Development of Corexit 9580—A Chemical Beach Cleaner

International Oil Spill Conference Proceedings, 1991
ABSTRACT Chemical beach cleaners can facilitate cleanups of oiled shorelines by improving the efficiency of washing with water. The improvement is a result of reduced adhesion of the oil coating, which makes it easier to remove from shoreline surfaces, thereby reducing washing time and lowering the temperature of the wash water needed to

Acute Effects of COREXIT EC9500A on Cardiovascular Functions in Rats

Journal of Toxicology and Environmental Health, Part A, 2011
These studies characterized cardiovascular responses after an acute inhalation exposure to COREXIT EC9500A, the oil dispersant used in the Deepwater Horizon oil spill. Male Sprague-Dawley rats underwent a single 5-h inhalation exposure to COREXIT EC9500A (average exposure level 27.12 mg/m(3)) or air.

Effects of corexit 9527 on the hatchability of mallard eggs

Bulletin of Environmental Contamination and Toxicology, 1979
The present paper reports the results of a study of the effects of Corexit 9527 dispersant, crude oil, and crude oil/Corexit 9527 mixtures on mallard duck (Anas platyrhynchos) embryos. Mallard eggs treated with 20 ul of crude oil, Corexit 9527, 30:1 oil/Corexit 9527, 5:1 oil/Corexit 9527, and 5 ul Corexit 9527 and 5:1 oil/Corexit 9527 had significantly

ACUTE AQUATIC TOXICITY OF THREE COREXIT PRODUCTS: AN OVERVIEW

International Oil Spill Conference Proceedings, 1997
ABSTRACT Corexit 9527, Corexit 9500, and Corexit 9580 have low (LC50 or EC50 > 100 ppm) to moderate (LC50 or EC50 > 1 to 100 ppm) toxicity to most aquatic organisms in laboratory tests; however, the experimental species, temperature, and exposure duration can significantly affect measurements of toxicity.

The effects of Esso Corexit 9527 on the fertilizing capacity of spermatozoa

Marine Pollution Bulletin, 1977
Abstract The water-soluble oil dispersant Esso Corexit 9527 has earlier been found to interfere, even in low concentrations, with fertilization and development. Further studies of the effect on sea urchin spermatozoa demonstrate that Corexit 9527 gives negative biological effects in concentrations down to 0.0003 ppm.

The dispersant Corexit 9500 and (dispersed) oil are lethal to coral endosymbionts

Marine Pollution Bulletin
Endosymbionts (Symbiodiniaceae) play a vital role in the health of corals. Seawater pollution can harm these endosymbionts and dispersants used during oil spill cleanup can be extremely toxic to these organisms. Here, we examined the impact of oil and a specific dispersant, Corexit-9500, on two representative endosymbionts - Symbiodinium and ...

A Comparative Assessment of the Aquatic Toxicity of Corexit 9500 to Marine Organisms

Archives of Environmental Contamination and Toxicology, 2018
The use of chemical dispersants during oil spill responses has long been controversial. During the Deepwater Horizon (DWH) oil spill, 1.8 million gallons of dispersant, mainly Corexit 9500, were applied in offshore waters to mitigate the human health and coastal environmental impact of surface oil contamination.

Toxicity study of the oil dispersant Corexit 9527 on Macrobrachium rosenbergii (de Man) egg hatchability by using a flow-through bioassay technique

Environmental Pollution, 1995
The effect of the oil-spill dispersant Corexit 9527 on egg-hatching rate of Macrobrachium rosenbergii (de Man) was studied by using an innovated flow-through bioassay technique. This bioassay method relies on the fact that M.

Microbial response to crude oil and Corexit 9527: SEAFLUXES enclosure study

Microbial Ecology, 1985
The response of marine bacteria to Corexit 9527, with and without Prudhoe Bay crude oil labeled withn-(1-(14)C)hexadecane, in a temperate pelagic environment was monitored over 22 days using controlled ecosystem enclosures. The results indicated that Corexit and Corexit-dispersed crude oil stimulated bacterial production by serving as substrates and/or

Membrane filtration of crude oil emulsions stabilized by Corexit 9500 dispersant

, 2018
During the 2010 Deepwater Horizon oil spill, nearly 800 million liters of oil were released into the Gulf of Mexico polluting the deep ocean and more than 1600 km of the Gulf\u2019s shoreline.
