Sublethal Toxicity Of Microcystis And Microcystin-Lr In Fish, 2010 University of Tennessee - Knoxville
Sublethal Toxicity Of Microcystis And Microcystin-Lr In Fish, Emily Dawn Rogers
Doctoral Dissertations
The occurrence of blooms of toxic cyanobacteria in freshwater environments is a global ecological and public health concern. Species of Microcystis are of particular importance because blooms occur in many freshwater environments throughout the world and microcystin toxin concentrations can exceed World Health Organization advisory levels. While microcystin has been associated with fish kills, sublethal effects of chronic exposure at environmentally relevant concentrations are relatively unknown. The objective of this research was to evaluate toxicity of microcystin and Microcystis in fish during all life history stages. We evaluated global gene expression response in larval zebrafish (Danio rerio), and …

Pharmacokinetic Evaluation Of The Blood: Tissue Relationship In Poultry: Screening For Antibiotic Residues In Chicken Muscle, Ixchel Reyes Herrera
Graduate Theses and Dissertations
During their life, humans are exposed to numerous substances that are naturally present in the environment or that are the result of man made processes, including heavy metals, persistent organic pollutants, pesticides and veterinary drugs. Some of these substances can leave residues in food products and possibly expose consumers to their potential toxic effects. To address these problems extensive regulatory efforts are devoted to prevent, detect and control these substances from reaching the food supply. However, given the vast diversity of food products that requires monitoring and the immense diversity of potential chemical contaminants, the need for an efficient and …

Trace Metal Concentrations Across Trophic Levels In Cotton Fields Of Xinjiang Province, China, Jessica Quinn
All Student Theses
Trace metals become concentrated in urban and peri-urban soils with the use of agricultural practices and industrial emissions. Fertilizers, liming, sewage sludge, and irrigation water contain metals which accumulate in agricultural fields and pose a risk to humans and wildlife. Coal plants and brickyards release metals into the atmosphere which are deposited on soil and plant surfaces. This research quantifies the concentrations of nine trace metals in three different soil types. A total of 116 rodents were sampled in cotton fields and a desert. Cotton plants and triplicate soil samples were collected with each rodent capture. Soil samples were analyzed …

Pesticide Use And Awareness On Pemba Island, 2010 SIT Study Abroad
Pesticide Use And Awareness On Pemba Island, Brooke Shorett, Lauren Crask
Independent Study Project (ISP) Collection
Use and awareness of pesticides by 301 farmers on Pemba Island, Tanzania, were surveyed, in order to assess practices and perceptions of pesticide use. Surveys were conducted in both peri-urban farms and rural farms, which were either irrigated or rain-fed. Results showed that while the overwhelming majority of farmers on irrigated fields used pesticides frequently, farmers located in rain-fed irrigation largely farmed without pesticides. Likewise, peri-urban farmers made use of pesticides far more than rural farmers. Of the farmers who did use pesticides, an average of Tsh 17,219 was spent annually on Rogol, Satunil, Dimethoate, Simithion, Thionex and Dursban. Most …

Background: Promotion of the HIV epidemic by aflatoxin is postulated but not yet established. Sub-Saharan populations commonly consume food contaminated by mycotoxins, particularly aflatoxins (predominantly found in peanut, maize, rice, and cassava) and fumonisins, which occur primarily in maize. Aflatoxin promotes hepatocellular cancer, and fumonisin may promote esophageal cancer.
Objectives: This analysis was undertaken to test the hypotheses that consumption of mycotoxin-prone staple foods is 1) related to the incidence of HIV infection in Africa and 2) related to “signature” cancer rates confirming exposure to aflatoxins and fumonisins.
Design: World Health Organization data for causes of death and the Food …

Quantifying Legacy Effects Of Managed Disturbance On Sagebrush Steppe Resilience And Diversity, 2010 Utah State University
Quantifying Legacy Effects Of Managed Disturbance On Sagebrush Steppe Resilience And Diversity, Julie Ripplinger
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Land-use legacies can affect landscapes for decades to millennia. A long history of shrub management exists in the sagebrush steppe of the Intermountain West where shrub-removal treatments, a type of managed disturbance, have been implemented for over 50 years to reduce sagebrush cover. The assumption behind managed disturbances is that they will increase forage for domestic livestock and improve wildlife habitat. However, the long-term effects of managed disturbance on plant community composition and diversity are not well understood. We investigated the legacy effects of three common types of managed disturbance (chemical, fire, and mechanical treatments) on plant community diversity and …

A Gis Analysis Of The Environmental Variables Related To Rift Valley Fever Outbreaks, Jacqueline Florette Jackson
Health Services Research Dissertations
Rift Valley fever is a mosquito-borne disease that causes widespread febrile illness and mortality in domestic animals as well as humans (Gaff, 2007). Rift Valley fever virus was first isolated in 1931 (Daubney, 1931), and since then, outbreaks have occurred in sub-Saharan Africa, southern Africa, Egypt, Saudi Arabia, Yemen and Madagascar, proving it to be a virus able to invade ecologically diverse regions (Gaff, 2007). The potential introduction of Rift Valley fever into the United States suggests the potential for human infection and major economic disruption. It is important to understand the role environmental variables have played in historical outbreaks …
