“…In 2007 swordfish samples from the Ionian Sea, PBDE values ranged from 150 to 1,320 pg g -1 f.w., and in bluefin tuna from the same area PBDEs ranged between 120 and 1,150 pg g -1 f.w. (8). The values found in this study are comparable with PBDE concentrations in fish (88-1,019 pg g -1 f.w.)…”

“…5). This decrease may be due to the fact that in the Mediterranean, the size of fish of these two species is gradually being reduced as a result of overfishing (younger, less polluted), but also to potential reproductive alterations in large pelagic fish in this basin resulting from high levels of accumulation of endocrine disruptors in these two species [7,8,10].…”

“…More recently, other pollutants with endocrine disruptor actions have been found in food products, posing a risk of adverse effects to human health and the environment; they include polybrominated diphenyl ethers (PBDEs). These contaminants are increasingly found in Mediterranean ecosystems, while there are serious shortcomings in terms of availability of data on aspects such as the contribution of various food products to human exposure [8][9][10][11]. Polybrominated diphenyl ethers (PBDEs) are a class of emerging substances used worldwide as flame retardants.…”

“…For this reason, this study reports on the presence and levels of PBDEs in commercial food in the Province of Siena (Italy), with a particular attention to food products of marine origin, in order to evaluate risk for humans due to food consumption. Published papers on the presence of PBDEs in food in Italy are scarce or nonexistent, although there is information available on their presence in the Mediterranean marine environment [8,[10][11], and their threat to human health is well known [20][21][22][23][24][25]…”

This study reports on the presence and levels of polybrominated diphenyl ethers (PBDEs) in food items collected during the period 2004-2010 in commercial food shops in Siena (Southern Tuscany, Central Italy), in order to evaluate risk to humans due to food consumption. We have considered the following eight PBDE congeners to be of primary interest: BDE28, BDE47, BDE99, BDE100, BDE153, BDE154, BDE183 and BDE209. The overall results clearly show a strong difference in concentration of PBDEs between seafood and food from the terrestrial trophic web. PBDE concentrations in commercial food from terrestrial origin vary from an average of 156 pg g -1 fat in chicken breast (6 pg g -1 fresh weight) to an average of 404 pg g -1 fat in butter (125 pg g -1 f.w.). In seafood, average values are comprised between 174 pg g -1 f.w. in hake to 692 pg g -1 f.w. in swordfish. In several samples of swordfish PBDE values are higher than 1 ng g -1 f.w. If we consider PBDE congeners individually, BDE47 is the predominant one in seafood, with percentages above 50% in all species. In commercial food of terrestrial origin, BDE47 is predominant in beef, pork, bacon, butter and sausage (27%-35%), followed by BDE209 (25%-28%). In chicken breast, eggs and cow's milk, BDE209 is predominant (28%-32%) followed by BDE47 (25%-30%). The level of PBDEs found in bluefin tuna and swordfish, considering their importance in the human diet, suggests the need for particular care in our food choices.

In this paper, the presence and amount of mercury and polychlorobiphenyls (PCBs) were determined in 23 bluefin tuna samples collected in the spring of 2012 in Porto Scuso (South West Sardinia, Italy) and Villa Putzu (South East Sardinia, Italy) in order to assess the current levels of these two contaminants in fish muscle and the consequent risk to humans consuming said fish. Values of polychlorobiphenyls in bluefin tuna muscle vary between 0.155 and 1.403 mg/kg f.w.; the average of PCBs in tuna muscle is 0.732 mg/kg f.w. With regard to PCBs the presence of more elevated concentrations is confirmed in larger fish. The results regarding mercury in muscle show an average of 0.660 mg/kg f.w. and mercury values vary between 0.140 f.w. and 2.211 mg/kg f.w.; for mercury as well, the highest concentrations were found in the largest bluefin tuna. Six samples, 26% of total, contained more than 1 mg/kg f.w., which is the maximum level set by the European Commission (EC, Regulation n. 1881/2006) for this species. Mercury, in particular methylmercury, poses a risk to public health, therefore, taking into account the important nutritional contribution that tuna fish makes to the diet, it is advisable that women of childbearing age, pregnant and breastfeeding women as well as young children strictly limit their consumption of tuna from this area of the Mediterranean.
