The Connection Between Indoor Air Quality And Mental Health Outcomes, William L. Taylor Mar 2020

The Connection Between Indoor Air Quality And Mental Health Outcomes, William L. Taylor

Theses and Dissertations

Mental health among United States citizens, military members, and veterans warrant research into factors not fully considered for their effects on mental health. The built environment is increasingly recognized as a potential influence on the mental health of occupants. Specifically, indoor air quality is theorized to contribute to mental illness. Through the development of a literature review, specific air pollutants common in the built environment were identified, and the mechanisms behind their effect on mental health were explored. A model framework is outlined, estimating the number of cases of major depressive disorder attributable to indoor exposure to particulate matter. The …

Chromate Dissociation From Primer Paint In Simulated Lung Fluid, Tiffany J. R. Morgan Mar 2000

Chromate Dissociation From Primer Paint In Simulated Lung Fluid, Tiffany J. R. Morgan

Theses and Dissertations

OSHA has proposed a new strontium chromate exposure standard that would potentially cause Air Force paint facilities to be in violation of the proposed standard if adopted. This proposed reduction make the continued use of chromate containing primer paints very difficult. There is currently no acceptable replacements for chromate containing primer paints on AF aircraft. This study suggests that paint particles with chromate bound in primer paint may be unavailable for bodily absorption if inhaled and a reduced standard for painting applications may be unnecessary. Primer paint overspray was collected into simulated lung fluid (SLF) and allowed 6 hr, 24 …

Heavy Metal Toxicity In Bioremediation: Microbial Cultures And Microscopy, Jason B. Goodbody Dec 1997

Heavy Metal Toxicity In Bioremediation: Microbial Cultures And Microscopy, Jason B. Goodbody

Theses and Dissertations

This research employed a variety of microscopy and spread plating techniques to observe the effects of heavy metal treatments on a toluene-selected bacterial population. Microbial colonies were cultured on spread plates and the resulting numbers were compared to respiration data. The mechanisms of reproduction were demonstrated to be more sensitive to metal treatments than were the mechanisms of respiration. Phase contrast, Gram stain, fluorescent microscopy, were used to compare and document a wide variety of bacteria resulting from different metal treatments as well as from environmental changes within the source bioreactor. The removal of sensitive bacteria and the selection of …

An Analysis Of 1994 Air Force Toxic Release Inventory Reporting, Brian A. Pollock Dec 1995

An Analysis Of 1994 Air Force Toxic Release Inventory Reporting, Brian A. Pollock

Theses and Dissertations

The purpose of this research is to analyze the Air Force's 1994 Toxic Release Inventory data. Statistical tests were used to meet the following research objectives: (1) review the CY 94 data to determine which chemicals were most often reported and which bases and major commands had the most releases in terms of the number of chemicals reported and the amount of chemicals reported and (2) investigate factors which could influence the reporting status of a facility. An analysis of the TRI data showed that dichloromethane was the chemical released in the largest amount while methyl ethyl ketone was the …

Modified Model For Transient Response Of Mrna Synthesis To Magnetic Field Exposure, Timothy W. Crosnoe Dec 1995

Modified Model For Transient Response Of Mrna Synthesis To Magnetic Field Exposure, Timothy W. Crosnoe

Theses and Dissertations

It is a well-known fact that high frequency, or radio frequency, radiation can be directly harmful to biological tissue. The radiation frequencies to which humans are most exposed, however, are the extremely low frequencies, or ELFs. To date there has been no definitive measure for predicting the ability of low frequency electromagnetic radiation to cause adverse biological effects. Two specific measures, average magnetic field and kinetic index, have been used in studies to determine if they are useful predictors of adverse effects, specifically leukemia. Unfortunately, both have shown only marginal results. This thesis analyzed and improved the kinetic index measure …

Development Of A Comprehensive Base-Level Environmental Training Program For Total Environmental Compliance, William M. Barrett Jr Sep 1994

Development Of A Comprehensive Base-Level Environmental Training Program For Total Environmental Compliance, William M. Barrett Jr

Theses and Dissertations

The leadership of the Air Force has established a goal of total environmental compliance because it is the right and necessary thing to do. Commitment to this goal can be accomplished through strong leadership, however, achieving this goal can only be accomplished through effective training. The lack of consistent guidance for developing and executing comprehensive base- level environmental training programs has forced bases to develop these training programs by whatever means available to them. This has resulted in a broad variation in the thoroughness of base-level training programs throughout the Air Force. This research effort investigates the relationship between the …

Development Of Field Guidance For Assessing Feasibility Of Intrinsic Bioremediation To Restore Petroleum-Contaminated Soils, John T. Enyeart Sep 1994

Development Of Field Guidance For Assessing Feasibility Of Intrinsic Bioremediation To Restore Petroleum-Contaminated Soils, John T. Enyeart

Theses and Dissertations

This research evaluated the process of intrinsic bioremediation, also called natural attenuation, and the parameters that affected it. The goal of this study was to use these intrinsic bioremediation parameters to develop a valid prediction of the cleanup duration using this restoration technology. This analysis was limited to a JP-4 release and focused on the remediation of the BTEX constituents to a cleanup level of 10 ppm total BTEX. The review of intrinsic bioremediation found that the BTEX hydrocarbons can aerobically and anaerobically biodegrade. Of the many factors that affect intrinsic bioremediation, those that most influenced its occurrence were the …
