Variability Of Air Sampling Results Using Air-O-Cell Cassettes, Christina M. Haworth
USF Tampa Graduate Theses and Dissertations
No current federal or state standards for mold exposure exist, partly due to the lack of accurate methods for assessing fungal exposure. Exposure to airborne fungal spores can result in several symptoms such as allergic rhinitis, coughing, and fatigue. Non-industrial occupational settings are common and fungal exposures may occur in these environments. The purpose of this study is to evaluate the meaningfulness of fungal spore trap results from samples collected in both a corporate office and a university classroom. Air-O-Cell cassettes with a Zefon Bio-Pump were used to collect one outdoor and three indoor samples at each location on three …

Particles In Welding Fumes, Rebecca T. Williams
USF Tampa Graduate Theses and Dissertations
The purpose of this study was to investigate whether or not differing base metals and filler wires used during welding processes contributed to differing amounts of ultrafine particles (UFP) and nanoparticles being emitted during the welding procedure. The study was also conducted to determine UFP and nanoparticle exposure in the breathing zones of the welders as well as the breathing zones of pipefitters and fire watchers, who commonly sit 6ft behind the welding arc. In order to determine if UFP and NP exposures differed with base metal and filler wire, all welding processes utilized the same welding machine for metal …

Asbestos Exposure In The Research Laboratory, Ediberto D. Garcia
USF Tampa Graduate Theses and Dissertations
Introduction: Asbestos has been employed in a myriad of industrial applications for more than a century. Of the 181 Mt of asbestos produced worldwide, over 31 Mt was consumed in the U.S. The production and consumption of this mineral eventually was found to cause asbestosis, lung cancer and mesothelioma. While the brunt of the human exposure to asbestos occurred in insulation work, many more workers in other jobs were expose to asbestos fibers. Very little is known about the potential exposure to asbestos in research labs.
Goal: In order to investigate potential research lab work exposures, we simulated lab work …
