Risks Assessment and Management of Nanotechnology

Studies of the health effect of airborne particles usually shown that for toxic materials, smaller particles are more toxic. This is due in part to the fact that, the same mass per volume, the dose in terms of constituent part numbers rises as particle size decreases. Based on available data, it has been claimed that current risk assessment methods are not suited to the hazards related with nanoparticles; in particular, existing toxicological and eco-toxicological procedures are not up to the task; exposure evaluation needs to be conveyed as quantity of nanoparticles and surface area relatively than simply mass; tools for routine detecting and evaluating nanoparticles in air, water, soil is inadequate; and very tiny is known about the physiological replies to nanoparticles. Regulatory bodies in the U.S. as well as in the EU have determined that nanoparticles form the potential for a completely new risk and that it is essential to carry out an extensive study of the risk. The challenge for regulators is whether a matrix can be advanced which would recognize nanoparticles and more complex Nano-formulations which are expected to have special toxicological properties or whether it is more practical for each particle or formulation to be tested separately.
