Abstract This study examined drivers’ perception of road traffic delay attributes and factors influencing road traffic delay with a view to assessing loss of man hours along Lagos-Abeokuta Expressway. This view translated to policy statements that can tremendously reduce the road traffic delay in the study area. Primary data were collected through questionnaire administration, traffic […]
SPECIATION AND MOBILITY STUDY OF SELECTED HEAVY METALS IN KOFE DUMPSITE SOIL OF JIMMA TOWN, JIMMA, ETHIOPIA
Abstract Speciation and mobility of selected heavy metals including Cd, Pb and Fe were investigated in Kofe dumpsite soils of Jimma Town, Jimma, Ethiopia. To study vertical mobility of the metals, soil samples were collected at three depth profiles comprising surface soil (0-10 cm), subsoil (20-30 cm), and bottom soil (40-50 cm) using soil auger. […]

EFFECT OF LABORATORY PRODUCED XYLANASE FROM Aspergillus niger ON FIBRE DIGESTIBILITY OF RICE HUSK AND GUINEA GRASS
Abstract The efficacy of laboratory produced xylanase enzyme from Aspergillus niger on highly fibrous feeds and feedstuffs was investigated. Guinea grass (Panicum maximum) from grass hay and rice husk (Oryza sativa) from crop by-product characterised with high fibre content served as substrates (Feeds and Feedstuffs) for the experiment. The enzyme xylanase was prepared from Aspergillus […]
ASSESSMENT OF LABILE METALS IN EFFLUENTS FROM LUBRICATING OIL COMPANY IN OSOGBO OSUN STATE, NIGERIA
Abstract Effluent and sediment samples were collected on seasonal basis, comprising of three months (August to October) in the wet season and three months (December to February) in the dry season from five points around a lubricating oil company in Osogbo – Nigeria. The sequential extraction method was used to respectively fractionate the sediment and […]
RATE OF LAND COVER CHANGE AND ITS DETERMINANTS IN THE SOUDANO-GUINEA TRANSITION ZONE OF BENIN REPUBLIC
Abstract The paper assesses land cover dynamics and its associated drivers in the soudano-guinea transition zone of Benin Republic, using both spatial and non-spatial data. Multispectral and multi temporal Landsat imageries (Landsat TM of 1986, ETM+ of 2000 and OLI-TIRS of 2013) were used for the analysis of land cover dynamics through a supervised classification. […]
HEALTH RISK OF HEAVY METALS IN Celosia argentea L. GROWN ON MUNICIPAL WASTE SOILS IN IBADAN, NIGERIA
Abstract This paper assessed the appropriateness of dumpsites in Urban and Peri-urban Agriculture (UPA). The bioaccumulation and potential heavy metal-toxicity risk of consuming Celosia argentea L. grown on four different dumpsites soils (Ajibode, Sasa, Moniya and Akinyele) and reference soil from University of Ibadan Training and Research Farm was also evaluated. The soil samples were […]
