Resumo
Santos-São Vicente Estuarine System is a highly populated coastal zone in Brazil and where it is located
the major port of Latin America. Historically, port activities, industrial and domestic effluents discharges
have constituted the main sources of contaminants to estuarine system. This study aimed to assess the
recent status of sediment quality from 5 zones of Port of Santos by applying a lines-of-evidence approach
through integrating results of: (1) acute toxicity of whole sediment and chronic toxicity of liquid phases;
(2) grain size, organic matter, organic carbon, nitrogen, phosphorus, trace metals, polycyclic aromatic
hydrocarbons, linear alkylbenzenes and butyltins; (3) benthic community descriptors. Results revealed a
gradient of increasing contamination for metals and organic compounds, alongside with their
geochemical carriers. Sediment liquid phases were more toxic compared to whole sediment. Low
number of species and individuals indicated the impoverishment of benthic community. The use of sitespecific sediment quality guidelines was more appropriate to predict sediment toxicity. The integration
of results through Sediment Quality Triad approach and principal component analysis allowed observing
the effects of natural stressors and dredging on sediment quality and benthic distribution. Even with
recent governmental efforts to control, pollution is still relevant in Port of Santos and a threat to local
ecosystems.
