 2005, Minneapolis, Minnesota, demonstrated the power and potential where there is a will: with nearly three times as many attendants, and with contributions from academics, industry, policymakers, non-government organizations and even lawyers, this second symposium established that, while there is international concern over how to ensure safe nanotech-workplaces, there is also progress being made in developing the required knowledge.

This volume, a reprint from a special issue of the Journal of Nanoparticle Research, mainly draws from work presented at the 2005 symposium, diverse but united by the need for a holistic view of nanotechnology and risk.

As scientists and technologists discover how to engineer matter at the nanoscale in increasingly sophisticated ways, conventional approaches to ensuring safe use are being brought into question. Nanotechnologies are challenging traditional regulatory regimes; but they are also prompting new thinking on developing and using emerging technologies safely. In this Handbook, leading international authors from industry, government, non-governmental organisations and academia examine the complex and often controversial regulatory challenges presented by nanotechnologies. Across several disciplinary boundaries, they explore how the future regulatory landscape may evolve. From the Europe Union to the United States, workplaces to personal products, and statutory instruments through to softer approaches, it is clear that considerable vigilance will be needed in governing these powerful and novel technologies. To succeed, society will need new thinking, new partnerships and new mechanisms to balance the benefits of these technologies against their possible downsides. Anything less will prompt cries of illegitimacy and potentially compromise a promising new realm of technology innovation.
