Abstract

This paper discusses chemical and physical analyses of Paranagua Port’s dredged material based in the relevant dredging legislation in Brazil, CONAMA No 454/2012. It was analyzed samples before dredging activity of Paranagua Port`s berth. Most of samples had concentrations below in the Level 1 established by CONAMA Resolution No. 454/2012. However, considering the nature of these contaminations, we can suggest that losses during the operations of loading / unloading, storage and transfer of products in Paranagua Port, constitute sources of polluting materials into waters of the berth samples. Most of contamination may come from fertilizers because Paranagua Port exports grains and imports fertilizer to control food production.
