    Assessment Of Heavy Metal Pollution Of Waste Dump Sites In Kwara State Using Carica Papaya, Musa Spp And Cocorhrous Olitorous As Indicators
    (International Organization of Scientific Research (IOSR), 2013-09) Bale, Adebayo Tajudeen; Ogundele, Damilola Temitope; Bodunde, Victoria Tosin
    Plant fruits and vegetables grown on mixed waste dumpsites were used as bio indicators of heavy metal pollution of three waste dumpsites in Ilorin Kwara State Nigeria. The samples were digested using Wet-oxidation method and heavy metals in the digest were analyzed by Atomic Absorption Spectrophotometer Technique. Carica Papaya, Musa Spp and Cocorhrous Olitorous samples were collected from contaminated and uncontaminated sites. Copper concentrations of carica- papaya, Musa spp, and cocorhrous olitorous from the contaminated sites were found between 0.15-0.23 mg/kg in Abayawo, 0.13 mg/kg in Okolowo, and 0.10 mg/kg in Itanmo. Zinc was found between 21.25-42.75mg/kg in Abayawo, 20.00 mg/kg in Okolowo, and 11.00 mg/kg in Itanmo. Pb and Cd were found below the detection limit of the instrument. Heavy metals in the uncontaminated site samples were found between 0.10-0.23 mg/kg Copper, 0.75-31.75 mg/kg Zinc. Cadmium and lead were found comparatively below detention limits in all the samples. Mean concentrations of metals were higher in Abayawo dumpsite than other dumpsites. The mean concentration of Cu 0.56 mg/kg and Zn 30.75mg/kg are well above the mean concentration of metals from the control site (Oloje) 0.15 mg/kg and 24.58 mg/kg Copper and Zinc respectively. Base on this study, the three waste dumpsites are polluted with heavy metals (Copper, Zinc), which can pose great health risk and hazards on food chain.

    Comparative Studies of the Physicochemical Properties of Moringa oleifera (Nigeria), Moringa oleifera (Kenya) and Moringa oleifera (India)
    (Longdom Publishing SL, 2015) Bale, Adebayo Tajudeen; Olubuade, Fatimah Eniola; Ogundele, Damilola Temitope; Olayemi, Victoria Tosin; Jimoh, Akeem Adebayo; Musa, Rukayat Titilayo
    The oil from Moringa oleifera seeds obtained from Afon in Asa Local Government Area of Kwara State, Nigeria, was extracted using n-hexane. The oil yield determined experimentally was 26.2%. The oil concentration was compared with those reported by [1,2]. Some physicochemical properties like the density, specific gravity, refractive index, pH, viscosity, acid value, peroxide value, saponification value, iodine value and FFA were determined. The results obtained were compared against previously reported data.
