Total mercury concentrations were measured in the muscle of different kinds of fish: megrim (Lepidorhombus boscii), common sole (Solea vulgaris), striped mullet (Mullus barbatus), anglerfish (Lophius piscatorius), and black-bellied angler (Lophius budegassa), caught in the South Adriatic Sea (South Italy). The highest total mercury levels were found in anglerfish (0.61-2.22 mg/kg wet wt, mean 1:26±0.58), followed by black-bellied angler (0.22±1.62 mg/kg wet wt, 0.68±0.36), megrim (0.05±0.92 mg… 

Total mercury and methylmercury content in edible fish from the Mediterranean Sea.

The objective of this study was to determine the current levels of total mercury and methylmercury in the muscle tissues of different fish species caught in the Mediterranean Sea to ascertain whether

Total and methylmercury residues in tuna-fish from the Mediterranean sea

The estimated weekly intake was far above the established Provisional Tolerable Weekly Intake for both species, and mercury was present almost completely in the methylated form in albacore and bluefin-tuna.

Evaluation of mercury levels in Pangasius and Cod fillets traded in Sicily (Italy)

The results showed the presence of higher mercury levels in pangasius and cod fillets than in cod, underline the importance of monitoring on imported fish before marketing, to evaluate better the risk of mercury exposure through fish and seafood consumption and of selecting safer fishes for consumption by those groups more sensitive to the toxic effects of this metal.

Content of mercury and cadmium in fish (Thunnus alalunga) and cephalopods ( Eledone moschata ) from the south-eastern Mediterranean Sea

Of the flesh samples of albacore, 42.8% exceeded the proposed tolerance for cadmium for human consumption, whilst for horned octopus, the established limit was not exceeded in any sample.

Cadmium and mercury in cephalopod molluscs: Estimated weekly intake

Cadmium and mercury concentrations were measured in the flesh and hepatopancreas of different species of cephalopod molluscs in order to establish whether the concentrations exceeded the maximum levels fixed by the European Commission.

Survey of total mercury and methylmercury levels in edible fish from the Adriatic Sea

In all the different species, mercury was present almost completely in the methylated form, with mean percentages between 70 and 100%, and a high exposure was associated with the consumption of only skates, frost fish and angler fish, thought the Consumption of the other species resulted in a weekly intake slightly below the established provisional tolerable weekly intake.

Mercury in fish: Concentration vs . fish size and estimates of mercury intake

The results of linear regression analysis showed a significant relationship between mercury concentrations and fish size for all species, and dietary consumption of larger size specimens leads to an increase in the exposure level for consumers.

Mercury contamination in commercial fresh and salt water fish of the Zabol Chahnimeh reservoirs and the Gulf of Oman (Iran)

Generally, mercury levels in the analysed fish samples were higher than WHO, FDA and US-EPA legal limits.

Mercury, lead and cadmium content of fresh and canned fish collected from Austrian retail operations Zum Quecksilber-, Blei- und Cadmiumgehalt in Frisch- und Dosenfisch aus dem österreichischen Einzelhandel

Ninety-three samples of fresh and canned fish (edible part) collected from Lower Austria, Burgenland and from Viennese retail operations were analysed for mercury, lead and cadmium. The mercury


Fifty samples representing eight species of freshwater Fish (Oreochromis niloticus, Clarias lazera, Labeo niloticus, Bagrus bajad, Synodontis schall, Morymyrus niloticus, Lates niloticus and



Total mercury in muscle of benthic and pelagic fish from the South Adriatic Sea (Italy).

Correlations between total mercury concentration and specimen weight were evident in all examined species except for goldline and skates, while in goldline the mean content of total mercury was the lowest.

Relation Between Total Body Weight and Concentrations of Manganese, Iron, Copper, Zinc, and Mercury in White Muscle of Bluefish (Pomatomus saltatrix) and a Bathyl-Demersal Fish Antimora rostrata

Concentrations of mercury (Hg) increased significantly with size (P < 0.001) in white muscle of bluefish (Pomatomus saltatrix) and a bathyl-demersal fish Antimora rostrata but concentrations of

Mercury accumulation in relation to size and age of Atlantic herring (Clupea harengus harengus) from the southwestern Bay of Fundy, Canada

A bioenergetics-based pollutant accumulation model was used to describe total mercury accumulation for the commercially valuable Atlantic herring aged 3 to 5 years with the predicted values falling within one standard deviation of the measured annual body burdens.
