“…Similar results were found by numerous authors [29,30]. Tese results could be related to the role of this functional organ as a site of accumulation, detoxifcation, and distribution [40,41]. Furthermore, this fnding could be explained by the fact that the gills constitute provisional target organs for toxic substances accumulation before being transferred afterward to the digestive organs such as the liver, kidneys, and intestine then the metals reach the bloodstream where they will bind to the hemoglobin then be transported to target tissues.…”

Due to their toxicity, long persistence, bioaccumulative nature, and biomagnification in the food chain, heavy metals pose a serious hazard. The aim of this study was to evaluate the health risks associated with the consumption of Sardina pilchardus (Walbaum, 1792) and to study the spatiotemporal dynamics of four potentially toxic metallic elements. Three hundred and sixty specimens of sardine were collected between December 2020 and October 2021 at three Mediterranean coast sites, Beni-Ensar, Ras el Ma, and El-Houceima, in the northeast region of Morocco. The toxic metallic elements were evaluated by assessing the contamination level of cadmium (Cd), mercury (Hg), lead (Pb), and arsenic (As) in the muscle, liver, and gills of sardine from the Mediterranean Moroccan coast. The results showed a significant effect of the study area, organ, and season ( p > 0.05 ) on Moroccan Mediterranean sardine heavy metal contamination levels. Regardless the location and season, the liver presents the higher concentration of the studied metals ( p < 0.05 ). The highest heavy metal concentrations of Cd (0.408 μg·g−1 wet weight (ww)), Hg (0.044 μg·g−1 ww), and As (6.74 μg·g−1 ww) were found in winter while the concentration of Pb was the highest in autumn (0.056 μg·g−1 ww). Furthermore, the lowest contamination of metal levels was found in the spring. El-Houceima region contains the highest values for Hg (0.093 μg·g−1 ww), Pb (0.018 μg·g−1 ww), and As (7.73 μg·g−1 ww). However, the highest values for Cd (0.172 μg·g−1 ww) were recorded in Beni-Ensar. Regarding the assessment of possible risks to human health, the results showed that the indices are below the established safety values in the case of estimated weekly intake, and target hazard quotient (THQ). In contrast, the carcinogenic risk index and total THQ were above the threshold limits and thus represented a potential carcinogenic risk to human health.

“…Although this species has been reported as having mechanisms to help it deal with As and other contaminants (i.e. metallothioneins) (Hauser-Davis et al, 2021), our results are to be expected given the antioxidant role of the aforementioned enzymes (Winston and Di Giulio, 1991). Notably, organic contaminants were negatively associated with Se_GPx, which aligns with earlier observations using the same species also collected in the North Atlantic (Alves et al, 2016).…”

“…Pb, Cd, and Ni concentration in R. acutus and S. lewini from Binuangeun show a lower trend than the previous result on Ong and Gang [21] from Kuala Terengganu, Malaysia, Boldrocchi et al [27] from Djibouti, Indian Ocean areas, and Adel et al [20] from the Persian Gulf. This study's Cd, Ni, and Pb concentrations were lower than Hauser-Davis et al [31] on blue sharks (Prionace glauca) from the Western North Atlantic Ocean. The concentration of Cd and Pb in S. lewini reported by Mohammed and Mohammed [22] from Trinidad and Tobago shows a higher concentration in all muscles (hypaxial muscle, epaxial muscle, and dorsal fin) compared to this study.…”

“…Unfortunately, there are no studies of titanium accumulation by sharks in the study area. The concentration of Ti in this study was shown to be lower compared to the study reported by Hauser-Davis et al [31] on P. glauca from the Western North Atlantic Ocean and Ju et al [34] on megamouth sharks (Megachasma pelagios) from Taiwan. However, higher than a study reported by Bouchoucha et al [35] from the Western Mediterranean Sea on commercial fishes.…”

Metals accumulation in threatened sharks’ meat represents a global health issue. The objective of the current study was to measure the concentration of six metals (Li, Ti, Ni, Cd, As, and Pb) using ICP-MS in threatened sharks’ meat of Rhizoprionodon acutus, Squalus hemipinnis, and Sphyrna lewini from Binuangeun Fish Auction in Lebak, Banten, Indonesia. The results showed that the concentration of Ni, Li, Cd, and Pb was below the acceptable levels for food sources for human consumption, except for As concentration (more than 30 fold higher). This study showed high levels of Ti concentration in all threatened sharks' meat. Overall, this study shows that an accumulation of Ti in sharks' meat should be considered a risk to the health of seafood consumers.
