Project Scope


  • 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.

Milestones

  • 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.

Outputs

  • 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)

Outcomes

  • 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.
