Several alternatives have been proposed in order to minimize the harmful effects that the disposal of metals in Amazon rivers. The objective of this work was to study the use of acai (Euterpe Oleracea Mart.) to remove metals in surface Waters. Samples were collected from 19 sampling stations in the rivers Guama, Barcarena and Guajará Bay. The acai charcoal was prepared and used in the removal of metals using a low cost filter. The river water quality was performed using multiparameter probes and ICPOES in the analysis of metals. The results for water quality showed that the rivers assessed retain characteristics of preserved rivers with all parameters (average) in accordance with the 357/05 CONAMA Resolution. The use of acai coal showed variation from 41.67% to 67.46% in metals removal from water surface and can be an inexpensive alternative for use in low cost filters.
