"A common ingredient in human laxatives and in the controversial dispersants that was used to break down oil from the BP Deepwater Horizon oil spill is still being found in tar balls four years later along Gulf Coast beaches including Perdido Key.

This finding in a new study contradicts the message that the chemical dispersant quickly evaporated from the environment, which BP and EPA officials were telling a public who grew outraged over the widespread use of the chemicals in the Gulf of Mexico in the weeks following the April 20, 2010, oil spill disaster.

More than 1.8 million gallons of chemical dispersant was used on oil slicks and injected subsurface to prevent oil from fouling beaches and marshes."
