    Assessment of heavy metals contamination in Mamut river sediments using sediment quality guidelines and geochemical indices
    (Springer, 2015) Bibi Noorarlijannah Mohammad Ali; Chin Yik Lin; Fera Cleophas; Mohd Harun Abdullah; Baba Musta
    This paper describes the concentration of selected heavy metals (Co, Cu, Ni, Pb, and Zn) in the Mamut river sediments and evaluate the degree of contamination of the river polluted by a disused copper mine.

    Distance impacts toxic metals pollution in mining affected river sediments

    The study of metals mobility derived from mining activities in an ultramafic lithology is limited. This study investigates the effects of distance on potentially toxic metals such as Co, Cu, Fe, Mn, Ni, Pb, and Zn pollution, and the geochemical processes of fluvial system downstream of an ex-copper mine (Mamut River). The toxicity level of the river was evaluated using various sediment quality guidelines, ecotoxicological risks (ecological risk and risk index) and pollution indices. The geochemical behavior and stability of these toxic metals in the solid-phase samples were also examined.
