Nanotechnology promises to have far reaching impacts on the economy, including offering technological advances in pollution control. While over 200 products that use nanomaterials are already in the marketplace, minimal data exist on the health and environmental effects of nanomaterials. This poses significant questions for companies, regulators, consumers, and lawyers. The "Nanotechnology Deskbook" guides the reader through the application of existing law and regulations to nanomaterials by exploring domestic laws and regulations and considering developments in the international context. It includes a focus on special business considerations when this technology is involved and concludes by discussing the development of an effective environmental governance structure for nanotechnologies that protects human health and the environment without stifling the development of this new field.
