    Review of the Sedimentological and Geochemical Approaches for Environmental Assessment of River Sadong, Samarahan-Asajaya District Sarawak, Malaysia
    (Nature Environment and Pollution Technology, 2019) Omorinoye, O.A.; Assim, Z.B.; Jusoh, I.B.; Durumin-Iya, N.I; Umaru, I.J.
    This paper presents an overview of the implication of geomorphology and sedimentology on the chemical characteristics of sediments of River Sadong, Malaysia. There is limited published work on the effect of topography, climate, soil and geology on the sediments lying in the River Sadong. Studies have been undertaken around Kota Samarahan and Asajaya areas whereby some heavy metal constituents and their environmental effects were determined. The study entails the description of the depositional processes alongside with physical and geochemical changes, without neglecting natural and anthropogenic effects.

    Vertical Profile of Heavy Metal Concentration in Sediments from Sadong River, Sarawak, Malaysia
    (Indian Journal of Environmental Protection, 2019) Omorinoye, O.A.; Assim, Z.B.; Jusoh, I.B.; Durumin-Iya, N.I; Asare, E.A.
    Several sources of heavy metals in the environment include biological, geochemical, geological and anthropogenic sources. A total of eighteen core sediments were taken form Sadong river, Sarawak, Malaysia. These samples were digested by acid extraction and thereafter subjected to Atomic Absorption Spectrometry (AAS). This paper aims to determine the vertical profile of heavy metals in core sediments, infer the accumulation history and assess the possible sources of pollution. The result showed that Fe was the most abundant element wile Cd had the lowest concentration. Sediment pollution assessment was carried out for the top layer using geoaccumulation index (Igeo), enrichment factor and contamination factor. EF values showed moderate to significant enrichment of heavy metals.
