Cytotoxicity of Corexit-9500 and Corexit-9527.
P19 cells exposed to dispersants for 7 or 30 hours were measured for viability using the MTT assay. Relative Cell Viability was calculated by normalizing the MTT readings relative to the control cells (no Corexit exposure), which were set to be 1.

The eastern oyster Crassostrea virginica is an ecologically and economically important species that is vulnerable to oil pollution. We assessed sublethal effects of soluble fractions of crude oil alone (WAF) and crude oil in combination with Corexit 9500

Abstract The production of extracellular polymeric substances (EPS) by planktonic microbes can influence the fate of oil and chemical dispersants in the ocean through emulsification, degradation, dispersion, aggregation, and/or sedimentation. In turn, microbial community structure and function, including the production and character of EPS, is ...

Data_Sheet_1_Biodegradation of Crude Oil and Corexit 9500 in Arctic Seawater.docx
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

Natural and unnatural oil slicks in the Gulf of Mexico
Abstract When wind speeds are 2–10 m s−1, reflective contrasts in the ocean surface make oil slicks visible to synthetic aperture radar (SAR) under all sky conditions. Neural network analysis of satellite SAR images quantified the magnitude and distribution of surface oil in the Gulf of Mexico from persistent, natural seeps and from the Deepwater ...

Practical Considerations and Challenges Involved in Surfactant Enhanced Bioremediation of Oil
Surfactant enhanced bioremediation (SEB) of oil is an approach adopted to overcome the bioavailability constraints encountered in biotransformation of nonaqueous phase liquid (NAPL) pollutants. Fuel oils contain n‐alkanes and other aliphatic hydrocarbons, monoaromatics, and polynuclear aromatic hydrocarbons (PAHs).

Abstract The Deepwater Horizon (DWH) oil spill in the NE Gulf of Mexico in 2010 was the largest accidental spill globally. During and after the spill, oil was incorporated into marine snow (marine‐oil‐snow or MOS) and sedimented to the seafloor, accounting for ∼21% of the oil released.

Much oil spill research has focused on fertilizing hydrocarbon oxidising bacteria, but a primary limitation is the rapid dilution of additives in open waters. A new technique is presented for bioremediation by adding nutrient amendments to the oil spill using thin filmed minerals comprised largely of Fullers Earth clay.

The effect of Corexit-9527 on retinoid-induced Hoxa1 gene expression in P19 cells.
(A) Corexit-9527 inhibited ROH-induced Hoxa1 expression. P19 cells were exposed to the indicated concentrations of Corexit-9527 for 1 or 24 hr followed by 0.3 μM ROH for additional 6 hr.

A New Fluorescence Imaging Method to Evaluate Different Oil Types and Their Concentrations in Water
A novel fluorescence imaging technique enables accurate quantification of oil‐in‐water concentrations (5–500 ppm) and droplet size distributions without the use of additives. Optimized emulsification (14 000 rpm, 90 s) ensures stable samples, whereas advanced image analysis algorithms enable correlation of fluorescence signals with different oil types ...
