419,000 gallons of oil spilled into Mississippi River

While we sleeping last night a large ecological disaster happened in the Mississippi river around New Orleans. Close to a half million gallons of oil were spilled into the Big River when a barge collided with a Liberian oil tanker. CNN has the story:

The spill is much smaller than the ones that followed Hurricane Katrina in 2005, when the Coast Guard estimated that more than 7 million gallons of oil were dumped into the Mississippi and nearby waterways.

But Wilma Subra, a chemist who advises the Louisiana Environmental Action Network, said the oil could affect wildlife and work its way up the food chain into residents, many of whom fish for subsistence.

"This is a spill that occurred in a very urban area, and it can impact a very large number of people," she said.

The oil, widely used as marine fuel, is heavier than diesel but lighter than crude, and it is likely to stick to rocks, trees and wildlife, Stroh said.
