Oil still musseling into food chain.
The effective protection afforded by these bivalve communities suggests that this unweathered oil is "likely to persist for a long time," he says, permitting the shellfish to accumulate high concentrations of hydrocarbons. The mussels themselves do not appear to be suffering, he notes, but their contamination may prove toxic to humans and others. Indeed, he speculates, this contamination may explain why some key mussel consumers-such as otters, harlequin ducks, and certain shore birdscontinue to suffer unabated oil-related reproductive difficulties despite low concentrations of petroleum in their water and on their home beaches.
