“…This is due to the higher availability of Hg at the water-sediment interface, caused by the continuous production of methylmercury in this system (Bratki c et al 2017). Nonetheless, after Farrugia et al (2015) a reduction in mercury toxicity is attained when fish present higher concentrations of selenium.…”

“…Fish meat is rich in essential amino acids, vitamins, micro-and macroelements, and ômega-3 long-chain polyunsaturated fatty acids such as docosahexaenoic acid and eicosapentaenoic acid, and is also low in cholesterol (Guil-Guerrero et al 2011). These characteristics confer on fish meat the advantage of qualifying as one of the more healthful foods (Storelli 2008;Afonso et al 2013;Farrugia et al 2015); its consumption is beneficial for neurological growth and development, and it reduces the risk of stroke disease and the incidence of cardiovascular diseases, while also enhancing the human immune response (He 2009;Pohlenz and Gatlin 2014). In contrast to the dietary advantages of fish, however, the potential risk of exposure to chemical contaminants (and their derivatives) contained in fish must also be considered, when assessing the influence of this food on human health (Bosch et al 2016).…”

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.

“…Thornback ray skin's gelatin hydrolysate using proteases derived from B. subtilis and B. amyloliquefaciens has been previously described as a potential source of bioactive peptides (Lassoued et al, 2015a). The muscle of thornback ray has been the focus of study for mercury and trace element analysis due to its high amount of fat and the increasing safety concern in society ( Farrugia et al, 2015). However, recent studies emphasise the positive benefits of this type of fish as a source of good quality proteins based on the balance of omega-3 fatty acid benefits (Afonso et al, 2013).…”

Summary Angiotensin I‐converting enzyme (ACE) inhibitory peptides have been searched in thornback ray (Raja clavata) muscle hydrolysed with Bacillus subtilis A26 proteases until a hydrolysis degree of 18.35%. The hydrolysate showed an IC50 of 0.83 mg mL−1. To identify peptides responsible for this activity, the extract was eluted through size‐exclusion chromatography and fractions collected. The highest ACE inhibitory activity was found for fractions F2 and F3 which had IC50 of 0.42 and 0.51 mg mL−1, respectively. These fractions were analysed by nano‐liquid chromatography coupled to tandem mass spectrometry (nLC‐MS/MS). A total of 131 and 108 peptide sequences mainly derived from actin, myosin heavy chain and procollagen alpha 1 chain proteins were identified in fractions F2 and F3, respectively. FQPSF and LKYPI showed the best results with an IC50 of 12.56 and 27.07 μM, respectively. These results prove the potential of thornback ray muscle hydrolysate as a source of ACE inhibitory peptides.

“…Concerning batoids, the published data are scarce or even non-existent, as in the case of torpedinids. The few studies on skates seem to indicate that consumption of these species provide far more Se than Hg to the consumer [ 15 , 57 , 68 ]. This suggestion is in an agreement with the findings of the current study, which shows a healthy profile of these species and provides a clear example of integration between Se-specific nutritional benefits and the potential Hg-exposure risks.…”

This study measures total mercury (THg), methylmercury (MeHg) and selenium (Se) concentrations in elasmobranch fish from an Italian market with the aim of evaluating the risk-benefit associated with their consumption, using estimated weekly intake (EWI), permissible safety level (MeHgPSL), selenium health benefit value (HBVSe) and monthly consumption rate limit (CRmm) for each species. THg and Se were analysed by atomic absorption spectrometry, while MeHg was determined by HrGc/Ms. THg and MeHg concentrations ranged from 0.61 to 1.25 μg g−1 w.w. and from 0.57 to 0.97 μg g−1 w.w., respectively, whereas Se levels were 0.49–0.65 μg g−1 w.w. In most samples European Community limits for THg were surpassed, while for MeHg none of the fish had levels above the limit adopted by FAO/WHO. EWIs for THg and MeHg in many cases were above the provisional tolerable weekly intakes (PTWIs). MeHgPSL estimate showed that fish should contain approximately 50% of the concentration measured to avoid exceeding the PTWI. Nevertheless, the HBVSe index indicated that solely skates were safe for human consumption (HBVSe = 3.57–6.22). Our results highlight the importance of a constant monitoring of THg and MeHg level in fish, especially in apex predators, to avoid the risk of overexposure for consumers.
