Nanotechnology: Human and Environmental Exposure Assessment of Nanomaterials Workshop

Because of the relative newness of nanotechnology, very little exposure data have been reported in the scientific literature. At this stage, measuring or determining risk becomes a little like trying to solve a mystery when major clues are missing. Scientists and engineers face this challenge even as the market for nanotechnology grows, and along with it, an increasing demand from diverse parties for guidance to underpin its responsible development. Read More >

Persistent Pulmonary Fibrosis, Migration to the Pleura, and Other Preliminary New Findings after Subchronic Exposure to Multi-Walled Carbon Nanotubes

Multi-walled carbon nanotubes (MWCNTs) are a type of engineered nanomaterial that shows promise for creating stronger, more durable building materials; improving cancer therapies; creating more efficient means of energy generation, storage, and transmission; and speeding computer processes. However, as with other types of engineered nanomaterials, the potential occupational health implications of MWNCTs are not well understood at this emergent stage of the technology. Read More >

Nanotechnology: Should carbon nanotubes be handled in the workplace like asbestos?

Do the nanoparticles used in nanotechnology pose unintended risks of illness or injury for workers employed in the industry? The NIOSH Science Blog looks at one nanomaterial—carbon nanotubes—and discusses new research findings about their similarities to asbestos and how they should be handled in the workplace to protect workers. Read More >
