“…However, in horse mackerel liver no consistent patterns were recorded. Therefore, the seasonal variations of metals concentrations measured in our study could depend upon several factors such as growth and reproductive cycles and changes in water temperature (Ersoy and Ç elik 2009). These variations can also be reported to the water circulation along the coast and upwelling intensity.…”

In the current study, ten elements contents (Fe, Zn, Mn, Cu, Cr, Co, Ni, Cd, Pb and Hg) have been measured in muscle and liver of four pelagic fish species (Engraulis encrasicolus, Sardina pilchardus, Scomber japonicus and Trachurus trachurus) from the north-west African coast (South Atlantic Moroccan coast), collected during summer and autumn seasons (July and December 2013, respectively). Significant differences in metal contents were found between the different species (p \ 0.05). Metals levels were also much higher in liver than those recorded in muscle tissues. The concentrations of Fe, Zn, Cd, Co, Cu and Pb were significantly higher in mackerel liver (p \ 0.05).While, in muscle, anchovy presents a higher content of Mn, Cu, Cr, Ni and Pb. A high level of cadmium was recorded in liver of the different species which can be attributed to an anthropogenic source (phosphate industry) and to natural sources (upwelling activities). The main concentration of toxic elements (Cd, Pb and Hg) recorded in the four edible muscles of pelagic fish species, under study, were below the established values by the European Commission Regulations and show that their effect on the consumers health can be considered as negligible.

“…Risk assessment is one of the fastest methods to evaluate hazard impacts on human health and is also needed to determine the levels of treatment that will tend to solve the environmental problems occurring in daily life (Ersoya and Celik 2009). Health risks for the general population of the south coast of Sfax from the consumption of D. annularis were assessed by estimating the target hazard quotient (THQ).…”

Contamination of trace metals in fish is regarded as a major crisis globally, with a large share in many developing countries. On the south coast of Sfax (Tunisia), concentrations of seven trace metals, i.e., cadmium (Cd), copper (Cu), iron (Fe), lead (Pb), mercury (Hg), nickel (Ni) and zinc (Zn), were evaluated in Diplodus annularis. The sampling was conducted during December 2014. The Cd and Zn concentrations were higher than the FAO/WHO and WHO permissible limits in all tissues, while Fe and Pb concentrations were higher than the WHO permissible limits in the gills and/or liver. The levels of metal accumulation varied between tissues: liver [ gills [ muscle. The total target hazard quotient (THQ) through consumption of fish, calculated by adding the individual THQs, was above 1, indicating that there is significant potential health risk associated with the consumption of D. annularis. Therefore, intake of sparaillon for the general population is a matter of concern.

“…The season which the seafood samples were collected and analyzed for presence of heavy metals is another determinative factor in the concentration of toxic elements. It seems that different seasonal dependent conditions such as water temperature, dietary factors and growth and reproductive cycles are effective on heavy metal fluctuations [28][29][30][31] . The higher metal content in winter might be a result from considerable rainfall which washed down the wastes [28][29][30][31] .…”

Severe discharge of sewage and industrial effluents into the Persian Gulf causes the deposition of various types of heavy metals and especially lead, cadmium, arsenic and mercury in the muscles of marine animals. The present study was carried out to evaluate the concentration of lead, cadmium, arsenic and mercury in the fish (Scomberomorus commerson), shrimp (Fenneropenaeus indicus) and lobster (Panulirus homarus) samples from Persian Gulf. All of the samples were collected from the shopping centers in the Boushehr city. Weight and length of samples were measured and recorded. Concentrations of lead, cadmium, arsenic and mercury in fish, shrimp and lobster samples were analyzed using atomic absorption spectrophotometer. Average length and weight of collected samples were 46.9±2.68 cm and 642.237±52 g for fish, 18.88±1.67 cm and 45.779±4.51 g for shrimp and 22.3±2.13 cm and 203.098±20 g for lobster. Heavy metals concentrations in fish samples were 91.67±9.21 for lead, 49.00±4.77 for mercury, 60.37±7.07 for cadmium and 101.33±9.85 μg/g for arsenic. Lead, mercury, cadmium and arsenic concentration ranges were 64-93, 104-135, 18-34 and 211-265 μg/g in shrimp and 260-390, 71-130, 114-348 and 118-318 μg/g in lobster, respectively. ANOVA test showed significant statistically differences (P<0.05) between the type of seafoods and concentration of heavy metals. However, the levels of toxic elements were less than allowable concentrations but consumption of the contaminated seafoods with low levels of heavy metals may be harmful for human health. Keywords
