Assembleia e Bioindicadores de Foraminíferos para Avaliação do Impacto Antropogênico na Baía de Guanabara, Rio de Janeiro, SE Brasil

Abstract

In January 2000, Guanabara Bay in Rio de Janeiro experienced a major oil spilling caused by a break down in one PETROBRAS oil pipeline. Over than 1.3 tons of fuel oil escaped into the bay water in the northern region. Studies of foraminiferal taphonomic assemblages in sediment samples collected on three periods in the same stations, before and after the spilling, were important for the pollution impact evaluation during eight years.
