Oil's negative effects last far longer, scientists now say, and the findings should be a wake-up call for better environmental research and protection.
The study, conducted by a University of North Carolina at Chapel Hill researcher and colleagues, involved synthesizing results of numerous more specialized but revealing investigations of the Alaskan disaster's impact on various plant and animal species.
"These simply astounding findings have extremely important implications for environmental management," said principal investigator Dr. Charles H. Peterson, Alumni Distinguished professor of marine sciences at the University of North Carolina at Chapel Hill. "They show the environmental consequences of the Exxon Valdez oil spill went far beyond the more than 250,000 seabirds, thousands of marine mammals and countless numbers of other coastal marine organisms killed in the first days, weeks and months."
A report on the work appears in the Dec. 19 issue of the journal Science.

"Studies we reviewed and synthesized showed that oil has persisted in surprisingly large quantities for years after the Exxon Valdez spill in subsurface reservoirs under course intertidal sediments," Peterson s
