NIOSH Publishes Technical Report on Occupational Exposure Sampling for Engineered Nanomaterials
On July 29, 2022, the National Institute for Occupational Safety and Health (NIOSH) published a Technical Report: Occupational Exposure Sampling for Engineered Nanomaterials. Since 2010, NIOSH has developed guidance for workplace sampling for three engineered nanomaterials: carbon nanotubes (CNT) and nanofiber (CNF), silver, and titanium dioxide, each of which has an elemental mass-based NIOSH recommended exposure limit (REL). NIOSH has also developed a practical approach to...
