“…THQ values greater than 1 indicate that a potential health risk may occur. Our results demonstrated that the THQ of individual metals did not pose a potential risk, but the total THQ exceeded the classification of no risk level (total THQ[1), as recommended by the USEPA (2000), suggesting direct health effects may be significant for the general population and especially for local inhabitants (Huang et al 2008;Krishna et al 2014;Li et al 2015). Thus, constant monitoring of both essential and non-essential metals remains very important to evaluate the risk for people consuming contaminated fish from the study area-and what can be done to lower this risk.…”

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.

“…If the THQ is >1, there is a risk to the health of the exposed population from consuming the product; if the THQ value is <1, there is no risk. In the current study, exposure to many pollutants (metals) was assessed; therefore, the total THQ or hazard risk (HI) was also calculated as the arithmetic sum of the individual metal THQ values, following the method of [26,27,31].

The bioaccumulation of heavy metals (Fe, Cu, Zn, Mn, Pb, Cd, Co, and Ni) were assessed in tissues (gills, liver, and muscles) of the thinlip mullet (Liza ramada) collected from three aquatic habitats varying in salinity in Egypt (freshwater, brackish, and offshore sites). In the freshwater site, metals accumulate in order of gills > liver > mussels with exception to Cu, Zn and Ni (liver > gills > mussels). In the brackish site, the order of metal accumulation for Fe, Cu, Zn, and Co were: liver > gills > mussels, and for Ni, Pb, and Mn were: gills > liver > mussels, while; Cd accumulated in order of mussels > gills > liver. In offshore site, Metals accumulates in order of: liver > gills > mussels except for Mn and Ni (gills > liver > mussels) and Cd (mussels > gills > liver).The overall metal concentrations for the three sites were ranked in the order of Fe > Mn > Zn > Cu > Pb > Cd > Co > Ni. There were significant differences between sites for Cu and Co, and between fish organs for Pb, Cd, Co, and Ni. Strong positive correlations were found between Fe and Zn (P<0.001), Fe and Pb (P<0.001), Fe and Mn (r= P<0.001), Mn and Ni (P<0.001), and Cd and Ni (r= P<0.01). Significant positive correlations (p<0.05) were observed between Zn with Co and Fe with Ni. Target hazard quotient (THQ) values for Pb, Cd, Co, and Ni were higher than 1 for the three sites, which suggests that adverse health effects might arise from the consumption of these fish. The estimated daily intake (EDI) values for Ni and Cd were higher than the recommended levels, indicating health effects; however, the values for rest of the metals were lower than the recommended EDI levels, suggesting that they are unlikely to pose a health risk.

“…Thus, accumulation occurs in the tissues of fish and can be transferred to higher trophic levels via food chain. Therefore, it is important to evaluate the concentration of toxic elements in fish, because it is representing a potential health risks to the fish organisms and to the higher trophic level organism like humans that potentially consume them (Li et al 2015;Vu et al 2017). Actually, numerous studies have been carried out on trace metals contamination of different species of edible fish (Prudente et al 1997;Kucuksezgin et al 2001;Lewis et al 2002;El Morhit et al 2009;Chahid et al 2014;Afandi et al 2015;Diop et al 2016).…”

Trace metal distribution in pelagic fish species from the north-west African coast (Morocco)

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.
