Quantifying The Variability In Heavy Metal Concentrations In Produce Grown In Metals-Rich Soil, Harris Lowell Byers
Quantifying The Variability In Heavy Metal Concentrations In Produce Grown In Metals-Rich Soil, Harris Lowell Byers
Theses and Dissertations
Childhood Pb exposure is associated with a multitude of poor health outcomes. In food-insecure areas, growing fresh produce in residential backyard gardens is one option for parents; however, commonly grown crops are known to accumulate Pb in consumable tissues when grown in metals-rich soils. A variety of produce representing a continuum of consumable tissues were grown in soils collected from two residential vegetable gardens, a former metal foundry, and commercial topsoil purchased from a local hardware store. The concentrations of heavy metals in crop tissues were measured with custom wavelength dispersive X-ray Fluorescence (WD-XRF) spectroscopy and portable energy dispersive X-ray …
Cyanobacterial Harmful Algal Bloom Ecology And Cyanotoxins In The Eutrophic Lake Winnebago-Green Bay Water System, Sarah L. Bartlett
Cyanobacterial Harmful Algal Bloom Ecology And Cyanotoxins In The Eutrophic Lake Winnebago-Green Bay Water System, Sarah L. Bartlett
Theses and Dissertations
Cyanobacterial harmful algal blooms (cyanoHABs) are frequently observed in water bodies used for recreation and drinking water production and can be detrimental to humans, animals, and general water quality. CyanoHABs are natural occurrences, but human activities such as agriculture, land use change, and runoff from urban and rural landscapes can promote and accelerate their expansion. The blooms are aesthetically unpleasing scums and can be laden with toxins (cyanotoxins) and toxic or otherwise bioactive peptides (TBPs) that can be harmful to humans and animals. Despite the vast research on cyanoHABs, cyanotoxin and TBP diversity and dynamics within a water column are …

Functional Characterization Of Lt-Hsc Metabolic Activity Dependent On Ahr Activity, Everett Tate
Theses and Dissertations
The cells of the immune system are descended from multipotent hematopoietic stem cells (HSCs) that emerge during development. Multipotency means that a single progenitor HSC can differentiate into any cell of the immune system. HSCs are required to do this for the lifetime of the organism through a process called self-renewal, and as such, any perturbation during development or in the bone marrow can have a trickle-down effect, affecting the self-renewal capacity or ability to terminally differentiate. The aryl hydrocarbon receptor (AHR) is a known regulator of HSCs. The AHR is a transcription factor required for the detoxification of numerous …
