Heavy metals in environment

Fish and seafood may represent risk for human health since they can accumulate contaminants from aquatic environment and magnify them up the food chain. The purpose of this study was to analyze and evaluate the levels of aluminum, zinc, iron, manganese, cobalt, copper, arsenics, selenium, cadmium, barium, lead and bismuth in 11 fish species (Salmo salar, Sardinella brasiliensis, Pomatomus saltatrix, Micropogonias furnieri, Cynoscion leiarchus, Caranx crysos, Priacanthus arenatus, Mugil cephalus, Genypterus brasiliensis, Lopholatilus villarii and Pseudopercis numida) captured at Rio de Janeiro State Coast, Brazil. Concentration ranges (mg kg−1 of wet weight) of the selected elements were compared with those reported in other studies. In some cases, comparison of certain elements in the same fish species was difficult due to the lack of data. Aluminum concentration was significantly high in all samples and only M. cephalus, C. leiarchus e C. crysos presented arsenic concentrations below 1 mg kg−1, limit recommended by Brazilian legislation.
