Technical Report: Occupational Exposure Sampling for Engineered Nanomaterials

Posted On: 2022-08-10

NIOSH developed guidance for workplace sampling for three engineered nanomaterials: carbon nanotubes and nanofibers, silver, and titanium dioxide, each of which have an elemental mass-based NIOSH Recommended Exposure Limit (REL). In addition, NIOSH developed a practical approach to exposure sampling for other engineered nanomaterials that do not have exposure limits.
