PRP microspheres were found to be highly oleophilic as well as hydrophobic making it an ideal solution for hydrocarbon spills that contaminate water such as ocean spills, mangroves and marshes, and in groundwater aquifers. As a result, the powder was named “Petroleum Remediation Product.”
Sorbents collect specific liquids or gases depending on the composition of the material being used in the sorbent. Some of the most common sorbents used to clean oil spills are made from materials that are both oleophilic and hydrophobic, have high surface area through structural designs that include pores and capillaries, and draw in liquid through capillary action.

Booms used in oil spills can be seen as they rest on the surface of the water, but can have between 45 and 120 cm (18 to 48 inches) of material that hangs beneath the surface. [3] They are effective in calm water, but as wave height increases oil or other contaminants can easily wash over the top of the boom and render them useless.
In 2012, a study found that Corexit made the oil up to 52 times more toxic than oil alone, [12] and that the dispersant's emulsifying effect makes oil droplets more bio-available to plankton. [13] The Georgia Institute of Technology found that "Mixing oil with dispersant increased toxicity to ecosystems " and made the gulf oil spill worse.
Bioremediation of petroleum contaminated environments is a process in which the biological pathways within microorganisms or plants are used to degrade or sequester toxic hydrocarbons, heavy metals, and other volatile organic compounds found within fossil fuels. Oil spills happen frequently at varying degrees along with all aspects of the ...
An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution.The term is usually given to marine oil spills, where oil is released into the ocean or coastal waters, but spills may also occur on land.
Neither the protective gear, nor the manual were distributed to Gulf oil spill cleanup workers, according to FOIA requests obtained by GAP. [45] A study of 247 BP oil spill clean-up workers released in September 2013 by the American Journal of Medicine showed the workers were at an increased risk of developing cancer, leukemia and other ...
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]
