Trace elements were measured in the edible tissues of target marine species (Sardina pilchardus, Mullus barbatus, Mullus surmuletus, Merluccius merluccius and Parapenaeus longirostris) collected in some of the main ports of the Sicilian coast (southern Italy) in order to evaluate the potential human health risk associated to their consumption. Cadmium, Pb and Hg were below the tolerable limits reported by the European Union in foodstuffs (Commission Regulation (EC) 1881/2006) except for Hg in P. longirostris from one sampling site. The health risk for consumers was assessed both for adults and children calculating the estimated weekly intake (EWI), the target hazard quotient (THQ) and the lifetime cancer risk (CR) for each element. The EWI did not exceed the provisional tolerable weekly intake (PTWI) recommended by the European Food Safety Authority and THQs were < 1 in most cases. Further, the probabilistic distributions of health hazard were evaluated through Monte-Carlo simulation which confirmed a non-carcinogenic risk. With some exceptions related to As exposure, the results obtained definitively confirm the goodness of the fishery commercial resources in one of the most important seafood market of the central Mediterranean Sea and represent a positive data for the assessment of the good environmental status for descriptor 9 of the Marine Strategy Framework Directive in this area of the basin.
