Assessment of health risk related to the ingestion of trace metals through fish consumption in Todos os Santos Bay.

This study was carried out to evaluate the concentration of trace elements (As, Cd, Cu, Pb, and Zn) in the muscle of carnivorous fish species from three different areas of Todos os Santos Bay (BTS), Bahia State, Brazil. Trace elements were analyzed using inductively coupled plasma-optical emission spectrometry (ICP-OES), and consumption rates advisory for minimizing chronic systemic effects in children and adults were estimated. As concentrations in fish samples from Jiribatuba were higher than legal limits set by FAO, and Cd concentrations in fish from Iguape Bay were high in comparison with FAO and EC. This study provides information about the fish consumption limits, considering the elements concentrations observed in the analyses, in particular As and Cd, necessary for minimizing potential health risks.
