(Funded by the National Institute for Occupational Safety and Health)
The National Institute for Occupational Safety and Health’s Nanotechnology Research Center (NTRC) is celebrating its 20-year anniversary! Over the years, researchers at the NTRC have studied the #toxicity of many engineered nanomaterials throughout their life cycles. The research has covered primary manufactured forms (such as carbon nanotubes, nanoscale titanium dioxide, and silver nanoparticles) and modified versions for specific applications (such as silica-coated iron oxide, heat-treated carbon nanotubes, and reduced graphene oxide). Early studies focused on the tiniest components of air pollution, known as ultrafine particles, which laid the foundation for ongoing research efforts to assess two types of nanoparticles found in workplaces: engineered nanomaterials (purposely created for various applications) and process-derived nanoparticles (unintentionally produced during industrial processes). Also, using samples from worker health effects studies, researchers developed toxicology studies to determine biomarkers of exposure and disease. Together, these studies offer valuable data for understanding workplace hazards and risks.
