Controlling Exposures to Workers Who Make or Use Nanomaterials

  Background It is difficult to estimate how many workers are involved in this field. By one estimate, there are 400,000 workers worldwide in the field of nanotechnology, with an estimated 150,000 of those in the United States [Roco et al. 2010]. The National Science Foundation has estimated that approximately 6 million workers will be Read More >

New Findings on Lung Tumor Formation in Laboratory Mice Exposed to Multi-Walled Carbon Nanotubes

Earlier today, at the annual meeting of the Society of Toxicology, NIOSH researchers reported preliminary findings from a new laboratory study in which mice were exposed by inhalation to multi-walled carbon nanotubes (MWCNT).  The study was designed to investigate whether these tiny particles have potential to initiate or promote cancer.  By “initiate,” we mean the Read More >

Safe Handling of Advanced Nanomaterials

In the last five years, research and development activities in the field of nanotechnology have shifted to include advanced nanomaterials. The main feature of advanced nanomaterials that distinguishes them from simpler nanomaterials, such as carbon black and nanoscale TiO2 used primarily as additives, is the ability of advanced nanomaterials to change or evolve properties during Read More >
