  • Zinc Homeostasis and isotopic fractionation in plants a

    Dec 27, 20160183;32;Zinc is an essential micronutrient for living organisms with several crucial functions in the cell. It is the only metal present in enzymes of all six major classes, playing catalytic, regulatory, and structural roles (Vallee and Auld 1992; Coleman 1992).Zinc is furthermore involved in the regulation of DNA transcription, and the transduction of intra and intercellular signalling (Broadley et

  • Speciation of Trace Metals Pb, Zn, Cu and Cd in Surficial

    Trace metals (Zn, Pb, Cu, Cd) speciation of surface sediments from Makupa creek, coastal Kenya were determined by sequential extraction procedure. The procedure was used to extract the trace metals in sediments geochemical phases (exchangeable, carbonates, Fe Mn oxides, organic matter/sulphide, and residual). Trace metals analysis was done using ICP/MS.

  • Immobilization of Zn, Cu, and Pb in contaminated soils

    The phytoavailability of Cu and Zn was positively correlated to their water solubility (r = 0.907 and 0.825 for soybean Cu and Zn, respectively; r = 0.946 and 0.861 for lettuce Cu and Zn, respectively). Among the three metals, P amendments were effective in reducing Pb phytoavailability, compared to Cu and Zn.

  • RECOGNIZING MANTLE PLUMES IN THE GEOLOGICAL RECORD

    Mantle plumes are recognized by domal uplift, triple junction rifting, and especially the presence of a large igneous province (LIP), dominated in the Phanerozoic by flood basalts, and in the Proterozoic by the exposed plumbing system of dykes, sills, and layered intrusions. In the Archean, greenstone belts that contain komatiites have been linked to plumes. In addition, some carbonatites and
