In this study, the effectiveness of an electrostatic filter portable air purifier was evaluated (1) in a home where a wood stove was the sole heat source and (2) in a home where a wood stove was used as a supplemental heat source. Particle count concentrations in six particle sizes and particle mass concentrations in two particle sizes were measured for ten 12-hour purifier on and ten purifier off …

The Impact Of Tricaine Methanesulfonate, 2-Phenoxyethanol, And Carvone-Methyl Salicylate On The Innate Immune Response Of Zebrafish (Danio Rerio), Charles R. Wulff

Honors Theses

Anesthesia plays a vital role in the maintenance of aquaculture species, where it is used to minimize stress during complex handling tasks such as transport, assessment, and harvesting. However, anesthetics have been shown to suppress the innate immune response, which could impact immunity and increase risk of infection. Tricaine methanesulfonate (MS-222) and 2-Phenoxyethanol (2-PE) represent two of the most commonly used anesthetics in aquaculture, with R-(+)-carvone, in the form of carvone-methyl salicylate (CMS) has recently been proposed as an alternative anesthetic for food fish. These three anesthetics were used to assess the influence of anesthetics on the immune system of …

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 …

Invernaderos: La Búsqueda Por El Trabajo Estable Y Seguro Y Un Medioambiente En Peligro, Elli Matkin

Independent Study Project (ISP) Collection

This research is intended to discuss the rapid development of the “invernaderos” (greenhouses) on the coast of Spain and to expose both the social and environmental repercussions of such a massive agricultural project. The data was gathered through the use of both secondary sources and primary research. The author conducted a number of interviews both on the coast, in Motril and Carchuna, and inland in Granada city -- discussing the subject with owners of “invernaderos”, pesticide sellers, and cooperative workers.

The main conclusion of this research is that while the work of “invernaderos” is a security for many agricultural families …

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 …

Trace Metal Concentrations Across Trophic Levels In Cotton Fields Of Xinjiang Province, China, Jessica Quinn

All Student Theses and Dissertations

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 …

Hiv And Hepatocellular And Esophageal Carcinomas Related To Consumption Of Mycotoxin-Prone Foods In Sub-Saharan Africa, Jonathan H. Williams, Jessica A. Grubbs, Jerry W. Davis, Jia-Sheng Wang, Pauline E. Jolly, Nii-Ayi Ankrah, William O. Ellis, Evans Afriyie-Gyawu, Natalie M. Johnson, Abraham G. Robinson, Timothy D. Phillips

Environmental Health Sciences: Faculty Publications

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.

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 …
