“…In most cases, lower values have also been reported for Hg content in megrim muscle; thus, specimens obtained in the Portuguese coast showed 0.33 ± 0.24 (Afonso et al ., ) and 0.36 ± 0.18 (Cardoso et al ., ) mg kg −1 muscle levels, while megrim from the Adriatic Sea led to slightly lower levels than in the present study (0.68 ± 0.21 mg kg −1 muscle; Storelli et al ., ). Concerning Pb detection, previous research accounts for lower values than in the actual study, too; these reports take into account specimens from the Portuguese (0.033 ± 0.008 mg kg −1 muscle; Afonso et al ., ) and Adriatic (0.08 ± 0.04 mg kg −1 muscle; Storelli et al ., ) coasts .…”

“…Different studies account for As assessment, being all values reported lower than the current ones; such reports account for specimens from the Portuguese coast (11.6 ± 4.74 mg kg −1 muscle; Anacleto et al ., ), and from specimens acquired in Galician (North‐West Spain) (42.5 ± 1.3 mg kg −1 dry muscle; Lavilla et al ., ) and Basque (North Spain) (28.45 ± 17.71 mg kg −1 dry weight; Muñoz et al ., ) harbours. In most cases, lower values have also been reported for Hg content in megrim muscle; thus, specimens obtained in the Portuguese coast showed 0.33 ± 0.24 (Afonso et al ., ) and 0.36 ± 0.18 (Cardoso et al ., ) mg kg −1 muscle levels, while megrim from the Adriatic Sea led to slightly lower levels than in the present study (0.68 ± 0.21 mg kg −1 muscle; Storelli et al ., ).

“…This accounts for optimisation of on-board storage conditions (Pastoriza et al, 2008), gelatine preparation from skin (G omez-Guill en et al, 2002), employment of new strategies for quality enhancement (Miranda et al, 2016) and assessment of essential microelements content (Afonso et al, 2013;Cardoso et al, 2015). As being a flat species living in the sea bottom, megrim has also attracted a great attention for its content in toxic elements, such levels being taken as indicators of water pollution and contamination (Lavilla et al, 2008;Storelli et al, 2013).…”

Summary The chemical composition of the different edible locations (central and edge muscles) of a flat fish (megrim, Lepidorhombus whiffiagonis) was comparatively analysed at both body sides. Higher moisture and lower lipid contents were obtained in central muscles than in edge ones. Edge sites showed higher triacylglycerols and sterols contents and lower mean phospholipids values than central muscles. A higher α‐tocopherol presence was observed in the lipid fraction of central muscles than in the edge ones. For both fish sides, fatty acid (FA) analysis showed lower monounsaturated FA and higher polyunsaturated FA contents and ω3/ω6 ratios in central muscles. Presence of essential elements (Co, Cu, Mn, Se, Zn) did not provide differences among sites considered. Concerning toxic elements, As content showed greater levels in central muscles than in their corresponding edge sites for both fish sides, upper zones showed higher mean scores in As, Cd, Cr, Hg, Ni, Pb and V.

“…Compared with other studies, the Pb levels of 0.13 ± 0.12 mg kg À1 in the M. curema obtained in this study were lower than the 0.25 ± 0.05 mg kg À1 reported for Mugil brasilienses from Baia de Todos os Santos, BA, Brazil (Santos et al 2013) and the 0.17 ± 0.09 mg kg À1 in mullet marketed in Palestine (Elnabris et al 2013). A study by Silva et al (2016) found values ranging from 0.019 to 0.022 mg kg À1 in sea bream (Archosargus rhomboidalis) and snapper (L. synagris) marketed in Salvador, BA, Brazil, while in the Mediterranean, Storelli et al (2013) observed Pb concentrations ranging from 0.08 to 0.12 mg kg À1 , considered safe for consumption.…”

Arsenic, cadmium, lead, and mercury in fish is the result of longterm biomagnification in the food chain and is of public concern, due to the toxicity they engender. The objective of this research was to determine the concentrations of arsenic, cadmium, lead, and mercury in 13 species of marine fish broadly commercialized in Aracaju, SE, Brazil and to evaluate the risks of fish consumption associated with these trace elements, using the Target Hazard Quotient (THQ). As, Cd, and Pb levels were measured with inductively coupled plasma mass spectrometry (ICP-MS), and mercury was analyzed via cold vapor atomic absorption spectrometry. The results indicate a large variability in concentrations for arsenic (0.07-2.03 mg kg -1 ) and mercury (0.01-1.44 mg kg -1 ), associated with the animal dietary category. Cadmium (0.04-0.19 mg kg -1 ) and lead (<0.01-0.45 mg kg -1 ), on the other hand showed a mild variability. None of the evaluated specimens had As, Cd, and Pb THQ values higher than 1. The THQ values for mercury were higher but indicated no consumption risk, except for amberjack, and snook fish. Overall THQ indicates lower risk of consumption in fish that are at the base of the food chain, than in those that are top predators.

“…The detrimental effects of individual metals and PAHs on fi sh have been substantiated by a number of studies [4][5][6]. But still there are gaps in our knowledge on the combined toxicity of these pollutants [7], although co-contamination of metals and PAHs has been constantly found in the aquatic environment [8][9][10].…”

To evaluate potential interactive effects of metals and polycyclic aromatic hydrocarbons (PAHs) on biomarker responses, groups of the freshwater fi sh crucian carp (Carassius auratus) were exposed to single and binary combinations of copper (Cu) (0.01-0.16 mg L-1) with fl uorene (Fl) or fl uoranthene (Fluo) (2-10 mg kg -1 ) for 96 h. Dose-dependent increases in the activities of phases I and II metabolic enzymes [7-ethoxyresorufi n O-deethylase (EROD) and glutathione-S-transferase (GST), respectively] were observed in fi sh liver exposed to Fl and Fluo, but these enzyme activities did not differ signifi cantly from the controls when co-treated with higher concentrations of Cu, suggesting an inhibiting interaction on the metabolic enzymes. Although Cu did not alter catalase (CAT) activity, CAT activity was decreased in fi sh liver exposed to the two PAHs alone or in combination with Cu. Although metallothionein (MT) content in gills was signifi cantly increased following exposure to Cu alone or in combination with Fl and Fluo, the induction folds of MT decreased under co-exposure. Co-exposures to these chemicals invoked complex biomarker responses in fi sh liver and gills. These results highlight the need for careful consideration of the interactive effects of multiple environmental stressors on fi sh.
