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.

Cleanup and recovery from an oil spill is difficult and depends upon many factors, including the type of oil spilled, the ...
When a ship inadvertently spills oil, it’s big news. But according to an investigation by the Outlaw Ocean Project, a nonprofit journalism organization based in Washington, D.C., cumulatively ...
One of the significant environmental impacts of oil exploration is the contamination of aquatic ecosystems through oil spills and seepages. In some areas, such as the Amazon, oil is even used to suppress dust on roadways, causing contaminated runoff to enter nearby water bodies. This creates direct human health risks, as many people, including ...
Little has changed in how oil spills are cleaned up, but scientists are working on new tools, including sponges that can absorb oil in water, to respond to disasters. These sponges can hold more ...
Surf scoter covered in oil as a result of the 2007 San Francisco Bay oil spill. Exposure to oil (petroleum) can result in both external and internal damage to animals. It has the greatest impact on bird species, aquatic mammals, and other aquatic organisms. Affected wildlife can usually be identified via visual inspection, and can be treated if ...
