    Assessment of surface water quality of selected estuaries of Malaysia: multivariate statistical techniques
    (Springer, 2008) Abbas F. M. Alkarkhi; Anees Ahmad; Azhar Mat Easa
    Multivariate statistical techniques such as cluster analysis (CA), factor analysis (FA) were used for the evaluation of spatial variations and the interpretation of a large complex water quality data set of two selected estuaries of Malaysia. The two locations of interest with 10 sites in each location were Kuala Juru (Juru estuary) and Bukit Tambun (Jejawi estuary).

    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).
