Evaluation of personal aerosol samplers.
Aizenberg, Vitaly Alex.

Evaluation of personal aerosol samplers. - 287 p.

Chair: Sergey A. Grinshpun.

Thesis (Ph.D.)--University of Cincinnati, 2000.

The first goal of this dissertation was the development, evaluation and validation of the Simplified Protocol for testing of personal inhalable aerosol samplers. Traditionally, personal inhalable aerosol samplers are evaluated in large wind tunnels. This is very time consuming and involves significant operational expenses. A Simplified Test Protocol is described and evaluated here. It was tested in a large conventional and a specially-designed small wind tunnels. The sampling efficiencies of four personal aerosol samplers measured at a variety of sampling conditions according to the conventional approach and the Simplified Protocol in the large and small wind tunnels demonstrated no statistically significant difference. Thus, the Simplified Test Protocol was shown to be suitable for the performance evaluation of personal inhalable aerosol samplers. The Simplified Test Protocol was utilized to measure the sampling efficiencies of the IOM, GSP, and Button Samplers challenged with large (up to 250 mum) particles in the small wind tunnel. The sampling efficiency of the IOM increased with the particle aerodynamic diameter, while that of the GSP and the Button Sampler did not change.

520 $a The first goal of this dissertation was the development, evaluation and validation of the Simplified Protocol for testing of personal inhalable aerosol samplers. Traditionally, personal inhalable aerosol samplers are evaluated in large wind tunnels. This is very time consuming and involves significant operational expenses. A Simplified Test Protocol is described and evaluated here. It was tested in a large conventional and a specially-designed small wind tunnels. The sampling efficiencies of four personal aerosol samplers measured at a variety of sampling conditions according to the conventional approach and the Simplified Protocol in the large and small wind tunnels demonstrated no statistically significant difference. Thus, the Simplified Test Protocol was shown to be suitable for the performance evaluation of personal inhalable aerosol samplers. The Simplified Test Protocol was utilized to measure the sampling efficiencies of the IOM, GSP, and Button Samplers challenged with large (up to 250 mum) particles in the small wind tunnel. The sampling efficiency of the IOM increased with the particle aerodynamic diameter, while that of the GSP and the Button Sampler did not change.
520 $a The second goal of this dissertation was the laboratory and field evaluation of the Button Sampler as compared to other commercially available aerosol samplers. First, the airflow patterns near the sampler's inlet were studied using the Laser-Doppler Velocimetry. They were found to be similar regardless of the wind velocity and the presence of a stagnation plate simulating a human torso for the sampler facing the wind. The effect of the wind velocity on the Button Sampler's sampling efficiency was found to be statistically significant, while the wind and direction non-significant factor.
520 $a The heavy metal exposure of workers performing abrasive blasting operations was evaluated based on the personal sampling data obtained with the Button Samplers. The respiratory protection used was found to adequately protect against lead exposure. However, the workers were not adequately protected against cadmium and chromium.
520 $a A novel application of the Button Sampler, the total enumeration of airborne microorganisms, was investigated. The Button Sampler demonstrated the highest physical collection efficiency, total microbial counts and particle surface density when compared to two commercially available impactor devices. Thus, the Button Sampler is suitable for the enumeration of total airborne spores.
