Sources And Toxicity Of Mercury In The San Francisco Bay Area, Spanning California And Beyond., Mietek Kolipinski, Mani Subramanian, Kristina Kristen, Steven Borish, Stacy Ditta

Natural Sciences and Mathematics | Faculty Scholarship

This report synthesizes and evaluates published scientific literature on the environmental occurrence and biomagnification of mercury with emphasis on the San Francisco Bay Area (SFBA), California. Mercury forms various compounds, well known for their toxicity in humans and environmental ecosystems. Elemental mercury is transported and distributed by air, water, and sediments. Through the metabolic processes of algae and bacteria, mercury is converted into organic compounds, such as methylmercury (MeHg), which then bioaccumulates up through trophic levels. In fish, it is found primarily in skeletal muscle, while in humans, the primary target organs are the brain and kidneys. Health concerns exist ...


Remaking Environmental Justice, Clifford Villa 2020 University of New Mexico - School of Law

Remaking Environmental Justice, Clifford Villa

Faculty Scholarship

From movements for civil rights in the 1960s and environmental protection in the 1970s, the environmental justice movement emerged in the 1980s and 1990s to highlight the disparate impacts of pollution, principally upon people of color and low-income communities. Over time, the scope of environmental justice expanded to address concerns for other dimensions of diversity. New and continuing challenges tell us that we need to reframe our understanding of environmental justice to ensure better protection for people going forward. One way to reframe this understanding may be to apply the heuristic of vulnerability analysis as proposed by legal theorist Martha ...

Daugherty Water for Food Global Institute: Faculty Publications

Crop biomass (Bio) is one of the most important parameters of a crop, and knowledge of it before harvest is essential to help farmers in their decision making. Both green and dry Bio can be estimated from vegetation spectral indices (VIs) because they have a close relationship with accumulated absorbed photosynthetically active radiation (APAR), which is proportional to total Bio. The aims of this study were to analyze the potential capacity of spectral vegetation indices in estimating corn green biomass based on their relationship with the photosynthetic vegetation sub-pixel fraction derived from spectral mixture analysis and to analyze the best ...

An Exploration Of Zero Waste Policies And Recommendations For Missoula, Sarah Blyth Lundquist

Graduate Student Theses, Dissertations, & Professional Papers

“Zero Waste” is a concept and community goal that has arisen to challenge the current consumerist economic system and offer solutions for a number of environmental issues. In adopting this goal, individuals and communities pledge to reduce and divert at least 90% of their waste in a certain number of years. These goals can be reached by employing policies, programs, and other intervention tactics which establish Zero Waste infrastructure, ensure equitable and widespread access to Zero Waste services, and provide educational outreach and resources to the community. Missoula adopted a Zero Waste goal in 2016 and created a Zero Waste ...

Distribution Of Human Exposure To Ozone During Commuting Hours In Connecticut Using The Cellular Device Network, Owais Gilani, Simon Urbanek, Michael J. Kane

Faculty Journal Articles

Epidemiologic studies have established associations between various air pollutants and adverse health outcomes for adults and children. Due to high costs of monitoring air pollutant concentrations for subjects enrolled in a study, statisticians predict exposure concentrations from spatial models that are developed using concentrations monitored at a few sites. In the absence of detailed information on when and where subjects move during the study window, researchers typically assume that the subjects spend their entire day at home, school, or work. This assumption can potentially lead to large exposure assignment bias. In this study, we aim to determine the distribution of ...

Reconstructing Hydrologic Conditions And Metals Supplied By The Peace River To The Peace-Athabasca Delta, Jelle André Faber

Theses and Dissertations (Comprehensive)

The Peace-Athabasca Delta (PAD) in northern Alberta, Canada, is recognized internationally for its ecological, historical, and cultural significance. The delta is mostly within Wood Buffalo National Park, a UNESCO World Heritage Site, and is a Ramsar Wetland of International Importance. The construction of the WAC Bennett Dam (1967) and the Site C Dam (ongoing, 2024) on the Peace River, and expansion of the Alberta Oil Sands industry along the Athabasca River have raised concerns over water quantity and quality in the delta. When industry operations began, effective monitoring had not been implemented. Consequently, pre-industrial reference conditions are unknown and can ...

Microcystins And Liver Disease Mortality, Insights From An Ecological Study, Rajesh Tirpaul Melaram

Walden Dissertations and Doctoral Studies

Microcystins (MCs) are toxic secondary metabolites produced by freshwater cyanobacteria. Algal bloom subsidence can stimulate MC release, which can impair liver function if orally exposed to in large doses. The purpose of this retrospective, U.S. ecological study was to determine if MC exposure represented an environmental risk factor for liver disease mortality using a socioecological approach. A longitudinal ecological substudy investigated the association between average total MCs in Lake Washington and Lake Manatee and age-adjusted chronic liver disease (CLD)/cirrhosis death rates in Brevard County and Manatee County, Florida (FL). A prediction model of total MCs was deduced by ...


The Impact Of Biochar Treatment On H2s And Nh3 Emissions During Manure Agitation Prior To Pump-Out, Baitong Chen, Jacek A. Koziel, Myeongseong Lee, Hantian Ma, Zhanibek Meiirkhanuly, Peiyang Li, Andrzej Białowiec, Robert C. Brown 2020 Iowa State University

The Impact Of Biochar Treatment On H2s And Nh3 Emissions During Manure Agitation Prior To Pump-Out, Baitong Chen, Jacek A. Koziel, Myeongseong Lee, Hantian Ma, Zhanibek Meiirkhanuly, Peiyang Li, Andrzej Białowiec, Robert C. Brown

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

Hydrogen sulfide and ammonia are always a concern in the livestock industries, especially when farmers try to clear their manure storage pits. Agitation of manure can cause dangerously high concentrations of harmful agents such as H2S and NH3 to be emitted into the air. Biochar can absorb these gases. We hypothesized that applying biochar on top of manure can create an effective barrier to protect farmers and animals from exposure to NH3 and H2S. In this study, one kind of biochar was tested, highly alkaline, and porous (HAP, pH 9.2) biochar made from ...

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

Gaseous emissions, a side effect of livestock and poultry production, need to be mitigated to improve sustainability. Emissions of odorous gases like ammonia (NH3) have a detrimental effect on the environment. We are building on previous research to bring advanced oxidation technologies from the lab to the farm. To date, we have shown that ultraviolet A (UV-A) has the potential to mitigate selected odorous gases in the swine production. Much less research on emissions mitigation has been conducted in the poultry production. Thus, the study objective was to investigate whether the UV-A can mitigate NH3 that is a surrogate gas ...


A Modeling Approach To Understanding Glyphosate Transport In The Belize River Watershed, Barbara Anmei Astmann 2020 University of Kentucky

A Modeling Approach To Understanding Glyphosate Transport In The Belize River Watershed, Barbara Anmei Astmann

Theses and Dissertations--Civil Engineering

Glyphosate is the most widely used herbicide worldwide and is often transported from application areas to surface water when solubilized in runoff or sorbed to eroded sediment. There is evidence that suggests both glyphosate and its main metabolite aminomethylphosphonic acid (AMPA) may pose a risk to human health, as well as cause adverse effects in the environment. However, consistent monitoring data is still limited, especially in developing countries. Belize is a developing nation with agriculture being a major sector of its economy and is heavily reliant on glyphosate. The widespread use of glyphosate in Belize may be resulting in glyphosate ...

Enhancing Models And Measurements Of Traffic-Related Air Pollutants For Health Studies Using Dispersion Modeling And Bayesian Data Fusion, Stuart A. Batterman, Veronica J. Berrocal, Chad Milando, Owais Gilani, Saravanan Arunachalam, K. Max Zhang

Faculty Journal Articles

Research Report 202 describes a study led by Dr. Stuart Batterman at the University of Michigan, Ann Arbor and colleagues. The investigators evaluated the ability to predict traffic-related air pollution using a variety of methods and models, including a line source air pollution dispersion model and sophisticated spatiotemporal Bayesian data fusion methods. Exposure assessment for traffic-related air pollution is challenging because the pollutants are a complex mixture and vary greatly over space and time. Because extensive direct monitoring is difficult and expensive, a number of modeling approaches have been developed, but each model has its own limitations and errors.

In this manuscript, we discuss relevant socioeconomic factors for developing and implementing sensor analytic point solutions (SNAPS) as point-of-care tools to serve impoverished communities. The distinct economic, environmental, cultural, and ethical paradigms that affect economically disadvantaged users add complexity to the process of technology development and deployment beyond the science and engineering issues. We begin by contextualizing the environmental burden of disease in select low-income regions around the world, including environmental hazards at work, home, and the broader community environment, where SNAPS may be helpful in the prevention and mitigation of human exposure to harmful biological vectors and chemical agents ...

U.S. Environmental Protection Agency Papers

The Prairie Pothole Region of North America is characterized by millions of depressional wetlands, which provide critical habitats for globally significant populations of migratory waterfowl and other wildlife species. Due to their relatively small size and shallow depth, these wetlands are highly sensitive to climate variability and anthropogenic changes, exhibiting inter- and intra-annual inundation dynamics. Moderate-resolution satellite imagery (e.g., Landsat, Sentinel) alone cannot be used to effectively delineate these small depressional wetlands. By integrating fine spatial resolution Light Detection and Ranging (LiDAR) data and multi-temporal (2009–2017) aerial images, we developed a fully automated approach to delineate wetland inundation ...
