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 …
Springs Of The Arabian Peninsula: Historical Trends, Current Status And Human Impact In Saudi Arabia, Oman And Jordan, Kamal M. Aljohani
Springs Of The Arabian Peninsula: Historical Trends, Current Status And Human Impact In Saudi Arabia, Oman And Jordan, Kamal M. Aljohani
USF Tampa Graduate Theses and Dissertations
This research was conducted to update previous studies of the springs of the Arabian Peninsula (Saudi Arabia, Oman and Jordan). Approach: 76 springs were surveyed in between March and July 2018: 15 Saudi Arabia, 41 Oman and 20 Jordan to ascertain the current status, water quality and zooplankton benthos and fish communities. Investigation of the changes of biota and chemical parameters downstream from the springs source in Saudi Arabia. Results: Mercury exceeded the WHO and USEPA maximum contaminant level (MCL) in 63 of 76 springs, Aluminum exceeded MCL in 8 of 76 springs, and both were the common dissolved heavy …
Polycyclic Aromatic Hydrocarbon Metabolites As A Biomarker Of Exposure To Oil In Demersal Fishes Following The Deepwater Horizon Blowout, Susan Susan Snyder
Polycyclic Aromatic Hydrocarbon Metabolites As A Biomarker Of Exposure To Oil In Demersal Fishes Following The Deepwater Horizon Blowout, Susan Susan Snyder
USF Tampa Graduate Theses and Dissertations
The Deepwater Horizon blowout occurred on April 20th, 2010, releasing 4.9 million barrels of Louisiana crude oil into the Gulf of Mexico (GoM). Subsequent to the Deepwater Horizon blowout, sediment cores revealed oil on the northern GoM seafloor and abnormal skin lesions were seen in GoM fishes. Exposure to polycyclic aromatic hydrocarbons (PAHs), a component of crude oil, in fish has been associated with many sublethal effects, including cancer and population-level effects. Using a biomarker of exposure to PAHs, this thesis evaluates inter-species, temporal and spatial differences in exposure to hydrocarbon contamination between three species of fish with varying levels …
