“…Only a small hand full of surveys have been conducted for this region of the EMS (Duran et al., 2014; Elnabris, 2013; Micheline et al., 2019). However, it has been reported that coastal contamination is higher in some areas of the eastern basin compared to the central and western basin (Copat et al., 2015). Our study finds the contrary, with samples from this study showing lower concentrations with means below 0.1 mg/kg (Table 2).…”

“…The FAO has listed consumption of fish in Israel as the third‐highest among countries bordering the Mediterranean Sea, at a consumption rate of 50 g capita −1 day −1 (Copat et al., 2015). However, according to the Ministry of Agriculture, while in 2017 Israel supplied a total of 161,000 tons of fish to the public, only 1% of the supply originated from local fisheries, equating to 2.7 kg year −1 individual −1 (Herskovich, 2018).…”

“…The revised guidelines of the IVS have set ML for Cd, Hg, and Pb in seafood, yet exclude As (IVS, 2020). This comes as a concern since marine organisms have been well documented to accumulate high concentrations of As in their tissues (Azizur Rahman et al., 2012; Copat et al., 2015; Ferrante et al., 2019), with seafood recognized to contain higher levels compared to other consumed foodstuffs (Brandon et al., 2014; Francesconi & Edmonds, 1996; Miklavčič et al., 2013; Traina et al., 2019). With lacking guidelines on As, whether the levels seen in this study are indeed safe for human consumption remains open for debate.…”

Seafood is capable of bioaccumulating heavy metals (HM), making it a potentially major dietary source of HM for humans. Presently, little data exists on seafood from the eastern‐most boundary of the Mediterranean Sea. This study aims to provide exposure insight of the Israeli population to HM through the consumption of locally caught seafood by assessing the levels of arsenic, mercury, cadmium, and lead in raw tissues of seafood. A wide survey of local fisheries was conducted providing 296 samples from 11 different species, including seven fish, two crustacean, and two cephalopod species. Total arsenic, cadmium, and lead were analyzed by graphite‐furnace atomic absorption. Total mercury was measured by cold‐vapor mercury analyzer. Arsenic speciation was performed by anion chromatography‐inductively coupled plasma sector field mass spectrometry. Results suggested that the total arsenic concentrations were significantly higher in crustaceans and cephalopods than fish. Arsenic speciation revealed two samples that exceed 1 mg/kg of inorganic arsenic, whereas methylated arsenic was below the detection limit. Elevated mercury levels were detected in the commercial benthic species Mullus barbatus (red mullet), cadmium was detected in one‐third of the samples, and lead detected in eight samples. Comparing the results to health guidelines, 99.4% of seafood tested in this study abide with acceptable levels of heavy metals in seafood, as defined by both Israeli and European Union guidelines.

“…Cadmium (Cd), one of the most toxic heavy metals, is widely distributed in the marine environment as a result of natural and anthropogenic activities (Copat et al 2015). Cd has already been detected at high levels in Mediterranean marine environment about 0.02 mg/L (Gharred et al 2015b) and can cause adverse effects on organisms inhabiting these ecosystems (Dermeche et al 2012).…”

Multiple pollutions by trace metals and pharmaceuticals have become one of the most important problems in marine coastal areas because of its excessive toxicity on organisms living in this area. This study aimed to assess the individual and mixture toxicity of Cu, Cd, and oxytetracycline frequently existing in the contaminated marine areas and the embryo-larval development of the sea urchin Paracentrotus lividus. The individual contamination of the spermatozoid for 1 h with the increasing concentrations of Cd, Cu, and OTC decreases the fertility rate and increases larvae anomalies in the order Cu > Cd > OTC. Moreover, the normal larva frequency and the length of spicules were more sensitive than the fertilization rate and normal gastrula frequency endpoints. The mixture toxicity assessed by multiple experimental designs showed clearly that concentrations of Cd, Cu, and OTC superior to 338 μg/L, 0.56 μg/L, and 0.83 mg/L, respectively, cause significant larva malformations.

“…In addition, albacore tuna is a high-performance fish with very high metabolitic rates, which contributes to the enhanced bioaccumulation of such metals [ 16 ]. Mercury, Cd, and Pb as non-essential elements can be very harmful even at low concentrations, occupying top positions in the lists of toxicants and recognized for their toxicity towards most organisms [ 17 , 18 ], particularly fish and other seafood [ 19 , 20 ]. Their effects on human health were always of great interest.…”

Aegean Sea albacore (T. alalunga), fresh or processed, is marketed locally in Greece or exported, mainly to Japan, Italy, Spain, and France. To provide information for consumers and biomonitoring programs and assess the potential human health risks, concentrations of mercury (Hg), cadmium (Cd) and lead (Pb) were determined in albacore edible muscle samples from two fishing grounds of the Aegean Sea, Greece via graphite furnace atomic absorption spectrometry (GF-AAS). Of the 82 individuals, 28 contained Cd and three contained Pb above the permissible limits set by the European Union (0.1 mg kg−1 wet wt and 0.3 mg kg−1 wet wt, respectively). None of the samples contained mercury above the limit (1.0 mg kg−1 wet wt). Potential health risks to human via dietary intake of albacore were estimated by the total target hazard quotients (TTHQs), which indicated that the consumers could acquire health problems due to consumption of Aegean Sea albacore. Thus consequently, concentrations of toxic heavy metals in albacore, especially mercury, must be monitored regularly and comprehensively with respect to consumer health.
