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 …
Spatial And Temporal Extent Of A Subsurface Hydrocarbon Intrusion Following The Deepwater Horizon Blowout, Kathleen Watson
Spatial And Temporal Extent Of A Subsurface Hydrocarbon Intrusion Following The Deepwater Horizon Blowout, Kathleen Watson
USF Tampa Graduate Theses and Dissertations
The Deepwater Horizon (DWH) oil spill in the Gulf of Mexico (GoM) released an estimated 4.9 million barrels of oil between April 20, 2010 and July 15, 2010. An estimated 36% of the oil formed a neutrally buoyant intrusion, containing both dissolved compounds and oil microdroplets, between 1000 and 1300 m depth. This study used geographic information systems software, and data from water samples that were collected as part of the National Resource Damage Assessment (NRDA), to determine that an area of at least 1,600 km2 was exposed to DWH oil. Toxic BTEX (benzene, toluene, ethylbenzene, and …
