Environmental health and public health are profoundly local. The Association of Environmental Health Academic Programs (AEHAP) firmly agrees and for this reason, it is important to have local environmental health experts who know the pulse of their communities. AEHAP believes in supporting the advanced scientific education of environmental health in these communities through people from these communities. Accordingly, AEHAP has sought to promote and support accredited environmental health programs among a diverse cross-section of the U.S. higher education landscape. AEHAP’s students are diverse in many ways, including socioeconomically, racially, ethnically, and culturally. The value of this approach enhances ...
Noise Exposure For Bus Drivers In An Iowa City Transit System, 2018 University of Iowa
Noise Exposure For Bus Drivers In An Iowa City Transit System, Austin Isamu Pierson
Theses and Dissertations
General noise regulations and guidelines protect workers against 8-hour time-weighted average noise exposures > 85-90 dBA that can cause health outcomes and noise induced hearing loss (NIHL), but the bus transportation industry has guidelines limiting lower noise exposures > 75-80 dBA to reduce safety hazards, including distraction and poor communication. These hazards can create dangerous driving conditions, especially for urban bus drivers, potentially causing a collision. Further research was necessary to characterize U.S. urban transit bus driver noise exposures to assess whether they exceeded 75, 80, 85, and 90 dBA, time-weighted, and to identify statistically significant noise exposure risk factors for ...

Particles In Welding Fumes, Rebecca T. Williams
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 ...
Ability Of The Iso Predicted Heat Strain Method To Predict A Limiting Heat Stress Exposure, 2018 University of South Florida
Ability Of The Iso Predicted Heat Strain Method To Predict A Limiting Heat Stress Exposure, Edgar Prieto
Graduate Theses and Dissertations
Heat stress is one of many physical agents to which thousands of workers are under constant exposure. Oftentimes it is necessary to work above the WBGT-based heat stress exposure limits. It is therefore important to consider alternative measures that include an exposure time limit to manage the heat stress. Predicted Heat Strain (PHS) (ISO7933) is one of those alternatives. PHS uses both personal factors like height and weight and job factors of environment, metabolic rate and clothing. The purpose of this project is to determine whether the PHS is an adequate method to predict short term exposure limits.

Long working hours are recognized as a risk factor for cerebrovascular and cardiovascular diseases (CCVD). We investigated the relationship between working hours and different CCVD severity outcomes—death, disability, and illness—across industries in Taiwan from 2006 to 2016. We applied a generalized additive mixed model to estimate the association between working hours and the rate of each severity outcome, adjusted for salary, unemployment rate, time, and a random intercept. Industry-average working hours were significantly associated with each outcome level of overwork-related CCVD, especially when monthly working hours increased from 169 (relative risk [RR] = 1.46, 95% confidence interval [CI ...

BACKGROUND: Glyphosate-based herbicides (GBHs) are the most widely used pesticides worldwide, and glyphosate is the active ingredient of such herbicides, including the formulation known as Roundup. The massive and increasing use of GBHs results in not only the global burden of occupational exposures, but also increased exposure to the general population. The current pilot study represents the first phase of a long-term investigation of GBHs that we are conducting over the next 5 years. In this paper, we present the study design, the first evaluation of in vivo parameters and the determination of glyphosate and its major metabolite aminomethylphosphonic acid ...

Assessing The Ordinality Of Response Bias With Item Response Models: A Case Study Using The Phq-9, Venessa N. Singhroy
All Dissertations, Theses, and Capstone Projects
Improper scale usage in psychological and clinical assessment is an important problem. If respondents do not use the scales in a consistent manner, the reliability of a composite is likely to be attenuated. This is particularly problematic when particular items are singled out for special treatment or when subscales are of interest, not just a total score. This study used both non-parametric and parametric item response theory (IRT) methods to gain further insight into the validity of the PHQ-9, a dual purpose instrument that assesses the severity of depressive symptoms using nine Likert-scale items and allows the investigator to establish ...
Development Of An Impinger Method For Sampling Airborne Nanocellulose, 2018 University of Iowa
Development Of An Impinger Method For Sampling Airborne Nanocellulose, Kevin Paul Gettz
Theses and Dissertations
An impinger-based sampling method was designed and evaluated for the collection of airborne cellulose nanocrystals (CNC). Plastic impingers were purchased and a custom nozzle was designed and 3D printed. Collection efficiency by particle size was compared to commercially available impingers. Collection efficiency (CE) was then adjusted theoretically for an impactor that would be used in a field setting to remove particles larger than 300 nm. Adjusted CE was compared to the nanoparticulate matter (NPM) criterion model, which mimics nanoparticle deposition in the human respiratory system. The impinger method was then used to collect rhodamine-tagged CNC to determine if it could ...
Barriers To The Adoption Of Safe Beef Cattle Handling Practices, Equipment, And Facilities In Iowa, 2018 University of Iowa
Barriers To The Adoption Of Safe Beef Cattle Handling Practices, Equipment, And Facilities In Iowa, Deann Scott-Harp
Theses and Dissertations
Agriculture is one of the most hazardous industries in the United States, with a fatality rate that consistently surpasses other industries. Livestock handling activities are often found to be the second or third leading cause of on-farm injuries, with machinery and falls being cited as other leading causes. Among all livestock, cattle are responsible for the most injuries and fatalities on farms, and cattle-related nonfatal injuries have been shown to be some of the most costly, and result in more time off work than other injuries. Despite the fact that research has improved our understanding of cattle behavior and sensory ...

Pesticide Drift In The Midwest: 2010-2016, Jessica L. Ricchio
Theses and Dissertations
Approximately 92% of the land in Iowa, 64% in Indiana, and 27% in Michigan is agricultural farmland. Nearly 77% of farmland in Iowa and Indiana, and 58% of farmland in Michigan, were treated with herbicides in 2012 (USDA). Pesticide drift, or “overspray”, is defined as any off-site movement of pesticide during its application. Exposure to this drift has the potential to damage crops and landscaping, kill aquatic animals, and cause DNA damage, cancer, and allergic wheeze in applicators. The Pesticide Bureau of the Iowa Department of Agricultural and Land Stewardship (IDALS), the Indiana State Chemist (ISC), and the Michigan Department ...
