What is oil spill?


Oil spills, as oil spills at sea are called, are events of enormous environmental impact. Understand its causes and consequences

If the ocean isn’t the usual blue-green color, something is usually wrong. While some algae can give the sea a reddish colour, if the waters are black, it is a sign that there has been an oil spill in the area.




This fossil-based raw material is widely used for the production of fuels or consumer goods, with petrol and plastics being examples of its derivatives. We know it’s burning fossil fuels it’s bad for the environment, but it’s not the only place where oil can be a problem. It is also responsible for the black tide phenomenon.

What causes the oil spill

Oil slicks can be caused by failures in the extraction, storage or transportation of oil. While it is still being extracted, explosions at deep-sea wells or accidents on the platforms where it is being harvested can already release tons of oil into the ocean. During transportation, improper storage or tanker accidents it can also release the liquid.

Since oil is made up of non-polar molecules, it doesn’t mix with water, which is a polar molecule. The result is large oil slicks that remain under the surface of the water, affecting the fauna and flora of the oceans.

There are records of oil leaks from the beginning of its exploration, still in the 19th century. The largest ever recorded in history, however, was not an accident: it happened during the Gulf War, when the Iraqi army set fire to reserves material in Kuwait as a combat strategy.

The consequences of oil slicks

An oil spill can last anywhere from weeks to several years, depending on the amount of oil spilled and ocean dynamics. During this time, the oil spots block sunlight from entering the water, preventing photosynthesis by algae and bacteria. The process affects the entire food chain, the basis of which is made up of these organisms.

Additionally, the oil can affect animals such as birds and marine mammals. It is extremely toxic if ingested and can act as a thermal insulator if it coats the body of these animals, causing hypo or hyperthermia – death from cold or heat.
