Abstract: The institutional politic context of Brazil concerning the seaports require from government agencies, involved with environmental questions, an effort of public actions and policies that aim to adapt the Brazilian ports to quality parameters required by environmental national and international standards. This work is the consequences of this effort that resulted in an agreement signed between the Secretariat of Ports and IVIG/COPPE/UFRJ and has as aim develop a database system coupled to an information system (GIS) about environmental quality of sediment from the dredging activity of 18 Brazilian seaports. The project developed a method of validating the entire process of analysis of sediments for the years 2004 to 2010, which included the preparation of Systems MoniPort ® (Bando data) and MoniGeo® (SIG), with the overall objective of contributing to the improvement of environmental management of ports. It is emphasized that the results provided subsidies for the improvement of environmental legislation on the area. The work was divided into two phases, the first, completed in December 2011, presents the results of the level of contamination of sediments from the dredging and deepening of monitoring that will be presented in this article. The ports analyzed in this first phase were: Rio Grande, São Francisco do Sul, Santos, Rio de Janeiro, Salvador, Aratu; Recife, Suape and Belém.
The results form the basis MoniPort System®. These were also used by the Secretariat of Ports as input for revision of Brazilian legislation in this area, and as a tool for management environmental of ports in the process of environmental licensing of dredging activity. The work has a pioneering character, for the first time in Brazil the data about dredging were validated, organized and mapped the levels of contamination.
