Heavy metals in Mugil cephalus (Mugilidae) from the Ligurian Sea (North-West Mediterranean, Italy).
Pb, Cd and Hg in muscles of flathead mullet (Mugil cephalus), collected from Bocca di Magra, La Spezia (Ligurian Sea, Mediterranean Sea, Italy), were determined using graphite furnace atomic absorption spectrometry after microwave digestion for Pb and Cd and direct mercury analyser for Hg. Average Pb concentrations varied in the range 0.20-0.24 mg/kg, whereas Cd and Hg levels were negligible. None of the tested 200 samples exceeded the European regulatory limits as set by EC 1881/2006 and 420/2011. Metal concentrations in fish muscles were assessed for human consumption according to provisional tolerable weekly intake. The estimated values of Pb, Cd and Hg in M. cephalus's edible parts in this study were below the values established by the Joint WHO/FAO Expert Committee on Food Additives. Therefore, it can be concluded that there is no health problem in human consumption.
