“…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).…”

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 rate of accumulation is variable depending on aquatic organisms and heavy metals (Heath, 1987). As fish have an important role in the human diet, numerous researches have been carried out on the accumulation of heavy metals in different species of fish (Kucuksezgin et al, 2001;Lewis et al, 2002;Prudente et al, 1997). Discharging heavy metals into the marine environments is one of greatest concerns worldwide.…”

The present study has been carried out to evaluate the concentration of copper (Cu) and vanadium (V) elements in the muscle, skin, and gill tissues of Tylosurus crocodilus (Belonidae), an edible fish, in the Bahregan region which is located in the northern part of the Persian Gulf. For this purpose, 18 fish samples in three different length groups (small, medium, and large) were randomly collected in Bahregan region. Tissues were separated and concentration of the heavy metals was determined by atomic absorption. The results showed that mean concentration of Cu and V were 0.2851 ± 0.10036 and 1.1368 ± 0.12405, 0.1117 ± 0.02322 and 2.5091 ± 1.14201 and 0.1803 ± 0.03204 and 3.3133 ± 1.05995 µg g -1 dry weight, in skin, muscle and gill tissues, respectively. Also, the results revealed a significant positive correlation between the standard length and Cu concentration in the muscle and gill tissues (P ≤ 0.05), as well as between the standard length and V concentration in all the tissues (P ≤ 0.05). The results indicated that the concentration of V was higher than the World Health Organization (WHO) standard but the concentration of Cu was lower. It is therefore highly recommended that usage of this carnivore species in the studied area is limited because of the high accumulation of V in its muscle tissue.

“…Concentrations of organic contaminants in fishes may vary widely in relation to feeding habits, the nature of the habitat and environmental factors such as coastal marine pollution (Loizeau, 2001;Lewis et al, 2002;Naso et al, 2005). In European waters, PCBs concentration in tissues from juvenile sea bass varied from 130 ng g À1 (lw) in Gironde to 5380 ng g À1 (lw) in Scheldt (Schnitzler et al, 2011), with unknown consequences for their thyroid function (Fig.…”

Environmental factors affecting thyroid function of wild sea bass (Dicentrarchus labrax) from European coasts

a b s t r a c tThyroid functional status of wild fish in relation with the contamination of their environment deserves further investigation. We here applied a multi-level approach of thyroid function assessment in 87 wild sea bass collected near several estuaries: namely the Scheldt, the Seine, the Loire, the Charente and the Gironde. Thyroxine (T 4 ) and triiodothyronine (T 3 ) concentrations in muscle were analyzed by radioimmunoassay. The activity of hepatic enzymes involved in extrathyroidal pathways of thyroid hormone metabolism, viz. deiodination, glucuronidation and sulfatation were analyzed. Last, follicle diameter and epithelial cell heights were measured. We observed changes that are predicted to lead to an increased conversion of T 4 -T 3 and lowered thyroid hormone excretion. The changes in the metabolic pathways of thyroid hormones can be interpreted as a pathway to maintain thyroid hormone homeostasis. From all compounds tested, the higher chlorinated PCBs seemed to be the most implicated in this perturbation.
