Abstract

This study evaluated for the first time the concentrations of 10 metals in wild specimens of abalone, Haliotis tuberculata (Ht) (Linnaeus, 1758) from three sites along the southern Italian coast: Gulf of Catania (CT), the Northern Coast of Messina (ME) and the harbor of Villa San Giovanni (VSG). The species is commonly found in the area and has significant commercial value. Additionally, it is long lived, thus suitable as bioindicator of the environmental monitoring. The potential human health risks due to consumption of Ht have been assessed by estimated average daily intake (EDI) and target hazard quotient (THQ) of metals, respectively. In particular arsenic (As), cadmium (Cd), copper (Cu), chromium (Cr), iron (Fe), lead (Pb), manganese (Mn), mercury (Hg), selenium (Se) and vanadium (V) were quantified in the edible tissue of specimens by acid digestion of the samples and ICP-MS determination. The highest concentrations were found in CT sample area for most metals analyzed. Mean values for Pb, Cd and Hg were lower than the maximum levels (MLs) set for bivalve mollusks by Regulation (CE) no. 1881/2006 in all sites, and average intake values below the risk levels for human consumption.

Keywords: Abalone; EDI; Food safety; Heavy metals; THQ.
