Scientific strategies for predicting risks and hazards associated with nanomaterials

Abstract

For the move from nanoscience to nanotechnology to be sustainable, it is important that the issues surrounding possible 'nano-hazards' be addressed before commercialization. In the case of nanomaterials, many hazardous characteristics can ultimately be traced back to the reactivity of individual nanoparticles. Unfortunately, reactivity may vary depending upon size, shape, degree of agglomeration, and the chemical and thermal environment. Hence, the task of testing all possible permutations, for all the different nanoparticles in production, is fast becoming unfeasibly large. In addition to this, there is a current (global) push for more environmentally friendly, bio-degradable products. It is therefore valid to assume that the introduction of the nanoparticles in these product into the ecosystem is an inevitability. When this happens it is desirable to know how the hazardous properties may be affected, and what the risks are. In this chapter a number of strategies will be discussed, combining the desirable aspects of theory, simulation, experiment and observation, and leading to predictions for incorporation into preventative frameworks. Particular attention will be given to the role of scientific research, and how it intersects with the participants from complementary fields. Show more
