Sublethal Effects Of Crude Oil And Chemical Dispersant On The Eastern Oyster (Crassostrea Virginica) At Multiple Life History Stages, Sara Marie Garcia

Graduate Theses and Dissertations

Oil spills in the marine environment can threaten vulnerable ecosystems that support ecologically and economically significant organisms, such as the eastern oyster (Crassostrea virginica), in coastal habitats. The use of chemical dispersant (Corexit 9500) was applied as a cleanup effort in response to the Deepwater Horizon blowout to minimize crude oil slicks, but also resulted in increased concentrations of polycyclic aromatic hydrocarbons in the water column. The effects of increased soluble fractions of crude oil and dispersant components may be harmful to marine organisms. This study aimed to investigate possible sublethal impacts to the eastern oyster at multiple life history ...
