    Analysis of heavy metal concentrations in sediments of selected estuaries of Malaysia - a statistical assessment
    (Springer, 2009) Abbas F. M.; Alkarkhi; Norli Ismail; Aness Ahmed; Azhar mat Easa
    Statistical analysis of heavy metal concentrations in sediment was studied to understand the interrelationship between different parameters and also to identify probable source component in order to explain the pollution status of selected estuaries. Concentrations of heavy metals (Cu, Zn, Cd, Fe, Pb, Cr, Hg and Mn) were analyzed in sediments from Juru and Jejawi Estuaries in Malaysia with ten sampling points of each estuary.

    Characterization of landfill leachates and its impact to groundwater and river water quality: A case study in Beris Lalang waste dumpsite, Kelantan
    (Universiti Pertanian Malaysia Press, 2019) Widad Fadhullah; Mohamad Anuar Kamaruddin; Norli Ismail; Nurulilyana Sansuddin; Hasmah Abdullah
    Solid waste management in developing countries including Malaysia is dominated by waste dumpsites which have a high possibility of transporting organic and inorganic pollutants to the underlying groundwater and surface water within the surrounding area. The objective of this study is to characterise the landfill leachates and its surrounding groundwater and river water quality and metals concentrations, namely arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) from Beris Lalang, Kelantan.

    Multivariate analysis of heavy metals concentrations in river estuary
    (Springer, 2008) Abbas F. M. Alkarkhi; Anees Ahmad; Norli Ismail; Azhar Mat Easa
    Multivariate statistical techniques such as multivariate analysis of variance (MANOVA) and discriminant analysis (DA) were applied for analyzing the data obtained from two rivers in the Penang State of Malaysia for the concentration of heavy metal ions (As, Cr, Cd, Zn, Cu, Pb, and Hg) using a flame atomic absorption spectrometry (F-AAS) for Cr, Cd, Zn, Cu, Pb, As and cold vapor atomic absorption spectrometry (CV-AAS) for Hg. The two locations of interest with 20 sampling points of each location were Kuala Juru (Juru River) and Bukit Tambun (Jejawi River).
