The most harmful chemicals used in the BP oil spill clean-up effort were dispersants, including Corexit. Dispersants work by breaking up oil to cause it to sink in the water, where bacteria can naturally consume the droplets. However, though the chemicals were approved by the US Environmental Protection Agency, scientists argue that dispersants are toxic to wildlife, and increase oil’s toxicity. Simply put, dispersants prevent oil from washing up on shore, but can cause harmful effects to marine life. However, the use of dispersants causes short-term damage and prevents long-term damage by oil to the coast.
