“…Moreover, such accumulation is often influenced by different environmental factors and the feeding habit, habitat, age, sex and body weight of fish (Authman, 2008). Several studies have indicated tissue-dependent bioaccumulation pattern of heavy metals as observed in the present study (El-Moselhy et al, 2014;Malik et al, 2014). Relative rates of metal binding and release determine metal accumulation in various tissues.…”

-Fish are exposed to different heavy metals that may induce numerous physiological changes. In the present study, we examined the redox state in response to a severe stress resulting from two heavy metals (Zinc and Lead) contamination in carp Cirrhinus cirrhosus. Fish were exposed to 1/10th of LC50 of the respective metals [zinc chloride (2.72 mg/L) and lead acetate (2.53 mg/L)] for 30 days and allowed to recover for another 30 days without any metal exposure. Concentration of metals, different enzymatic and non-enzymatic antioxidant agents and expression levels of heat shock protein (HSP) 70 and 90 were measured in the liver and the kidney of fish. The lipid peroxide levels in fish tissues gradually increased with duration of treatment for both metals. After 15 days of treatment, glutathione (GSH) levels had increased, but decreased as the treatment continued for 30 days and returned to basal levels after a 30-day recovery period. Activities of all the anti-oxidant enzymes, except glutathione peroxidase, in stressed fish were significantly increased compared to those in the control at 15 days and continued till the 30th day of treatment, showing a tendency to return to basal levels after the recovery period. Expression levels of HSP70 and HSP90 gradually increased after zinc and lead treatment, respectively. The expression of HSP was higher in the liver. The results suggest that different heavy metals may have differential effects on the redox state and induction of oxidative stress in carp, in vivo.

“…In the last years, the health benefits related with seafood consumption have been extensively publicized (Mendil et al, 2010). The world consumption of fish has increased simultaneously with the growing concern of their nutritional and therapeutic benefits (El-Moselhy et al, 2014). In addition to its important source of protein, fish typically have rich contents of essential minerals, vitamins and unsaturated fatty acids (Medeiros et al, 2012).…”

“…On the other hand in polluted marine habitats the heavy metal levels in fish muscles may exceed the permissible limits for human consumption and refer to severe health risk (El-Moselhy et al, 2014). Legal thresholds are not available for essential elements in European Commission Regulation (EC).…”

Concentrations of heavy metals Cd, Fe, Pb, Cu, Zn, Ni, Co, Cr and Mn in muscles, liver, kidney and gills of marine and native commercial fish of Chacunda gizzard shad Anodontostoma chacunda collected from Karachi fish harbour were determined to conduct a health risk assessment for people by the Atomic Absorption Spectrophotometer. The obtained results were expressed mg/kg dry weight. Results showed that Fe and Zn concentrations were the most abundant among all tissues whereas Cd and Pb levels were the lowest. The data obtained in this study were compared with the international maximum permissible values. The estimated values of all metals in muscles of fish in this study were below the permissible limits. Generally, risk values for the measured metals do not pose unacceptable risks at mean ingestion rate for edible tissues. It can be concluded that the heavy metal levels in edible parts of A. chacunda have no hazards for consumers.
