Current Intelligence Bulletin 60: Interim Guidance for Medical Screening and Hazard Surveillance for Workers Potentially Exposed to Engineered Nanoparticles

The potential occupational health risks associated with the manufacture and use of nanomaterials are not yet clearly understood. Many engineered nanomaterials and devices are formed from nanometer-scale particles (i.e., nanoparticles) that are initially produced as aerosols or colloidal suspensions. Exposure to these materials during manufacturing and use may occur through inhalation, dermal contact, or ingestion; however, inhalation exposure is the main route of concern [ASCC 2006]. There is very limited information available about dominant exposure routes, the potential for exposure, and material toxicity.
