    The Influence of Qatari Dust on the Element Composition of Marine Plankton حسب Yigiterhan, Oguz

    منشور في 2021
    "…The biogenic concentrations of trace metals were determined by correcting the bulk analyses for the lithogenic contribution using aluminum content of Qatari dust as a lithogenic tracer. The relative trace metal composition of plankton from EEZ of Qatar is Fe > Zn ≈ Cu > V ≈ Ni ≈ Cr ≈ As ≈ Mo > Cd ≈ Co. …"
