    Sediment Heavy Metals Distribution in Relation to Grain Size at Johor Port: East Coast Peninsular Malaysia
    (Journal of Earth Sciences, 2015) Nor Antonina Abdullah; Noor Azhar Mohd Shazili; Raja Samsul; Lina Idayu Abdullah; Shaufi Sokiman
    A total of 20 surficial sediment samples were collected from Johor Port, East Coast of Peninsular Malaysiaon May 2014 by using Smith McIntyre grab. These sediments were analyzed for its grain size using particle size analyzer (PSA) to find out the relationship between grain size and heavy metal concentrations. The concentration of heavy metals were measured from the 63 um fraction of the dried sediments and analyzed using ICPMS. The heavy metals studied were: Fe, Mn, Zn, Cr, Cu, Ni, Pb, As, Co, Cd and Hg. Results showed that the study area was dominated with silt loam (90%) and same percentages of loamy sand (5%) and sandy loam (5%).

    A Study on clay minerals and major element oxides in surface riverine estuarine sediments from selected from selected rivers of Terengganu, Malaysia
    (Terengganu: Universiti Malaysia Terengganu, 2015) Lina Idayu Abdullah
    The clay mineralogy deposition and major oxide elements distribution of the surface estuarine sediments from the selected estuaries of Terengganu was studied in order to know the types of clay minerals and the source of sediments. A total of 68 sampling stations were collected from the estuaries of Terengganu River, Kemaman River, Dungun River and Besut River. The sediments were examined using X-ray Diffractometer (XRD) and Scanning Electron Microscope with Electron Dispersive X-ray Spectroscopy (SEM-EDS) methods for the clay minerals present and major oxides composition.
