Biodegradation of Crude Oil and Corexit 9500 in Arctic Seawater [PDF]

Frontiers in Microbiology, 2018
The need to understand the biodegradation of oil and chemical dispersants in Arctic marine environments is increasing alongside growth in oil exploration and transport in the region. We chemically quantified biodegradation and abiotic losses of crude oil

Microbial response to the MC252 Oil and Corexit 9500 in the Gulf of Mexico [PDF]

Frontiers in Microbiology, 2012
The Deepwater Horizon spill released over 4.1 million barrels of crude oil into the Gulf of Mexico. In an effort to mitigate large oil slicks, the dispersant Corexit 9500 was sprayed onto surface slicks and injected directly at the wellhead at water ...

Mesopelagic microbial community dynamics in response to increasing oil and Corexit 9500 concentrations.

PLoS ONE, 2022
Marine microbial communities play an important role in biodegradation of subsurface plumes of oil that form after oil is accidentally released from a seafloor wellhead.

Toxicity of dispersant Corexit 9500A and crude oil to marine microzooplankton

Ecotoxicology and Environmental Safety, 2014
In 2010, nearly 7 million liters of chemical dispersants, mainly Corexit 9500A, were released in the Gulf of Mexico to treat the Deepwater Horizon oil spill. However, little is still known about the effects of Corexit 9500A and dispersed crude oil on microzooplankton despite the important roles of these planktonic organisms in marine ecosystems.

Trace analysis of surfactants in Corexit oil dispersant formulations and seawater [PDF]

Deep-Sea Research Part II: Topical Studies in Oceanography, 2016
After the April 2010 explosion on the Deepwater Horizon oil rig, and subsequent release of millions of barrels of oil, two Corexit oil dispersant formulations were used in unprecedented quantities both on the surface and sub-surface of the Gulf of Mexico.

How the dispersant Corexit impacts the formation of sinking marine oil snow

Marine Pollution Bulletin, 2017
The vertical transport of sinking marine oil snow (MOS) and oil-sediment aggregations (OSA) during the Deepwater Horizon (DwH) spill contributed appreciably to the unexpected, and exceptional accumulation of oil on the seafloor. However, the role of the dispersant Corexit in mediating oil-sedimentation is still controversial.

Corexit-EC9527A Disrupts Retinol Signaling and Neuronal Differentiation in P19 Embryonal Pluripotent Cells. [PDF]

PLoS ONE, 2016
Corexit-EC9500A and Corexit-EC9527A are two chemical dispersants that have been used to remediate the impact of the 2010 Deepwater Horizon oil spill. Both dispersants are composed primarily of organic solvents and surfactants and act by emulsifying the ...

Comparison of Acute Aquatic Effects of the Oil Dispersant Corexit 9500 with Those of Other Corexit Series Dispersants

Ecotoxicology and Environmental Safety, 1996
The acute aquatic toxicity of a new Corexit series dispersant, Corexit 9500, was evaluated and compared with that of others in the series using early life stages of two common nearshore marine organisms: the red abalone (Haliotis rufescens) and a kelp forest mysid (Holmesimysis costata).

1H-NMR metabolomic study of whole blood from hatchling loggerhead sea turtles (Caretta caretta) exposed to crude oil and/or Corexit [PDF]

Royal Society Open Science, 2017
We used proton nuclear magnetic resonance spectroscopy (1H-NMR) to evaluate metabolic impacts of environmentally relevant crude oil and Corexit exposures on the physiology of hatchling loggerhead sea turtles (Caretta caretta).

Comparative Proteomics of Marinobacter sp. TT1 Reveals Corexit Impacts on Hydrocarbon Metabolism, Chemotactic Motility, and Biofilm Formation

Microorganisms, 2020
The application of chemical dispersants during marine oil spills can affect the community composition and activity of marine microorganisms. Several studies have indicated that certain marine hydrocarbon-degrading bacteria, such as Marinobacter spp., can
