    Cynodon Dactylon is a great tool to rehabilitate the ecosystem on tailing dam, as it is capable of absorbing a wide range of metals and heavy metals of the dams including Mn, Zn, Cu, Pb, Cd, Co it can grow well in the very low pH of the damaged soil.

  • Trace Element Distributions in NRC Research Press

    The distribution patterns of trace element contaminants (As, Cd, Cu, Pb, Zn) among the tissues of freshwater insects (Chironomus, Clinotanypus, Procladius, Hexagenia, Sialis) are both taxon and element specific.In quantity terms (micrograms per animal), the gut is the major organ of Cd accumulation, while most of the As, Cu, Pb, and Zn accumulates in the body (i.e. animal minus gut

  • Are Catfish (Ariidae) Effective Bioindicators for Pb, Cd

    The Zn and Cu concentrations probably reflect normal levels without a significant influence of anthropogenic contamination. The levels of Cd and Pb in muscle tissue of C. spixii and G. genidens were relatively low, but the PCA indicated the presence of the levels of these metals in the reference area (thereby supporting the need for monitoring

    contaminated with high levels of Cu, Zn, Ni and Pb in water and Cu and Zn in sediment The metal concentrations in biota were generally higher in sedimentation ponds than in the control ponds The observed variation in the data could be explained by a pond factor and a species factor (dragonflies > mayflies > damselflies)

    PType ATPase Heavy Metal Transporters The Plant Cell

    insects, plants, and mammals. In prokaryotes, the metal substrates of these transporters include Cu, Zn, Cd, Ag, Pb, and Co ions, and in most cases, individual transporters confer tolerance to the metal ion substrate through acting as an efflux pump (Rensing et al., 1999). However, some type 1 B ATPases in
