The Santos estuarine system is one of the main estuaries of Brazil, holding significant economic and industrial importance. In order to evaluate current levels of contamination in the area, sediment samples from the Santos Estuary and the Bertioga channel were analyzed for aliphatic and aromatic hydrocarbons and sterols. Results indicated high concentrations of polycyclic aromatic hydrocarbons (PAHs) in both Santos estuary (889.5-30,963 ng g-1) and Bertioga channel (123.9-6519 ng g-1), with PAHs mainly related to pyrolytic sources in the Santos region, and transported to the Bertioga channel. N-alkane concentrations ranged from 8.2 to 76.9 mu g g-1, and showed influences from both natural sources, mainly related to the adjacent mangrove vegetation (in the Bertioga channel), and petroleum inputs (in Santos area). Fecal sterols were found widespread (0.03-10.42 mu g g-1), indicating input of urban sewage in the majority of samples, being related to areas of irregular domestic waste discharge. These results indicated that levels of contamination are still high in the area and even higher than some of the previous studies, reafirming the need for a long-term monitoring plan and policies to control polluents emission and dispersion.
