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 …
Polychlorinated Biphenyls, Organochlorine Pesticides, And Polycyclic Aromatic Hydrocarbons In Snapper (Family Lutjanidae) From Cuba And The Wider Gulf Of Mexico, Brigid E. Carr
USF Tampa Graduate Theses and Dissertations
The Snapper species assemblage is economically and environmentally important to all three countries bordering the Gulf of Mexico (GoM). Polycyclic aromatic hydrocarbons (PAHs), organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) were investigated in seven snapper species located in the GoM, with a specific focus on the those caught along the northwestern coast of Cuba. Hepatic samples were processed using QuEChERs extraction methodology and analyzed using gas chromatography with tandem mass spectrometry (GC-MS/MS). Nearly all fish included in this study contained detectable amounts of all three groups of these contaminants, regardless of location, and across all regions of the Gulf, indicating …
