Inequality Of Air Quality?: A Study Of Air Quality Within Housing Price Brackets In Gettysburg, Pa, Jess G. Schaefer, Alexis J. Jones, Arden H. Dowd
Inequality Of Air Quality?: A Study Of Air Quality Within Housing Price Brackets In Gettysburg, Pa, Jess G. Schaefer, Alexis J. Jones, Arden H. Dowd

With the rise of cars and other motorized vehicles has come the rise of air pollution, which tends to have disproportionate environmental and health impacts on low-income and communities of color. This study analyzes car presence and air quality on a transect within Gettysburg, PA to determine if there is a relationship between air pollution and vehicle presence, and if there is a difference in air quality between higher price bracket housing compared to campus, commercial, and lower price bracket housing. To test our research questions, we identified nine sampling locations along a transect where we measured air pollutants, including …

Air quality is critical for public health. Residents rely chiefly on government agencies such as the Environmental Protection Agency (EPA) in the United States to establish standards for the measurement of harmful contaminants including ozone, sulfur dioxide, carbon monoxide, volatile organic chemicals (VOCs), and fine particulate matter at or below 2.5 μm. According to the California Air Resources Board [1], “short-term PM2.5 exposure (up to 24-h duration) has been associated with premature mortality, increased hospital admissions for heart or lung causes, acute and chronic bronchitis, asthma attacks, emergency room visits, respiratory symptoms, and restricted activity days”. While public agency resources …
Environmental Factors And Human Health Interactions : Ultrafine Particles, Temperature Variability, And Proximity To Power Stations, Ian Ryan
Legacy Theses & Dissertations (2009 - 2024)
Background: Air pollution leads to more than four million premature deaths worldwide and nearly 200,000 in the US each year. While there is extensive research relating PM2.5 to hospital visits for various health outcomes, there is relatively little research on ultrafine particles (UFPs), a particularly small and dangerous air pollutant. Another important exposure is temperature due to its association with dehydration, heat stress, and cardiovascular-related hospital admissions. However, relatively little research has been conducted on diurnal temperature range (DTR), or the range of temperature within a single day, which is an important indicator of climate change. Importantly, the interaction between …

The Mobile Monitoring Of Particulate Matter Through Wearable Sensors And Their Influence On Students' Environmental Attitudes, Joseph M. Abbate
The Mobile Monitoring Of Particulate Matter Through Wearable Sensors And Their Influence On Students' Environmental Attitudes, Joseph M. Abbate
DePaul Discoveries
While we have a comprehensive understanding of air pollutants, and their spatiotemporal characteristics across global, and even regional, scales, we are quite limited in our capacity to monitor neighborhood-scale emissions. The mobile monitoring of air pollution is a growing field, prospectively filling in these gaps while personalizing air quality-based tools and risk assessment. In the present study, we developed wearable sensors for particulate matter (PM); and through a citizen science approach, students of partnering Chicago schools monitored PM concentrations throughout their commutes over a five-day period. While their recorded findings would be used to explore the relationship between PM concentrations …
The Effects Of Isoprene Emission From Native And Invasive Trees On Local Air Quality, Aarti P. Mistry
The Effects Of Isoprene Emission From Native And Invasive Trees On Local Air Quality, Aarti P. Mistry
DePaul Discoveries
Biogenic volatile organic compounds (BVOC) are the second-most abundant reactive gasses emitted into the atmosphere by the biosphere. Isoprene is a BVOC produced by the process of photosynthesis from vegetation and is emitted from plant leaves. Isoprene is a hydrocarbon that combines with oxides of nitrogen in the atmosphere to create ozone in the troposphere, an air pollutant. Invasive trees alter ecosystems and affect native tree populations. Invasive tree species in the Chicagoland area are outcompeting native tree species and expanding rapidly. The effect of isoprene emissions on air quality is a well-researched area in the atmospheric science community, however, …
Association Between Chemical Constituents Of Particulate Matter And Cardiovascular And Respiratory Morbidities In Nys, Rena Jones
Legacy Theses & Dissertations (2009 - 2024)
Improved understanding of health risks from short- and long-term exposure to fine particulate matter (PM2.5) constituents may explain seasonal and geographic heterogeneity in PM2.5-health associations and inform control efforts targeting PM sources. Few studies have examined PM species health effects; most have been limited by their exposure assessments and modeling approaches. The goals of this project were to improve the PM exposure assessment and explore relationships between PM2.5 species and health in acute and chronic contexts.

Introduction: Association between ambient air pollution and cardiovascular disease (CVD) have been demonstrated by many epidemiological studies in developed countries, however few studies have been performed in developing countries of Asia.
Indivisible Injury Negligence And Nuisance Cases –Proving Causation Among Multiple-Source Polluters: A State-By-State Survey Of The Law For New England, And A Proposal For A New Causation Framework, Paul Homer
The University of New Hampshire Law Review
[Excerpt] "The skies, soil, and water of every state are polluted every day. Whether the pollutants enter the atmos phere from coal plants or the water-ways from large farms, materials a bnormal to the “natural” environment are regularly emitted by a variety of sources over wide regions of the nation. To some extent, such emissions are normal and acceptable activities in modern society."
Validation Of Passive Air Sampling Monitors Onboard United States Navy Submarines, Larry A. Mcfarland
Validation Of Passive Air Sampling Monitors Onboard United States Navy Submarines, Larry A. Mcfarland
Community & Environmental Health Theses & Dissertations
An operating submarine creates a unique air quality mixture of compounds that result from a combination of human metabolism, construction materials, materials brought onboard and compounds created through the interaction of ship systems. A comprehensive study of submarine atmospheres is ongoing during deployments of U.S. Navy nuclear submarines. As part of the overall effort, a paired air sampling comparison field validation was conducted to compare the air sampling effectiveness of passive diffusive monitors compared to more traditional active air sampling methods when sampling for acrolein, formaldehyde and ozone in the enclosed submarine atmosphere. Acrolein monitors containing 2-hydroxymethylpiperidine (HMP) impregnated glass …
