Item Accumulation and Translocation of Heavy Metals by Acalypha wilkesiana Parts in the Phytoextraction of Contaminated Soil(Indonesian Journal of Chemistry, 2019) Iya, N.I.D.; Assim, Z.B.; Ipor, I.B.; Omorinoye, O.A.; Umaru, I.J.; Jume, B.H.This study was to investigate survival, growth and accumulation potential of Acalypha wilkesiana in phytoextraction of heavy metals contaminated soil. Acalypha wilkesiana was tested to evaluate its tolerance and phytoextraction capacity in soils contaminated with metals. It was tested under 10 mL of 100 mg/kg of As, Cr, Cd, Co, Cu, Fe, Mn, Ni, Pb, and Zn solution, along 240 days in greenhouse experiment with harvesting period of 60 days interval. Twenty four cuttings from Acalypha wilkesiana were subjected to the same treatment. Plants roots stem and leaves were dry-digested and analyzed using Atomic Absorption Spectrophotometer (AAS). Results show that Fe was the most accumulated metal followed by Cu, Mn, As and Zn with 5002.4, 542.7, 492.2, 396.7 and 308.2 mg/kg, respectively. The concentration of Cr, Ni, and Co was 101.2, 99.09, and 89.63mg/kg respectively. The highest concentration of Pb was 46.44 mg/kg, Cd was not detected by the plant. Bioconcentration Factor (BCF) of metals were above unity in root, stem, and leaf except for Fe which showed a value below the unity, and Pb shows highest BF value of 7.79. The Translocation Factor (TF) of Cr, Co, Fe, Ni, and Pb were higher, while that of As, Cu, Mn, and Zn were below the unity, Co showed the highest value of 15.93. Furthermore, Extraction Coefficient (EC) of Cr, Co, Ni, and Pb were greater than 1, while for remaining metals were lower than unity, the highest EC was observed from Pb with a value 17.21.Item Concentration of Polycyclic Aromatic Hydrocarbon (PAH) in Roots and Leaves of Polyscias fruticosa used in Phtyoextractionof Crude Oil Spiked Soil(UMYU Journal of Pure and Industrial Chemical Research; Department of Pure and Industrial Chemistry, Umaru Musa Yar'adua University Katsina, 2022) Durumin-Iya, N.I; Assim, Z.B.; Omorinoye, O.A.; Asare, E.A.; Adamu, Y.A.; Eri, S.M.Item Contamination and Risk Assessment of Heavy Metals from Sadong River, Malaysia(2021) Omorinoye, O.A.; Assim, Z.B.; Adedoyin, A.D.; Bamigboye, O.S.Item Geochemistry of Aliphatic Hydrocarbon Compounds in Core Sediments from Sadong River, Malaysia(FUW Trends in Science & Technology Journal; Federal University Wukari, 2023) Omorinoye, O.A.; Assim, Z.B.; Bamigboye, O.S.; Alebiosu, M.T.Item Geomorphological and Sedimentological Features of River Sadong, Sarawak, Malaysia(Indonesian Journal on Geoscience, 2021) Omorinoye, O.A.; Assim, Z.B.; Jusoh, I.B.Item Phytoremediation of Copper and Lead from Spiked Soil Using Acalypha Wilkesiana (Copper leaf) and Polyscias fruticosa (Aralia)(Dutse Journal of Pure and Applied Sciences; Faculty of Science, Federal University Dutse, Jigawa State, 2022) Durumin-Iya, N.I; Assim, Z.B.; Omorinoye, O.A.; Asare, E.A.Item Phytoremediation of Heavy Metals from Landfill Using Polyscias fruticosa(Faculty of Science, Bayero University, Kano, 2022) Durumin-Iya, N.I; Assim, Z.B.; Omorinoye, O.A.; Asare, E.A.Item Phytoremediation of Soil Spiked with Crude Oil Using Acalypha Wilkesiana Plant(UMYU Journal of Pure and Industrial Chemical Research; Department of Pure and Industrial Chemistry, Umaru Musa Yar'adua University Katsina, 2021) Durumin-Iya, N.I; Assim, Z.B.; Omorinoye, O.A.; Samling, B.; Asare, E.A.; Ajlan, N.B.Item 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.Item 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.
