Chemical Dispersants

What are the effects on the wild life?
What are the effects of the dispersants on humans?
How well do they work on the oil?


  1. 1. In the original test, it was shown that the 8 dispersants reviewed by the EPA hadn't disrupted the endocrine systems of fish. The Corexit 9500 dispersant was even thought to have a low toxicity level to fish. In all 8 chemical mixes, the dispersants by themselves were far less toxic than a combination of oil and dispersant. The fish aren't even shown to retain the chemicals very longs, so they are generally safe from harm and for consumption.

    2. Because the fish aren't retaining the chemicals, they aren't being transfered up in the food chain, which means that the consumers won't be subject to danger. However, as with any chemical, prolonged exposure can be dangerous to you health.

    3. Even if the dispersants worked to a degree, there was so much of it pouring out into the ocean that it didn't make much of a difference. In addition, the dispersant mixed with oil was of a significant toxicity, so the risks would outweigh the benefits.
