Hepatobiliary Polycyclic Aromatic Hydrocarbons In Pelagic Fishes Of The Gulf Of Mexico, Madison R. Schwaab
Hepatobiliary Polycyclic Aromatic Hydrocarbons In Pelagic Fishes Of The Gulf Of Mexico, Madison R. Schwaab
USF Tampa Graduate Theses and Dissertations
Fisheries populations and their ecosystems are negatively impacted by both chronic and acute inputs of pollutants, including oil spills such as the Deepwater Horizon platform blowout in 2010 in the Gulf of Mexico (GoM). After Deepwater Horizon, toxicological studies of demersal fishes of the northern GoM were undertaken to characterize impacts and to establish baseline contaminant levels in the aftermath of the spill. In this study, I quantify polycyclic aromatic hydrocarbon (PAH) concentrations in eight pelagic fish species to demonstrate oil exposure differences between species, region and time. Analysis of biliary PAH metabolite equivalents using high performance liquid chromatography was …

Occurrence And Biological Effect Of Exogenous Steroids In The Elkhorn River, Nebraska, Usa, Alan Kolok, Daniel Snow, Satomi Kohno, Marlo Sellin, Louis Guillette
Daniel D Snow
Recent studies of surface waters in North America, Japan, and Europe have reported the presence of steroidogenic agents as contaminants. The current study has three objectives: 1) to determine if steroidogenic compounds are present in the Elkhorn River, 2) to determine if sediments collected from the Elkhorn River can act as a source of steroidogenic compounds to aquatic organisms, and 3) to determine if site-specific biological effects are apparent in the hepatic gene expression of fathead minnows. Evidence was obtained using three approaches: 1) deployment of polar organic chemical integrative samplers (POCIS), 2) deployment of caged fathead minnows, and 3) …
