Task 1. Optimization of the magnetic passive aerosol sampler (MPAS) design - evaluating MPAS efficiency under various conditions and interferences, and comparison with reference samplers.
Task 2. Development and validation of a standardized bench-scale particulate penetration test method.
Q1 Optimize uniformities of both wind velocity and particle size distribution inside the wind tunnel recirculation aerosol chamber.
Q2 Complete MPAS performance evaluation under different operational conditions, including the effects of iron oxide particle size and upstream wind velocity.
Q3 Finalize a deposition velocity model for the MPAS.
Q4 Submit two manuscripts on MPAS for internal peer review.
Manuscripts published or submitted to peer review journals (2)
Presentations at conferences (6)
This project has resulted in two employee invention reports
This project has contributed to a book chapter on Selection of PPE to protect against nanoparticle dermal exposure (in Press)
This project has contributed to the PPE section in Chapter 4 of the NIOSH NTRC document titled "Progress toward Safe Nanotechnology in the Workplace" and the NTRC report titled "Approaches to Safe Nanotechnology: An Information Exchange with NIOSH" .
This project has resulted in a new research proposal entitled "Nanoparticle penetration through protective clothing", which was funded by NIOSH NTRC and the study has been completed.
Improved standards and test methods for protective clothing used for protection against inert and biological aerosols.
