Detection And Observed Correlations Of Statin And Beta-Blocking Pharmaceuticals In West Virginia Surface Waters And Ichthyofauna, Joseph W. Kingsbury
Detection And Observed Correlations Of Statin And Beta-Blocking Pharmaceuticals In West Virginia Surface Waters And Ichthyofauna, Joseph W. Kingsbury
Graduate Theses, Dissertations, and Problem Reports
Within this thesis the source, presence, and the estimated ecotoxicological effects of cardiovascular medicines, specifically statins and beta-blockers are described within the Buckhannon, Tygart Valley, and West Fork Rivers of West Virginia. Included within this thesis is a general introduction providing key background information and relevant research related to the source, presence, and known toxicity of statins and beta-blockers. Following the general introduction there are 3 distinct chapters. Chapter 1 focuses on the estimated demographic based source loadings and the surface water concentration characteristics of statins and beta-blockers within the three rivers. Chapter 2 investigates the effects of statins and …
Transcriptomics And Toxcast Data Identify Bioeffects In Zebrafish Embryos Exposed To Chemical Mixtures In An Effluent-Dominated Stream, Emma Meade
Theses and Dissertations
Wastewater treatment plant (WWTP) effluent-dominated streams provide critical habitat for aquatic organisms but also continually expose them to complex mixtures of pharmaceuticals and other contaminants of emerging concern (CECs) that can potentially impair growth, behavior, and reproduction. Limited toxicity data on the adverse biological impacts of in vivo exposure to these mixtures make it difficult to assess risk for aquatic organisms, particularly with respect to pharmaceuticals whose designed bioactivity often extends beyond conventionally monitored biological pathways. To address this knowledge gap, the goal of this thesis was to identify biomarkers of exposure to complex CEC mixtures relevant to specific chemicals …
Effects Of Wastewater Effluent On Fish Fin Morphology Of Larval Fathead Minnows (Pimephales Promelas) And Swimming Performance Of Smallmouth Buffalo (Ictiobus Bubalus), Seth Michael Bogue
Effects Of Wastewater Effluent On Fish Fin Morphology Of Larval Fathead Minnows (Pimephales Promelas) And Swimming Performance Of Smallmouth Buffalo (Ictiobus Bubalus), Seth Michael Bogue
Masters Theses
The Sangamon River flows across central Illinois and is mostly free flowing except in the city of Decatur where it is impounded to form Lake Decatur. The Sanitary District of Decatur (SDD) is located approximately three miles downstream of the Lake Decatur dam. For a significant portion of the year, the stretch of the Sangamon River downstream of SDD is dominated by effluent due to limited discharge from the Lake Decatur dam. This has resulted in heavy nutrient loading, most notably phosphorus, and elevated levels of nickel and other compounds in the downstream section of the river. Smallmouth buffalo ( …
Valorization Studies On Ice-Cream Wastewater And Whey Permeate, Maryam Enteshari
Valorization Studies On Ice-Cream Wastewater And Whey Permeate, Maryam Enteshari
Electronic Theses and Dissertations
Ever growing demand for dairy products in many countries has led to advancements in the manufacture of such products. Nowadays, revolutionary trends for high-protein dairy foods and drinks products have brought about new challenges from processing requirements and manufacturing aspects. Using different membrane processing has enabled dairy manufacturers to produce different fraction of milk proteins such as micellar caseins, ultra-filtered (UF) milk proteins, whey proteins concentrate (WPC), and micellar casein concentrate (MCC) to meet the nutritional needs with variety of milk product options. However, the installation of new processing lines and establishing further manufacturing steps requires more consumption of water …
Seasonal Temperature Changes In Three Midwestern Wastewater Streams And The Effects On Fish Assemblages And Physiology, Ryan William Sparks
Seasonal Temperature Changes In Three Midwestern Wastewater Streams And The Effects On Fish Assemblages And Physiology, Ryan William Sparks
Masters Theses
Midwestern United States undergo extreme temperature and precipitation fluctuations throughout the year, which leads to changing habitats within Illinois river systems. Wastewater treatment facilities have long been used to treat sewage and reduce the organic products in sewage before releasing it into aquatic environments. Wastewater treatment facilities must maintain optimal conditions, especially temperature, for reproduction and growth of facilitated bacteria that break down organic materials in wastewater. The objectives for this study were to determine the thermal effects of wastewater treatment facilities on receiving waters; and secondly, to investigate the influence of these wastewater facilities on fish abundance and assemblages. …
Application Of A Bioenergetics Framework For Assessing Sub-Lethal Effects Of Pollutants In The Freshwater Mussel Elliptio Complanata, Christopher G. Goodchild
Application Of A Bioenergetics Framework For Assessing Sub-Lethal Effects Of Pollutants In The Freshwater Mussel Elliptio Complanata, Christopher G. Goodchild
All Theses And Dissertations
Although biomarkers are frequently used to assess sublethal effects of contaminants, a lack of mechanistic linkages to higher-level effects limits the predictive power of biomarkers. Bioenergetics has been proposed as a framework for linking cellular effects to whole-animal effects. We investigated sublethal effects of exposure to wastewater treatment facility effluent in freshwater mussels in situ, thereby capturing ecologically relevant exposure conditions. Our study focused on the energetic biomarker AMP-activated protein kinase (AMPK), while also considering more traditional biomarkers like heat shock proteins (HSP70), and antioxidant enzymes (i.e., superoxide dismutase (SOD), glutathione-S-transferase (GST)). We examined biomarkers at mRNA and protein levels. …
The Effects Of Wastewater Effluent On A Fish And Amphibian Species, Anthony Sowers
The Effects Of Wastewater Effluent On A Fish And Amphibian Species, Anthony Sowers
All Dissertations
Wastewater effluents have been shown to contain a variety of anthropogenic compounds, many of which have endocrine-disrupting properties. While multiple laboratory studies have shown the effects of such compounds on an individual basis at elevated concentrations, little research has attempted to characterize the effects of exposure to environmentally relevant mixtures of endocrine disruptors. The current study examined the effects of long-term exposure to graded concentrations of wastewater effluent on the fathead minnow, Pimephales promelas, and the northern leopard frog, Rana pipiens. Fathead minnows were exposed from the larval stage through sexual maturity, while northern leopard frogs were exposed as eggs …
