“…Pb depuration was significantly higher that Zn and Ni from fish body. Ni compounds are toxic to the fish due to Ni-induced toxicological, physiological and histopathological alterations in fish (Gupta et al, 2006;. Bio-accumulation of metals reflects the amount ingested by the organism, the way by which metals are distributed among different tissues and the extent of metals retention in each tissue type (Murugan et al, 2008).…”

To cite this paper: Javed, M., 2015. Growth and metals depuration in Zn+Pb+Ni mixture stressed fish grown under composite pond culture conditions. Int. J. Agric AbstractThe growth performance and metals depuration abilities of Zn+Pb+Ni stressed five fish species viz. Cirrhina mrigala, Hypophthalmichthys molitrix, Labeo rohita, Ctenopharyngodon idella and Catla catla were studied under composite pond culture conditions. All fish species were stressed with metals mixture at their 1/3 rd LC 50 for one month. After stress, the fish were grown in ponds under composite culture conditions for 120 days to realize their growth and metals depuration potentials when grown in stress-free environment. Among treated fish, C. mrigala exhibited significantly better growth, followed by L. rohita, C. idella, H. molitrix and C. catla while growth in control fish followed the order: C. catla ≥ L. rohita > C. mrigala > C. idella > H. molitrix. Both control and treated fish species displayed significant variations in their weight, length, condition factor and specific growth rates that correlated positively (p<0.01) with water temperature and feed conversion efficiency (FCE). Rearing of treated fish in metals deprived environment caused variable retention of selected metals in their body organs as kidney > liver > skin > muscle > fins ≥ gills ≥ bones. C. idella retained significantly higher metals in its body, followed by C. catla and H. molitrix with non-significant differences. Pb retention was significantly higher in fish body, followed by Zn and Ni. The liver of treated fish showed significantly higher depuration of metals (94.06%) while it was lowest (66.06%) in bones. C. catla exhibited significantly higher metal's depuration tendency (96.44%), followed by L. rohita (93.11%), C. idella (93.02%), C. mrigala (89.35%) and H. molitrix (82.60%) with significant differences at p < 0.05. The tendency of fish to depurate Pb from its body was significantly higher (177.94%), followed by Zn (131.13%) and Ni (38.26%).

“…Together with the decrease in pH, the dissociation of carboxyl group of amino acids decreases (at pH = 2 it is totally receded). Under such conditions, a strong protonation of the amine group to NH 3 + takes place, which allows for a conclusion that in a strongly acid environment the amino acid particles are present in the form of a positive ion [16,23]. Biosorbents (DP95Ca and ER95Ca) developed on the basis of the marine alga Durvillaea potatorum and Ecklonia radiate sorbed 90% of the determined metal ions at pH = 4.5.…”

Abstract:The publication is a synthetic collection of information on the sorption properties of marine and freshwater algae. Kinetics and sorption equilibrium of heavy metals in algae-solution system, influence of abiotic factors on the process of sorption and desorption of analytes from biomass are discussed. In paper the results of laboratory tests conducted using different species and types of algae, which purpose was to assess their usefulness as natural sorbents, are described. The conclusions drawn from current research confirm the results from literature.

Hydrotalcite-like compound (HTlc) with a Mg/Al molar ratio of 2∶1 was synthesized by using a coprecipitation method and the sorption removal of Cu(II) by the Mg-Al HTlc sample from CuSO 4 solution was investigated. It was found that the Mg-Al HTlc showed a good sorption ability for Cu(II) from CuSO 4 solution, indicating that the use of hydrotalcite-like compounds as promising inorganic sorbents for the removal of heavy metal ions from water is possible. The sorption kinetics and the sorption isotherm of Cu(II) on the HTlc obeyed the pseudo-second order kinetic model and Langmuir equation, respectively. The percent removal of Cu(II) by the HTlc was strongly dependent on the initial pH of bulk solution. It increased sharply with the increase of initial pH value in the range of 5-7, and was relatively small in the initial pH range of 4-5, while it reached about 100% after initial pH was higher than 7. The presence of AlCl 3 might obviously lower the equilibrium sorption amount (q e ) of Cu(II) on the HTlc. However, the presences of NaCl and MgCl 2 might increase the q e . The presences of ligands (citric acid and EDTA) in the studied concentration range might obviously decrease the q e of Cu(II) on the HTlc. The removal mechanism of Cu(II) cations by HTlc in the presence of 2 4 SO anions may be attributed to the surface-induced precipitation of Cu(II) hydroxides and the surface complex adsorption by the linking effect of 2 4SO between the HTlc and Cu(II) cations, and the removal ability arising from the surface-induced precipitation is much higher than that from the linking effect of 2 4 SO -.
