Evaluation of differential cytotoxic effects of the oil spill dispersant Corexit 9500
Life Sciences, 2014The British Petroleum (BP) oil spill has raised several ecological and health concerns. As the first response, BP used a chemical dispersant, Corexit-9500, to disperse the crude oil in the Gulf of Mexico to limit shoreline contamination problems. Nevertheless, portions of this oil/Corexit mixture reached the shoreline and still remain in various Gulf ...

Oil biodegradation: Interactions of artificial marine snow, clay particles, oil and Corexit
Marine Pollution Bulletin, 2017 During the Deepwater Horizon (DwH) oil spill, interactions between oil, clay particles and marine snow lead to the formation of aggregates. Interactions between these components play an important, but yet not well understood, role in biodegradation of oil in the ocean water.

Corexit 9500 Enhances Oil Biodegradation and Changes Active Bacterial Community Structure of Oil-Enriched Microcosms [PDF]
Applied and Environmental Microbiology, 2017 To better understand the impacts of Corexit 9500 on the structure and activity levels of hydrocarbon-degrading microbial communities, we analyzed next-generation 16S rRNA gene sequencing libraries of hydrocarbon enrichments grown at 5 and 25°C using both

Our study examined the effects of Corexit 9500 and sediment on microbial mineralization of specific aliphatic and aromatic hydrocarbons found in crude oil. We also measured gross mineralization of crude oil, dispersed crude oil and dispersant by a marine microbial consortium in the absence of sediment.

Aquatic toxicity of two Corexit® dispersants
Chemosphere, 2000The oil spill dispersants, Corexit 9500 and Corexit 9527 have low to moderate toxicity to most aquatic species in laboratory tests. Toxicity estimates are significantly affected by test variables such as species, lifestage, exposure duration, and temperature.

Photochemical degradation of Corexit components in ocean water
Chemosphere, 2014Due to the large quantities of dispersants used during the Deepwater Horizon spill in 2010, there were immediate concerns with regards to the fate and transport of the mixture in ocean waters. Direct and sensitized photolysis experiments were carried out for two compounds chosen as surrogates for the Corexit mixture (9500 and 9527) that were applied to

Response of larval frogs to Corexit 9500
Toxicological & Environmental Chemistry, 2012The use of dispersants in the Gulf of Mexico has created a number of environmental and human health concerns, chief among them are questions regarding the potential impact of Corexit 9500 on the health and fitness of Gulf wildlife. These studies were designed to use a biological toxicity test during post-fertilization and early development to evaluate ...

Deleterious effects of corexit 9527 on fertilization and development
Marine Pollution Bulletin, 1976Abstract The effect of the water soluble oil dispersant Corexit 9527 was tested on larvae from several species of sea urchins and marine fishes. Severe effects in fertilization and development were registered often resulting in pathological larvae and rapid cytolysis. The combination of Corexit 9527 with oil was found to be even more dangerous to the
