Consider the following statements about oil spilling remediation techniques:

Skimmers are devices used for physically separating spilled oil from the water’s surface.

Oil zapper is a burning in-situ method to remove up to 98% of an oil spill.

Bioremediation refers to the use of specific microorganisms to remove oil spill.

Which of the statements given above is/are correct?

Question

Bioremediation refers to the use of specific microorganisms to remove any toxic or harmful substances. Bacteria are used to clean surface oil. Eg Oil Zapper by TERI.
Better biodegradable emulsifiers may also be used for better mitigation of problems.
Skimmers are devices used for physically separating spilled oil from the water’s surface.
Floating boomscan be placed around the source of the spill or at entrances to channels and harbours to reduce the spreading of an oil slick over the sea surface.
Using various sorbents that absorb the oil from the water. Sorbents are materials that soak up liquids by either absorption (pulling in through pores) or adsorption (forming a layer on the surface).
Dispersal agents are chemicals that are sprayed upon the spill with the help of aircraft and boats, which aid the natural breakdown of oil components
Burning In-situ method can effectively remove up to 98% of an oil spill, which is more than most of the other methods.
