Oil dispersant mechanism of action. An oil dispersant is a mixture of emulsifiers and solvents that helps break oil into small droplets following an oil spill.Small droplets are easier to disperse throughout a water volume, and small droplets may be more readily biodegraded by microbes in the water.
This is a reverse-chronological list of oil spills that have occurred throughout the world and spill(s) that are currently ongoing. Quantities are measured in tonnes of crude oil with one tonne roughly equal to 308 US gallons , 256 Imperial gallons , 7.33 barrels , or 1165 litres .

By comparison, Corexit, the oil dispersant used in the Deepwater Horizon oil spill, is rated at 54.7% effective against South Louisiana crude oil and three times as lethal to silverfish and more than twice as lethal to shrimp. [5] On May 20, US Polychemical Corporation was reported to have received an order from BP for Dispersit SPC 1000. [6]
Oil spills happen frequently at varying degrees along with all aspects of the petroleum supply chain, presenting a complex array of issues for both environmental and public health. [1] While traditional cleanup methods such as chemical or manual containment and removal often result in rapid results, bioremediation is less labor-intensive ...
