Study Links BP Oil Spill To Dolphin Deaths
"I've never seen such a high prevalence of very sick animals – and with unusual conditions such as the adrenal hormone abnormalities," Lori Schwake, the study's lead author, said in a statement.
The scientists caught, examined and released about 30 bottlenose dolphins from Barataria Bay in 2011, one year after the disaster. The area was one of the most heavily oiled areas following the April 2010 blowout of BP's deepwater well, that killed 11 workers and spewed millions of barrels of crude oil into the Gulf.
Government scientists and conservation groups had been concerned from the outset about the effects on marine life of the vast amounts of oil that entered the water.
