Metal accumulation in tissues of sharks from the Bahía Blanca estuary, Argentina

Total mercury, cadmium, and zinc accumulation was studied in muscle and liver of three species of shark from the Bahia Blanca estuary, Argentina. The mercury concentrations were similar in both muscle (range: 0·77–2·99 μg/g) and liver (0·79–2·26 μg/g) of the analyzed species. Concentrations of cadmium and zinc were higher in liver than in muscle. The frequency distributions of metal concentrations were found to be log-normal. The metal...
