“…However, in this study, most of the metals (Zn, Cu, Cd, Pb, and Ni) accumulated at the lowest concentrations in all the tissues selected for the purpose of this research (liver, gills, bone, skin, and muscle) for all the paddy seasons. These results mirror those of the past studies 16,22,39 .…”

This work investigates the metals concentration in the tissues of Asian swamp eel, Monopterus albus . Five selected tissues, including liver, gill, bone, skin, and muscle were examined for the concentration of Zn, Cu, Cd, Pb, and Ni. The concentrations of Cd and Pb were found high in the muscle tissues of the eels. Additionally, high amounts of Zn and Cu metals were observed in the liver, whereas the Cd, Pb, and Ni metals were highly detected in gill. The accumulation of Zn, Cu, Cd, Pb, and Ni in both skin and bone of the eel seems to vary between seasons. Low levels of Zn, Cu, and Ni were identified in the muscle tissues of the eels. This study revealed that the concentration of Cd and Pb in the muscle tissues of Asian swamp eels exceeded the permissible limits by the US EPA, suggesting the consumption of the muscle may be hazardous and can severely affect one’s health.

“…Highest accumulation was observed in liver and least in integument. In other studies as well the liver reported to accumulate high concentrations of Ni in fishes such as Labeo umbratus (Coetzee et al 2002), Oreochromis niloticus (Taweel et al 2012), Cirrhinus mrigala (Javed 2012) and least in integument of Clarias gariepinus , Channa punctatus (Javed and Usmani 2012a). Accumulation of Ni in muscle of M. armatus was below the permissible limits (70–80) set by USFDA (1993b).…”

“…Similarly many water bodies which lie in vicinity of population have been polluted by effluents released by industries, factories, Power stations, domestic waste etc. which besides disturbing the quality of water also degrade the protein source in the form of fish food and limits their use (Baki et al 2011; Abdul Qadir and Riffat Naseem 2011; Javed and Usmani 2012b2013a; Taweel et al 2012; Emere and Dibal 2013; Fatima and Usmani 2013). In the present study possible reason for high levels of heavy metals in rivulet water could be attributed to the fact that this Power Station may not have efficient wastewater treatment plant.…”

The present study was conducted to examine the contamination of rivulet situated at Kasimpur, Aligarh (27.218° N; 79.378° E). It receives the wastewater of Harduaganj Thermal Power Plant (HTPS) containing fly ash and heavy metals. Among the heavy metals estimated in the rivulet water, Fe (8.71 mgL-1) was present in the highest concentration followed by Cu (0.86 mgL-1), Zn (0.30 mgL-1) Mn (0.21 mgL-1), Ni (0.12 mgL-1), Co (0.11 mgL-1) and Cr (0.10 mgL-1). The values for the heavy metals such as Fe, Ni and Mn were beyond the limits set by UNEPGEMS. Bioaccumulation of these heavy metals was detected in tissues such as gills, liver, kidney, muscle and integument of the fish Mastacembelus armatus. Accumulation of Fe (213.29 – 2601.49 mgkg-1.dw) was highest in all the organs. Liver was the most influenced organ and integument had the least metal load. The accumulation of Fe, Zn, Cu and Mn, observed in the tissues were above the values recommended by FAO/WHO. Biochemical estimation related to blood glucose, liver and muscle glycogen conducted showed significant (p < 0.01) elevation in blood glucose content over control (17.73%), whereas liver glycogen dropped significantly (p < 0.01) over control (−89.83%), and similarly muscle glycogen also decreased significantly (p < 0.05) over control (−71.95%), suggesting enhanced glycolytic capacity to fuel hepatic metabolism. Histopathological alterations were also observed in selected organs (gills, liver and kidney) of Mastacembelus armatus.

“…There was also elevation of lipid peroxidation, and since these changes were prevented by vitamins C and E, the authors attributed the findings of increased oxidative stress to ZnO nanoparticles. In the study by Tawell et al (2012), between 11-16 ppm Zn +2 was found in tilapia muscle, an acceptable amount for human consumption. Dwivedi et al (2015), on the other hand, found low level of Zn +2 contamination in tilapia muscle, but which slightly exceeded the limit for consumption.…”

Fish is one of the healthiest food sources once it has proteins, vitamins, minerals and the omega-3 polyunsaturated lipids. Nevertheless, to be healthy, the protein in fish meat must not have contaminants further than allowed. This study aimed to investigate the preclinical toxicologic effects of consumption of fish meat from Cachoeira river (Joinville, Santa Catarina, Brazil). Groups of rats were divided and received for a month: standard ration, farmed fish meat and fish meat from Cachoeira river twice a week. One day after the last exposition, animals were euthanized and blood, spleen, heart, liver, kidney, cerebellum, and cerebral cortex were collected to measure oxidative stress, biochemical and hematological parameters. Metals levels were also analyzed in fish meat by atomic emission spectrometry. Significant elevation of carbonylated proteins were observed in heart and liver and thiobarbituric acid reactive substances in liver, plasma and cerebellum were observed. Total sulfhydryl content decreased significantly in cerebellum, liver and heart, and decreased catalase activity in the liver and superoxide dismutase activity in the kidneys were also present among rats who consumed fish meat from Cachoeira river. No modification of hematological parameters was observed, and only significant decrease of HDL occurred among biochemical parameters. Analysis of metals in river fish meat showed a fivefold increase in zinc and aluminum compared to farmed fish meat. Short-term exposure to fish meat from the Cachoeira River resulted in increased oxidative stress, liable to be transferred through the food chain, possibly associated with the increased presence of heavy metals.
