Implementation Of National Policies For A Total Asbestos Ban: A Global Comparison, Ro-Ting Lin Phd, Lung-Chang Chien Drph, Masamine Jimba Phd, Sugio Furuya Bec, Ken Takahashi Phd

Environmental & Global Health Faculty Research

Background Two international Conventions from the International Labor Organization (ILO; C162 Asbestos Convention) and the UN (Basel Convention) offer governments guidelines for achieving a total asbestos ban policy, but the long-term effect of these Conventions on policy implementation, and the role of government effectiveness, remains unknown. We aimed to investigate associations between government ratification of the ILO and UN international Conventions, government effectiveness, and implementation of a national total asbestos ban. Methods We obtained data for year of a national asbestos ban, year of ratification of one or both international Conventions, and World Bank government effectiveness scores for 108 countries …

Modeling Irrigation Behavior In Groundwater Systems, Timothy Foster, Nicholas Brozovic, Adrian P. Butler

Daugherty Water for Food Global Institute: Faculty Publications

Integrated hydro-economic models have been widely applied to water management problems in regions of intensive groundwater-fed irrigation. However, policy interpretations may be limited as most existing models do not explicitly consider two important aspects of observed irrigation decision making, namely the limits on instantaneous irrigation rates imposed by well yield and the intraseasonal structure of irrigation planning. We develop a new modeling approach for determining irrigation demand that is based on observed farmer behavior and captures the impacts on production and water use of both well yield and climate. Through a case study of irrigated corn production in the Texas …

Water Productivity In Meat And Milk Production In The Us From 1960 To 2016, Mesfin Mekonnen, C.M.U. Neale, Chittaranjan Ray, Galen E. Erickson, Arjen Y. Hoekstra

Daugherty Water for Food Global Institute: Faculty Publications

Global demand for livestock products is rising, resulting in a growing demand for feed and potentially burdening freshwater resources to produce this feed. To offset this increased pressure on water resources, the environmental performance of livestock sector should continue to improve. Over the last few decades, product output per animal and feedstuff yields in the US have improved, but before now it was unclear to what extent these improvements influenced the water productivity (WP) of the livestock products. In this research, we estimate changes in WP of animal products from 1960 to 2016. We consider feed conversion ratios (dry matter …

Federal Jurisdiction For Above-Ground Oil Storage Tanks: A Practical Analysis For Navigating Federal Regulations, Kathryn Hussong

St. Mary's Law Journal

Clear, consistent, and concise jurisdictional boundaries will aid pipeline operators to determine which regulations apply to their operations and associated facilities. This will help alleviate legal and financial risk to pipeline operators, who may be liable for noncompliance regardless of whether the pipeline operator or the associated refinery commits the violation. Overlapping state and federal regulations of pipelines and refineries has created confusion amongst operators regarding what regulations apply to their facilities. Three federal agencies—the Pipeline and Hazardous Safety Administration (PHMSA), the Occupational Safety and Health Administration, and the Environmental Protection Agency (EPA) respectively—and a myriad of state agencies simultaneously …

How Pennsylvanians Define Environmental Justice, Kayla Hofmann

Sociology Summer Fellows

The Pennsylvania Department of Environmental Protection (DEP) defines an environmental justice area as any census tract that partially or wholly includes a 30 percent or greater minority population or 20 percent or more of a population living in poverty. However, little is known about how the average Pennsylvanian defines environmental justice, hindering our ability to determine whether the current definition is adequate. Using transcripts from nine listening sessions on the DEP’s tour of affected counties, I address 3 questions: (1) How do people define environmental justice? (2) What do people think are the most pressing issues in each county? And …

Plastics By The Number, Andrew N. Rowan

WellBeing News

Great Britain’s Royal Statistical Society selected a “plastic fact” – that 90.5% of all plastics ever made have never been recycled – as its Statistic of the Year. Plastic waste is now so widespread that it has been proposed as an indicator of the beginning of the Anthropocene era when humans began to alter the world’s ecosystem significantly. The amount of plastic that has entered the oceans is actually a relatively small percentage of the total and, with concerted global action, it should be possible to make a real difference and save the marine creatures that are dying because their …

Mathematics, Physics, and Computer Science Faculty Articles and Research

Live fuel moisture (LFM) is a field-measured indicator of vegetation water content and a crucial observation of vegetation flammability. This study presents a new multi-variant regression model to estimate LFM in the Mediterranean ecosystem of Southern California, USA, using the Soil Moisture Active Passive (SMAP) L-band radiometer soil moisture (SMAP SM) from April 2015 to December 2018 over 12 chamise (Adenostoma fasciculatum) LFM sites. The two-month lag between SMAP SM and LFM was utilized either as steps to synchronize the SMAP SM to the LFM series or as the leading time window to calculate the accumulative SMAP SM. …

Assessment Of Excess Thyroid Cancer Risk Following A Hypothetical Radiological Incident In Louisiana And Best-Case Risk Reduction Achieved By Thyroid Blockade, Garrett A. Otis

LSU Master's Theses

Radioactive isotopes of iodine are produced by nuclear power plants as a byproduct of nuclear fission reactions. If these isotopes are released into the environment, such as during a breach of containment, they constitute a health risk to exposed individuals. To mitigate the risk of thyroid cancer due to exposure to radioactive iodine, “iodide prophylaxis,” also known as “thyroid blockade,” can be used, usually by administration of potassium iodide (KI). In some areas of the world, KI has been provided to the general public by their governments as a precautionary measure against potential nuclear power plant incidents. However, in the …

A Tourism Impact Index For Water-Based Natural Attractions Field-Tested In Subarctic And Maritime Climates, Jason Fox

Masters Theses & Specialist Projects

Tourism in cold and cool-climate regions is largely characterized by recreational and sightseeing activities at water-based natural attractions such as beaches, coastal cliffs, and waterfalls. While the economic benefits of the tourism industry can contribute to a sustainable future for these regions, the environmental implications of a hastilydeveloped industry cannot be ignored given that cold-climate and cool-climate landscapes are at risk of rapid environmental change from a warming climate and other environmental concerns. This study consisted of the development of the Tourism Impact Index for Water-Based Natural Sites, the first of its kind, and its application and refinement in the …

An Urban Karst Aquifer Resource Evaluation And Monitoring Toolbox, Rachel Anne Kaiser

Masters Theses & Specialist Projects

In urban karst areas, such as the City of Bowling Green, Kentucky and the Tampa Bay Metropolitan Area, groundwater quality faces a variety of threats. The development of residential, commercial, and industrial landuse types allows for a wide variety of groundwater pollutants to enter the karst groundwater systems. Various different models and indices have attempted evaluative approaches to identify issues in urban karst areas, but the methods vary by location and lack a focus on urban karst groundwater quality. There also exists a lack of a data-driven approach that is able to capture short- and long-term changes in threats to …

Data From: Microplastic Concentrations In Two Oregon Bivalve Species: Spatial, Temporal, And Species Variability, Britta Baechler, Elise F. Granek, Matthew V. Hunter, Kathleen E. Conn

Environmental Science and Management Datasets

Microplastics are an ecological stressor with implications for ecosystem and human health when present in seafood. We quantified microplastic types, concentrations, anatomical burdens, geographic distribution, and temporal differences in Pacific oysters (Crassostrea gigas) and Pacific razor clams (Siliqua patula) from 15 Oregon coast, U.S.A. sites. Organisms were chemically digested and visually analyzed for microplastics, and material type was determined using Fourier Transform Infrared Spectroscopy. Microplastics were present in organisms from all sites. On average, whole oysters and razor clams contained 10.95 ± 0.77 and 8.84 ± 0.45 microplastic pieces per individual, or 0.35 ± 0.04 and …

Environmental Studies Faculty Publications

More than half of the world's 18 penguin species are declining. We, the Steering Committee of the International Union for Conservation of Nature Species Survival Commission Penguin Specialist Group, determined that the penguin species in most critical need of conservation action are African penguin (Spheniscus demersus) , Galápagos penguin (Spheniscus mendiculus) , and Yellow‐eyed penguin (Megadyptes antipodes) . Due to small or rapidly declining populations, these species require immediate scientific collaboration and policy intervention. We also used a pairwise‐ranking approach to prioritize research and conservation needs for all penguins. Among the 12 cross‐taxa research areas we identified, we ranked quantifying …

Incorporating Antecedent Soil Moisture Into Streamflow Forecasting, Abdoul Oubeidillah, Glenn Tootle, Thomas Piechota

Mathematics, Physics, and Computer Science Faculty Articles and Research

This study incorporates antecedent (preceding) soil moisture into forecasting streamflow volumes within the North Platte River Basin, Colorado/Wyoming (USA). The incorporation of antecedent soil moisture accounts for infiltration and can improve streamflow predictions. Current Natural Resource Conservation Service (NRCS) forecasting methods are replicated, and a comparison is drawn between current NRCS forecasts and proposed forecasting methods using antecedent soil moisture. Current predictors used by the NRCS in regression-based streamflow forecasting include precipitation, streamflow persistence (previous season streamflow volume) and snow water equivalent (SWE) from SNOTEL (snow telemetry) sites. Proposed methods utilize antecedent soil moisture as a predictor variable in addition …

Species Determination Of Ulvoid Algae Through Genotyping; What Are The Environmental Implications?, Kora S. Krumm

Honors Projects

Ulva is a genus of marine green algae native to many of the world’s coastlines and is especially difficult to identify via traditional methods such as dichotomous keying. This project aims to streamline taxonomic classification of Ulva species through DNA sequence analysis. Local samples of Ulva were obtained from Puget Sound, Seattle, WA, and two target genes (rbcL and its1) were amplified via PCR and sequenced for comparative analysis between samples. Ulvoids have a detrimental impact on marine ecosystems in the Pacific Northwest due to their role in eutrophication-caused algal blooms, and reliable identification can help inform conservation …

Assessment Of Agricultural Drought Considering The Hydrological Cycle And Crop Phenology In The Korean Peninsula, Chul-Hee Lim, Seung Hee Kim, Jong Ahn Chun, Menas Kafatos, Woo-Kyun Lee

Mathematics, Physics, and Computer Science Faculty Articles and Research

Hydrological changes attributable to global warming increase the severity and frequency of droughts, which in turn affect agriculture. Hence, we proposed the Standardized Agricultural Drought Index (SADI), which is a new drought index specialized for agriculture and crops, and evaluated current and expected droughts in the Korean Peninsula. The SADI applies crop phenology to the hydrological cycle, which is a basic element that assesses drought. The SADI of rice and maize was calculated using representative hydrological variables (precipitation, evapotranspiration, and runoff) of the crop growing season. In order to evaluate the effectiveness of SADI, the three-month Standardized Precipitation Index, which …

In recent decades, subsidence in southeast Louisiana has become a topic of substantial and growing concern to the scientific community, the local residents, and all those invested in the region. Lidar data were acquired from the United States Geological Survey (USGS) and the LSU Center for Geoinformatics. The data has been manipulated to map the differenced Lidar, complete an instantaneous slope analysis, and determine the thickness of the Holocene …

Wildfire Exposure To Critical Habitat Of Endangered And Threatened Species In California, Kristin Butcher

Master's Theses

Researchers, fire ecologists and wildlife managers are concerned about impact to endangered and threatened species and their critical habitat due to the projected increase in future wildfires. Wildfires have been studied in California for the last six decades and have been increasing at an alarming rate since the 1980’s. In this study, I use the 2018 spatial dataset for critical habitat of federally endangered and threatened species located in the state boundaries of California and compare it to a spatial dataset for wildfires that have occurred over the span of 32 years (1984 to 2016). Trends are derived from spatial …

Riparian Resilience In The Face Of Interacting Disturbances, Alexa S. Whipple

2019 Symposium

Riparian systems of the dryland western United States provide critical ecosystem functions such as diverse habitat for numerous species, flood attenuation and essential water storage in water-limited environments. These systems have experienced long term disturbance from anthropogenic activities including the grazing of livestock in dryland riparian systems and near extirpation of a keystone riparian species, Castor canadensis (beaver). However, increasing frequency of large-scale wildfires and climate change driven weather is altering the severity and scale of riparian disturbance. Beaver restoration has been gaining use to address long term riparian disturbances, yet little is understood regarding the impact of restored beaver …

Nature As Privilege: How Environmental Racism Changes The Access To Fresh Air And The Effects On New York City’S Communities, Sarah C. Morrison

Student Theses 2015-Present

This paper serves to addresses the issue of environmental racism in relation to New York City, and more specifically comparing the South Bronx and Central Brooklyn, often characterized as low- income and high-minority populations with their white counterparts. New York, among other urban centers in the United States serves as an example of environmental racism because of the discrepancy in high air pollution levels in marginalized communities, the subsequent negative health effects (specifically asthma), and the lack of green spaces. The root of this issue is prominent in the history and construction of New York during the 1900s. The construction …
