Chemical and microbiological characterization of mangrove sediments after a large oil-spill in Guanabara Bay, RJ, Brazil

Seventeen months after a 1,3 million L oil spill into Guanabara Bay, analyses of mangrove sediments showed that the three sites closest to the spill remain highly polluted (> 10 mu g-g(-1) polyaromatic hydrocarbons). A fourth site was less polluted, from which most hydrocarbon degrading bacteria were isolated.
