NIOSH Risk Assessment of Engineered Nanomaterials

The National Institute for Occupational Safety and Health (NIOSH) is celebrating the 20th anniversary of the NIOSH Nanotechnology Research Center (NTRC)! This blog post from NIOSH highlights NTRC activities in risk assessment of engineered nanomaterials. The small size of engineered nanomaterials (at least one dimension smaller than 100 nanometers) gives them unique and useful properties, but they could also pose a health risk to workers who produce or use these materials. NIOSH conducts risk assessments to estimate the likelihood and severity of adverse health effects in workers exposed to chemical substances, including nanomaterials. NIOSH risk assessments support the development of occupational safety and health recommendations.
