| This research evaluated and analyzed handling of nanomaterials (NMs) during standard laboratory weighing and sample preparation procedures. Activity-based real-time sampling was employed to evaluate potential exposure to NM particles by researchers working in an academic laboratory and focused on laboratory-scale activities in an academic research environment.;This study showed that for the processes being evaluated, the production of particulate and/or aerosol was dependent on the activity. It is therefore recommended that activity-based monitoring be used when developing protocols for assessing inhalation hazards in laboratories working with NMs.;As this information improves over time, this sampling procedure's effectiveness in setting protocols for working with NMs in a research environment could change. The findings are of value for the continuing development of best practices in NMs safety, disposal, and product stewardship, as well as a basis for ongoing research in the management of NMs in an academic laboratory environment. |
