ENVIRONMENTAL, HEALTH, AND SAFETY RISKS ASSOCIATED WITH NANOTECHNOLOGY

Their small sizes enable nanomaterials to express novel properties that have created a revolution in science and technology since their discovery in the 1990s. The new transport, morphology and material properties of nano-enabled products, however, have imposed revision of environmental, health, and safety risk assessments and management concepts previously established for conventional materials. At the current stage of nanotechnology development, uncertainties still exist due to the inability to adequately quantify and characterize nano-enabled products properties in complex matrices, including living organisms and the environment. The multidisciplinary effort is required for the development of analytical tools and methods that provide answers to multiple nanomaterial-related properties and help explicate the property exposure and property-hazard relationships from a life cycle perspective.
