HEAVY METALS CONTAMINATION IN FISH OF THE LIGURIAN SEA

Abstract

Aim of this investigation was to evaluate heavy metals contamination (mercury, cadmium and lead) in fish and shellfish from Ligurian Sea. 58 muscle samples (45 fish and 13 shellfish) were collected and analyzed. 20 samples exceeded the maximum residue limits (MRLs) set by regulation for mercury (16 fish and 4 shellfish samples), while only one fish sample was not consistent with the MRL for lead. Therefore, 35,8% of Ligurian fishing turned out to be not adequate and potentially harmful for consumers. In order to estimate the real risk for human health it is necessary to enforce this study, correlating the results with fish species and with the effective fish consumption.
