Abstract

Heavy metals have the ability to accumulate in living tissues throughout the food chain. Fish can become the main form of population transfer to these elements, since they are capable of bioaccumulation and bioconcentration. In order to investigate the bioaccumulation in fish in the Pontal of Bar - Patos Lagoon, in Pelotas, were selected three species abundant in the region, Micropogonias furnieri (Corvina), Mugil platanus (Tainha) and Netuma barba (Bagre). Samples of their muscles were analyzed to verify the contents of Al, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn. Samples in quintuplicate suffered HNO3/HCIO4 acid digestion, and the extracts analyzed by inductively coupled plasma - optical emission spectrometry (ICP-OES). The levels of chromium found in all species were above those established by Brazilian legislation (Decree-Law 55.871-65), which determines a maximum level tolerated for chromium 0.1 mg kg-1. The 82.46 ± 4.69% mg kg-1 of zinc in the species Netuma barba also exceeded the allowed limit. The cadmium concentrations found in the species Micropogonias furnieri, 0.92% ± 8.16% mg kg-1 were close to the limit. The other analytes were found at levels below those established by the Ministry of Health and ANVISA.
