“…We observed that the essential metals showed the same order of magnitude, however, only the toxic elements presented different order depending on fish environment. In comparison with data reported for pelagic fish from other locations, the observed amount of sequences are different from that indicated by Copat et al (2013) [ Cd). From these observations, we have noted that cadmium element is the less accumulated metal, at the opposition of our results, which show a large accumulation of cadmium especially in the liver.…”

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.

“…The analyzed swordfish samples represent a good nutritional source of essential trace elements. Thus, combining the detection of contaminants concentrations in food and the estimated consumption limits is of great relevance in view of assessing the balance between benefits and risks (Copat et al, 2013).…”

“…Heavy metals are stable, persistent, nonbiodegradable, and toxic contaminants of aquatic environments, and they can accumulate in organisms and food chains, therefore potentially threatening the health of aquatic organisms (Wu et al, 2013a,b) and human beings (Papagiannis et al, 2004). Heavy metal contaminations caused by industrialization, urbanization, and agricultural activities are increasing in aquatic environments, and it has become a serious issue worldwide (Tarras et al, 2001;Cheng, 2003;Malik et al, 2010), Many researchers have made efforts to determine heavy metal concentrations in aquatic environments and aquatic organisms, and to investigate the potential health risk of heavy metals to consumers caused by consumption of contaminated seafood (Copat et al, 2013;Li et al, 2013;Wei et al, 2014). Owing to the effects of bioaccumulation and biomagnification, some heavy metals with low concentrations could rise to hazardous levels through food chains in aquatic organisms (Castro and Mendez, 2008;Qiu et al, 2011).…”

“…The target hazard quotient (THQ) is a quantitative method of investigating the potential health risk caused by consumption of contaminated foodstuffs (US EPA, 2000), and it is used widely to evaluate the health risk of heavy metals to human beings (Yang et al, 2011;Copat et al, 2013;Fu et al, 2013).…”

a b s t r a c tTo investigate the pollution level and evaluate the potential health risks of heavy metals, the concentrations of chromium (Cr), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), selenium (Se), molybdenum (Mo), cadmium (Cd), antimony (Sb), and lead (Pb) were determined by inductively coupled plasma-mass spectrometry (ICP-MS) in 198 clams (Mactra veneriformis) collected from 11 sites of the Bohai Bay. The results showed that heavy metal concentrations in the clams were different at different sites (p < 0.05). Mn was dominant with a percentage of 22.08-77.03% in heavy metals, followed by Zn with 12.66-57.11%, and the concentration of Pb was the lowest with 0.45-1.04%. The potential health risk to consumers was evaluated by the target hazard quotient (THQ) and the maximum daily consumption rate (CR max ). The results indicated that the THQs of Co were the highest with the values of 1.125, 1.665, and 1.144 at three sections; the values of other individual metals were <1, which indicated that consumption of clams from the study areas caused health risks due to Co. Moreover, the CR max values also indicated the potential health risk caused by Co in clams consumed in this area. Pearson correlation analysis and principal component analysis (PCA) indicated that there were significantly positive or negative correlations between the heavy metals (p < 0.05), and the studied metals were divided into four groups. The results indicated that the concentrations of heavy metals in clams were affected not only by pollution sources but also by the characteristics of clams that could absorb selectively and accumulate special metals. This study offers important information on the pollution levels of heavy metals in clams and warns consumers of the health risks associated with the consumption of clams in the area.
