“…Arsenic in marine organisms exists in two forms: organic and inorganic (arsenobetaine, arsenocholine, and organoarsenicals) (Raknuzzaman et al, 2016). Inorganic arsenic is considered the most toxic form (Sharma et al, 2014).…”

Among all available species, fish are a powerful model for risk-benefit assessments to study the effects of contaminants on human health. Gilthead seabream (Sparus aurata, Linnaeus 1758) and european seabass (Dicentrarchus labrax, Linnaeus 1758) are two species of great economic importance, representing very large production volumes in the Mediterranean. The objective of this study is (1) to analyze the concentrations of Trace Elements (TE) between wild and cultured seabream and seabass specimens, (2) to compare the determined concentrations with other studies, and (3) to increase the data about the potential risks to human health. Our results point to significant intra- and interspecies-specific differences between wild and cultured fish for several trace elements. Several strong and moderate inter-elemental correlations in fish muscle were observed through correlation analysis. In our study, the mean levels of trace elements were still below the standard safety values for fish intended for human consumption. The same results were reached for all the parameters analyzed (international legal limits, estimated weekly intake, provisional tolerable weekly intake, target hazard quotient, target cancer risk), with trace element levels in fish below those that could pose a risk to human health. Consequently, these fish can be considered safe for human consumption. A better understanding of the levels of trace elements in fish would also better inform consumers about the potential risks of exposure to contaminants.

“…Rahman et al (2012) worked on concentrations of eight heavy metals (Pb, Cd, Ni, Cr, Cu, Zn, Mn, and As) in the muscles of ten species of fish collected from Bangshi river at Savar in Bangladesh and found their concentrations below the safe limit thus there was no indication of pollution. Raknuzzaman et al (2016) determined seven trace metal concentrations (Cr, Ni, Cu, Zn, As, Cd and Pb) in some commercial fishes and crustaceans collected from coastal areas of Bangladesh. Trace metals in fish samples were in the range of Cr (0.15 - 2.2), Ni (0.1 - 0.56), Cu (1.3 - 1.4), Zn (31 - 138), As (0.76 - 13), Cd (0.033 - 0.075), and Pb (0.07 - 0.63 mg/kg wet weight (ww), respectively.…”

Heavy metals are non-biodegradable substances which cause serious carcinogenic effects on animals and humans. As fish occupy top position of aquatic food chain, it is a major source of heavy metal contamination. The concentration of Cd, Cr, Pb, Mn, Fe, Cu, and Zn were 0. 0156 -0.1428, 0.163 -8.53, 0.0924 -0.4026, 9.38 -65.9382, 0.0473 -0.1981 and 0.1473 -1.8148 ppm respectively for the fish samples of Cox's Bazar region while 0.0191 -0.1386, 0.8445 -0.1743, 0.102 -0.4625, 0.102 -0.4675, 9.7269 -60.5267, 0.3108 -0.046 ppm for the fish samples of Saint Martin's region. Comparatively high concentrations of heavy metals were found to be accumulated in Mola (Amblypharyngodon mola), Rupchanda (Stromateus chinensis) and Chhuri (Trichiurus lepturus). The order of heavy metal concentrations were Fe > Zn > Cr > Cu > Mn > Cd. The concentration of heavy metals varied from species to species and most of the metals were not significantly correlated, even some metals showed negative correlation among them. Concentration of Fe in some fishes (Mola, Rupchanda and Chhuri) was found higher than WHO guideline values, while other metals exhibited the value below the WHO standard. The results of this study will assist in acquiring information about the level of toxic metals in these regions and to improve the coastal management in these areas in future.

“…Whether essential or non-essential, they become toxic beyond a certain threshold (Amiard et al, 1987). Since marine organisms are able to accumulate trace metals, some of them like fish are sometimes considered relatively good semi-quantitative bioindicators, reflecting the occurrence and bioavailability of contaminants in areas where they live (Raknuzzaman et al, 2016). However, trace metal concentrations in marine organisms result of a balance between their uptake and excretion processes (Gobert et al, 2017;Guven et al, 1999).…”

Concentrations of 6 trace metals (Ag, Cd, Cu, Ni, Pb, Zn) in the muscle of 2 sharks (Galeus melastomus and Scyliorhinus canicula), 4 teleosts (Helicolenus dactylopterus, Lepidorhombus boscii, Micromesistius poutassou and Phycis blennoides) and 1 crustacean (Nephrops norvegicus) were compared between the Bay of Biscay (Atlantic Ocean) and the Gulf of Lions (Mediterranean Sea). Although average concentrations and the trace element pollution index were generally higher in the Gulf of Lions, significant differences between the two ecosystems were only found for Zn for Helicolenus dactylopterus, and for Ag and Cu for the crustacean N. norvegicus. Moreover, some relationships between trophic level or size and metal concentrations were found for these two species. The absence of clear pattern may result from the blurring effect of contamination and excretion that may act differentially for all species and all elements. Highlights► Low concentrations of trace metals in the muscle tissue for all studied marine species ► Absence of clear patterns for all studied species and elements ► Metal concentrations were mainly higher in the Gulf of Lions than in the Bay of Biscay.
