All major government environmental, health and safety regulations, like TSCA, were designed before the emergence of nanotechnology -- the ability to measure, see, manipulate, and manufacture things at an atomic and molecular scale, usually between 1 and 100 nanometers. A nanometer is one billionth of a meter; a human hair is roughly 100,000 nanometers wide.
In a nano marketplace, are existing oversight mechanisms adequate or do they need to be reassessed and changed? Does it make sense to consider a new law? Does government have the necessary human and financial resources to anticipate and manage the possible health and environmental implications of nanotechnology? Are there incentives to speed nanotechnology applications for environmentally beneficial uses? Davies' report examines these and other questions.
