Worrying New Signs of BP's Oil in Gulf
When the Deepwater Horizon blew April 2010, oil spill experts said it was a disaster that will keep on giving for years to come, and the evidence of that truth is piling up.
A study released in the Proceedings of the National Academies of Science last week revealed that petroleum toxins from Deepwater Horizon have altered the cellular functions of the Gulf killifish, or cocahoe. This wetlands minnow is a prime a food source for valuable sports species such as redfish, speckled trout, flounder and drum. The impacts observed are predictive of disruption in reproduction and larvae survival, the authors reported. The complete study can be found here.
One day later, the U.S. Coast Guard acknowledged that oil sheens spotted near the site of the Deepwater Horizon blow-out may be coming from the well that was supposedly capped a year ago.
Anglers and environmental groups have been reporting sheens in the area for months, but authorities downplayed their relevance until samples analyzed by oil experts at Louisiana State University confirmed they were coming from the Macondo well.
