Total mercury concentrations were determined in different fish size classes of commercial importance such as, conger eel (Conger conger), starry ray (Raja asterias), forkbeard (Phycis blennoides), frostfish (Lepidopus caudatus), striped mullet (Mullus barbatus), red gurnard (Aspitrigla cuculus) and yellow gurnard (Trigla lucerna) in order to evaluate variations in consumer exposure to mercury as a function of fish consumption of a spectrum of different sizes. The highest mean levels of total… 
Assessment of mercury in muscle of fish from Cartagena Bay, a tropical estuary at the north of Colombia
Results suggest fish from the bay pose a low health threat for humans in terms of Hg exposure, vulnerable groups such as pregnant women, should avoid eating large size carnivorous species, and knowledge about species with low Hg content should be widespread within fishing communities.
REVIEW AND ANALYSIS OF MERCURY LEVELS IN BLUE MARLIN (Makaira nigricans, Lacepède 1802) AND SWORDFISH (Xiphias gladius, Linnaeus 1758)
The present study summarized the information about mercury levels in billfishes available in the literature, with emphasis on swordfish and blue marlin and made an analysis of data from several studies using the multivariate technique Agglomerative Hierarchical Cluster (AHC).
Total mercury content, weight and length relationship in swordfish (Xiphias gladius) in Sri Lanka
Hg concentration of swordfish showed a significant positive relationship (P value < 0.05) with the fish length and weight, which leads to an increase in the exposure level for consumers.
Organotropism of methylmercury in fish of the southeastern of Brazil.
Toxic metals (Hg, Cd, and Pb) in fishery products imported into Italy: suitability for human consumption.
The samples analyzed were considered safe to eat with regard to the metal concentrations found and the allowable intakes based on legislation, Nevertheless, the consumption of some species may be of significant importance for consumer health.
Mercury and selenium levels in 19 species of saltwater fish from New Jersey as a function of species, size, and season.
Toxic metals (Hg, Pb, and Cd) in commercially important demersal fish from Mediterranean sea: contamination levels and dietary exposure assessment.
Fish size-related changes in Hg concentrations determined high THQ and EWI values relatively to larger size fish consumption of these species, except for red mullet, suggesting potential health human risk.


Fish for human consumption: risk of contamination by mercury
Correlations between total mercury concentration and specimen weight were evident in all the species examined, and according to current regulations, 62.5% of anglerfish and 23% of black-bellied angler samples showed concentrations exceeding the peak value of 1 mg/kg, while only 25% of samples of megrim (Lepidorhombus boscii), and 8.3% of striped mullet (Mullus barbatus), exceeded the peakvalue fixed at 0.
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.
Heavy metal distribution in different fish species from the Mauritania coast.
Total mercury levels in muscle tissue of swordfish (Xiphias gladius) and bluefin tuna (Thunnus thynnus) from the Mediterranean Sea (Italy).
For bluefin tuna the total mercury level variability observed, due to size, suggests that there should be greater regulatory control by the authorities.
Mercury contamination of fish and exposures of an indigenous community in Pará state, Brazil.
Although the levels of Hg in fish consumed by the Sai Cinza community are below the Brazilian limit value for consumption, the high rates and amounts ofFish consumed by this population are relevant to evaluating risks of mercury contamination for communities with limited food resources.
Concentrations of heavy metals associated with urban runoff in fish living in stormwater treatment ponds
Redear sunfish (Lepomis microlophus), largemouth bass (Micropterus salmoides), and bluegill sunfish (Lepomis macrochirus) were collected from stormwater ponds and natural lakes and ponds (controls)
Distribution of trace elements in the tissues of benthic and pelagic fish from the Kerguelen Islands.
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.
Exposure assessment for heavy metal ingestion from a sport fish in Puerto Rico: estimating risk for local fishermen.
The possibility that in certain localities and cultures sport or subsistence fishermen may consume fish at levels substantially above 200 g/d should be investigated in performing risk assessments, particularly outside the continental United States.
