Avaliação de Metais ( Al, As, B, Ba, Bi, Ca, Cd, Co, Cr,Cu, Fe,K, Mg, Mn, Mo, Na, Ni, P, Pb, Sb, Sc, Se, Sn ,Sr, V, Zn) em Liposarcus pardalis (Bodó) e Prochilodus Cearensis (Curimatã)

Abstract

The fish (bodó) Liposarcus Pardalis and (curimatã) Prochilodus Cearensis are common in the dams of Ceará’s countryside and quite consumed by the population. The objective of this study was to determine the concentrations of metals (Al, As, B, Ba, Bi, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, P, Pb, Sb, Sc, Se, Sn ,Sr, V, Zn). As well as the presence of essencial metals or minerals in the organism (have a physiological function), environmental microcontaminants (heavy metals), and essential metals and the same time contaminates (required for the body and toxic at high concentrations). Digestion of the samples was done by wet method and an Optical Emission Spectrophotometer with Inductively Coupled Plasma (ICP-OES) was used. After the analysis, it was found that the essential metals of the analyzed fish have a concentration in the appropriate limits for humans and the heavy metals did not exceed limits established by Brazilian legislation and are therefore suitable for consumption.
