Task 1. Optimization of the magnetic passive aerosol sampler (PAS) design - evaluating PAS efficiency under various conditions and interferences, numerical simulation, and comparison with reference samplers.
Task 2. Development and validation of a standardized bench-scale particulate penetration test method.
Q1 Built a new aerosol chamber that is able to create wind speeds up to 10 miles/hr for evaluating particle penetration through clothing materials using magnetic aerosol samplers
Q2 Evaluate the performance of the aerosol chamber
Q3 Complete testing effect on particle size, aerosol concentration, and wind speed for the passive sampler
Q4 Complete testing effect on particle size, aerosol concentration, and wind speed for the passive sampler
Manuscripts published or submitted to peer review journals (approx. 1)

This project has resulted in two employee invention reports
This project has contributed to the PPE section in Chapter 4 of the NIOSH Nanotechnology Research Center (NTRC) document titled "Progress toward Safe Nanotechnology in the Workplace" and the NTRC report titled "Approaches to Safe Nanotechnology: An Information Exchange with NIOSH" Feb. 2007.
This project has resulted in a new research proposal entitled "Nanoparticle penetration through protective clothing", which has been selected and funded by NIOSH NTRC for a new FY09 project. Feb. 2007.
Expected end outcome is reduced occupational dermal exposure to aerosol, bioaerosols, and nanoparticles through improved standards and test methods for protective clothing
