“…Bashir et al, (2013) reported lower concentrations of Cd as compared to our study with mean concentration of 0.058 µg/g and 0.027 µg/g for fish muscles collected from Kapar and Mersing coastal waters in Malaysia. Additionally, the Cd concentrations in the muscles of different marine fishes harvested from Masan Bay, Korea (0.02 μg/g to 0.05 μg/g, dry weight) (Kwon and Lee 2001) were lower than those reported in our study. Kalay et al, (1999) reported higher concentrations of Cd as compared to this study with mean concentrations ranged from 1.28-1.60 µg/g for marine fish samples collected from Mediterranean Sea in 1996.…”

The concentrations of manganese (Mn), copper (Cu), zinc (Zn), nickel (Ni), cobalt (Co), lead (Pb) and cadmium (Cd) in the muscles of grey mullet (Mugil cephalus) that were collected from Gaza fishing harbor and the surrounding areas were investigated in this study. Eight sampling locations were selected to conduct the study along the coast of Gaza. The samples were taken in September, November 2013 and March 2014. Heavy metals were identified and analyzed by Flame Atomic Absorption Spectrophotometer. The mean concentrations of heavy metals in soft tissues of fish were as follows: Mn:0.90 µg/g; Cu:13.15 µg/g; Zn:25.87 µg/g; Ni:1.10 µg/g; Co:0.68 µg/g; Pb:1.82 µg/g and Cd:0.27 µg/g, respectively. The highest concentrations of metals in fish tissues were found to be detected for zinc (13.56-40.43 µg/g) and the lowest were for cobalt (nd-2.93 µg/g) and cadmium (0.02-0.51 µg/g). The heavy metal concentrations in most fish samples were found to be below the acceptable limits proposed for fish by various international standards such as European Union (EU), World Health Organization (WHO), and Turkish guidelines (TFC). Therefore, it can be concluded that no risk on human health would be elevated at present from the consumption of fish collected from Gaza fishing harbor.

“…A deficiency of zinc is marked by retarded growth, loss of taste and hypogonadism, leading to decreased fertility. Zinc toxicity is rare but, concentrations in water, up to 40 mg/kg, may induce toxicity, characterised by symptoms of irritability, muscular stiffness and pain, loss of appetite and nausea (NAS-NRC, 1974 ) and Kwon and Lee (2001) have reported lower chromium concentration than the present study. Average boron contents of fish samples were ranged from 0.17-1.87 µg g Results obtained from the present study reveal that the concentrations of Ni, Co, Cr and Al are below well the permissible limits and suggesting that these metals are at safer level.…”

“…The speciation of heavy metals provides critically important information for evaluating toxicity and ecological risk to animals and human (Fan et al 2008;Kwon and Lee 2001). Different chemical species of heavy metals have different activity, toxicity, and mobilization (Cai et al 2011;Lu et al 2010;Zheng et al 2013).…”

A total of 271 sediments samples from the Zhalong Wetland were analyzed for concentration and distribution of Hg, Cd, As, Cu, Pb, Zn, Cr, and Zn; their speciation according to the modified European Community Bureau of Reference sequential extraction procedures and their ecological risk based on Lars Hakanson's potential ecological risk assessment and risk assessment code were made. The results can be summarized as the followings: (1) Concentrations of all metals measured were above soil background values of Songnen Plain, and their spatial distributions were distinctly different. The concentrations of metals (except Pb) were high in the east, followed by the north, and were relatively low in the core zone and south. The concentration of Pb was high in the north, south, and west, compared with low concentration in the core zone and east. (2) The dominant proportion of Pb, Zn, and Cr was in the residual fraction, suggesting that they were environmental stable. The concentrations of Cu and As in the reducible fraction, the concentration of Cd in the acidsoluble fraction, and the concentration of Hg in the oxidizable fraction were relatively high, indicating they had greater environmental effects. (3) The evaluation of the ecological risk showed that Cd, Hg, and As had relatively high ecological risk index, especially the ecological risk of Cd should be paid attention to. In general, the ecological risk of the heavy metals and metalloid by zone was experimental zone [ buffering zone [ ecological tourism zone [ core zone.
