ESTUDO DO FATOR DE BIOACUMULAÇÃO (BAF) NA ESPÉCIE SERRASALMUS SSP (PIRANHA) CAPTURADAS NA REPRESA DE TUCURUÍ- PARÁ

Abstract

This work has as main purpose to determine the
levels of bioaccumulation (BAF) of metals present in the
species Serrasalmus spp (Piranha) to evaluate the
bioaccumulation of metals, especially heavy metals due to
the damming of the Tocantins River to build the
hydroelectric plant Tucuruí - PA. The factor (BAF) was
calculated: Cd (11625.00), Zn (10890.00), Ca (950.10), Al (935.34), Mg (613.81), Sr (461.89 ), Cr (383.72), Ag
(275.36), Pb (104.84), Fe (69.67), Ba (63.72), Ni (52.86), Na (44.71). The metal that made the biggest factor was the
accumulation of Cd, this finding shows that although the
concentrations of Cd in tissue in the studied species, is on
average below the limit set by ANVISA, this metal is
bioaccumulative and can harm health the population that
uses this species to be considered a carcinogenic metal.
