“…The most polluted part of River Nile is the two branches, Damietta and Rosetta (NAWQAM, 2003). Heavy metals pollution in fish has become a worldwide concern, not only because of the threat to fish, but also the health risks associated with consumption (Lee et al, 2011).…”

The present study carried out to clarify the impact of heavy metals (Fe, Zn, Cu, Mn and Cd) pollution of Rosetta Branch on the antioxidant defence system activities and lipid peroxidation indicator MDA levels in O. niloticus tissues (liver and white muscles) collected from three stations from Rosetta Branch of River Nile in summer 2014 and winter 2015. Rosetta Branch of River Nile exposed to high input of agricultural drainage water, sewage and industrial waste water which influence the living organisms especially fish. In the present study, results revealed that high concentrations of heavy metals (Fe, Zn, Cu, Mn and Cd) were detected in water and fish samples, especially in winter. In muscles of O. niloticus, the accumulation patterns of heavy metals were in the following order: Fe > Zn > Mn > Cu and Cd. The bioaccumulation factor (BAF) in winter was higher than summer. Antioxidant enzymes (SOD, CAT, GPx, GST and GR) activities and the indicator of lipid peroxidation MDA levels in liver and white muscles of O. niloticus were found to be significantly increased compared to the reference values, especially in winter. Moreover, the antioxidant enzymes activities and MDA levels were higher in liver than white muscles. These remarkable alterations in the activity of the selected enzymes in the liver and white muscles of the O. niloticus go in parallel with the elevation in the levels of heavy metals detected in the water of Rosetta branch, as a result of pollution stress in these areas. Thus we conclude that, the altered activities of SOD, CAT, GPx, GST and GR) and MDA levels could be useful biomarkers of water pollution.

“…However, heavy metals pollution in shrimp has become an important worldwide concern, not only because of the threat to shrimp, but also due to the non-carcinogenic health risks related with shrimp consumption. For example, renal failure and liver damage may occur due to the presence of lead in food [10] . Prolonged exposure to lead can result in coma, mental retardation and even death [2] .…”

This study is aimed to assess the heavy metals contamination and health risk in Shrimp (Macrobrachium rosenbergii and Penaeus monodon) collected from Khulna-Satkhira region in Bangladesh. The results showed that the Pb concentrations (0.52–1.16 mg/kg) in all shrimp samples of farms were higher than the recommended limit. The Cd levels (0.05–0.13 mg/kg) in all samples and Cr levels in all farms except tissue content at Satkhira farm were higher than the permissible limits. The individual concentration of Pb, Cd, and Cr between shrimp tissue and shell in all rivers and farms were not statistically significant (P > 0.05). Target hazard quotient (THQ) and hazard index (HI) were estimated to assess the non-carcinogenic health risks. Shrimp samples from all locations under the current study were found to be safe for consumption, the possibility of health risk associated with non-carcinogenic effect is very low for continuous consumption for 30 years.

“…For example, Cd damages the kidney and may cause chronic toxic symptoms such as tumors, hypertension, adverse reproductive capacity, hepatic dysfunction and impaired kidney function (Al-Busaidi et al, 2011). Similarly, Pb induces renal insufficiency and liver injury (Lee et al, 2011). Furthermore, long-term exposure to Pb may end up coma, mental retardation and even death (Al-Busaidi et al, 2011).…”

Aim of this study was to measure cadmium and lead concentrations in the edible tissues of Saddle grunt Pomadasys maculatus (Bloch, 1793) from Karachi Fish Harbor different seasons of the year 2011. Results showed that the concentration varied from 0.18 to 1.14 with a mean of 0.59 ± 0.05 mg.kg-1 for Cd and from 0.02 to 1.54 with a mean of 0.54 ± 0.05 mg.kg-1 for Pb. These concentrations are higher than the maximum permissible values in European and other international regulations (Global Agricultural Information Network Report for China, Russian Federation , Australia New Zealand Food Standards, Georgian Food Safety Rules, Turkish Food Codex and the Ministry of Agriculture, Fisheries and Food). However the average weekly intakes of Cd and Pb per body weight values (minimum-maximum) were 0.021 (0.0063-0.0399) and 0.019 (0.0007-0.0539)mg.week-1.70 kg body weight-1, respectively and not exceeded the Provisional Tolerable Weekly Intake (PTWI) established. Consumption of Saddle grunt from the Karachi coasts of Pakistan can therefore be said to constitute no health risks so far as the heavy metals investigated are concerned. However, due to the Cd and Pb muscle levels exceeded the maximum levels of fish permitted for human consumption, a plausible health risk could be posed by long-term exposed through Saddle grunt consumption.
