Impact Of Oil Spillage On The Water Quality Of Abuloma River In Port-harcourt, Rivers State

ABSTRACT The activity of the oil prospecting companies in the study area is mainly that of crude oil extraction from the subsurface. As a result of these petroleum activities, there is a continuous destruction of aquatic lives – flora and fauna destabilizing the entire aquatic eco-system. This study was focused on the impact of oil spillage on the water quality. Different physico-chemical parameters were analyzed, including Temperature, Taste, Colour, Odou...

Geotechnical Assessment Of Gully Erosion Site In Umuagor Urualla, Imo State South Eastern Nigeria

ABSTRACT Erosion is one of the major environmental hazards currently ravaging the southeastern part of Nigeria, especially Imo-state. This present study was conducted to assess the impact of Umuagor-Urualla gully erosion site. Analysis of undisturbed soil samples collected at three distinct positions (surface, subsurface and base of the gully) showed that the liquid limit and plastic limit for sample 1 was NP (non-plastic), with Plasticity Index of 0%, while the Plasticity Index for samp...

Effectiveness Of Microbial Load On The Removal Of Total Petroleum Hydrocarbon From Drill Cuttings

ABSTRACT Petroleum hydrocarbons (PHCs) are common site contaminants, but they are not generally regulated as hazardous wastes. TPH refers not only to analytical results, but also to environmental and health properties of PHCs. Biodegradation by natural populations of microorganisms represents one of the primary mechanisms by which petroleum and other hydrocarbon pollutants can be removed from the environment and is cheaper than other remediation technologies. The environmental implication ass...

Effect Of Drilling Waste On Soil Quality At Opukushi Community In Delta State

ABSTRACT The effect of drilling waste on soil quality was studied at Opukushi Oil field dumpsite in Delta state. The period of sampling and analysis was between June and September 2010. Soil samples from the dump sites and the control site were physicochemical analyzed using Gas Chromatography, Atomic Absorption Spectrophotometer (AAS). Laboratory analysis were conducted according to standard methods. Descriptive statistical analysis was used to obtain range, means, standard errors, as w...

Assessment Of Variation In The Concentration Of Heavy Metals In Groundwater Within Oil Producing Community Ogba/Egbema/Ndoni L.G.A. Rivers State

ABSTRACT Groundwater constitutes a major source of potable water supply foragricultural, industrial and domestic applications. This has led to the increase in the demand for ground water exploitation. Borehole water being an ideal source of portable water supply has been employed to meet this teeming demand. For the purpose of this research, borehole water was adopted as a sample model for the experiment to determine the extent of heavy metal contamination in the ground water of...

Assessment Of Post-Spill Impact On Soil, Case Study (K.Dere) Ogoni Land

ABSTRACT The supply of food, water, and agricultural resources is fast becoming a difficult issue. This is because the resources are heavily polluted as a result of intensive crude oil spill, and oil related activities in the state. This study focused on the assessment of soil samples from Ogoni, (k- Dere) community. To ascertain the level of pollution that may have occurred. Different parameters were analyzed, namely pH, total petroleum hydrocarbons, nitrate, phosphate, sulphate,...

Primary Productivity of The Middle Reaches of The Otamiri River; The Role of Temperature And Nutrients

ABSTRACT    The possible roles of temperature and nutrientson Primary productivity of the Middle Reaches of Otamiri River in the Federal University of Technology, Owerri, Nigeria was investigated between October and November, 2016. Ten sampling points (OTP1 – OTP10) sited about 50m apart were studied. The light and dark bottle technique was used for the estimation of primary productivity and in situ measurements was made for water temperature. Other parameters were determine...

Plant Extracts Of Mucuna Pruriends As An Environmental Friendly Corrosion Inhibitor For Mild Steel In Acidic Environments

ABSTRACTThe inhibiting effect of aqueous extracts of MucunaPruriends (MP) on mild steel corrosion in 1 M HCl and 0.5 M H2SO4solution was investigated using weight loss and electrochemical techniques. The results revealed that MP inhibited the corrosion reaction. Polarization data reveal that the extract functioned as a mixed-type inhibitor. Inhibition efficiencies of the inhibitor increased with concentration of the extract but decreased gradually with an increase in the period of immersion. ...

Comparison Of Morphological Changes Along The Arcuate Niger Delta Coastline (From Part Of Delta State To Part Of Rivers State

ABSTRACTThis study analysed the rate of coastal erosion and accretion along the Niger Delta coastline. The study compared Morphological changes along Ogulagha (Delta State), Twon-Brass (Bayelsa State) And Bonny Island (River State) coastlines over a period of 30 years (1986-2000-2016). Geospatial techniques were used to carry out the assessment. Satellite image of landsat 5 Thematic Mapper (TM) of December 1986, landsat 7 and 8, Enhance Thematic Mapper (ETM+) of December 2000 and 2016 of path...

EFFECTIVENESS OF Mimosa Pudica EXTRACTS AS A BENIGN ANTI-CORROSION ADDITIVE

ABSTRACTThis research investigated the suitability of Mimosa pudica leaf (MPL) and Mimosa pudica stem (MPS) extracts as an inexpensive and nontoxic corrosion inhibitor for mild steel in acidic environment. The experiments carried out to investigate the corrosion inhibition of mild steel in 1.0 M HCl and 0.5 M H2SO4 by Mimosa pudica leaf and stem extract were weight loss and potentiodynamic polarization methods to determine the extract adsorption potential, kind of protection and its corrosion...

Comparative Study of Contamination And Distribution of Heavy Metals in Quary Soils And Accumulation in Cassava (Manihot esculentum) in Eziama, Umunochi, Abia State Tuber

ABSTRACT    The contamination of agricultural soil by quarrying activities has environmental and health implications especially the effect on bioaccumulation. Comparative study of contamination and distribution of heavy metals in three different quarry sites of Eziama in Umunnochi, Abia State, Nigeria was carried out in order to determine the concentration of heavy metals in quarry soil and their bioaccumulation in cassava tuber (Manihot esculentum). Soil samples were collect...

Bioaccumulation of Some Heavy Metals in Tissues of The African Cat-Fish Clarias gariepinus From Selected Markets in Delta State, Nigeria

ABSTRACT The increasing rate of consumption of the common African catfish, Clarias gariepinus, a popular delicacy in Delta State, Nigeria has raised worries about the safety of health of consumers in the face of perceived increasing input of recalcitrant pollutants such as the heavy metals in the aquatic habitats of the organism. This research therefore investigated the bioaccumulation of some heavy metals (Pb, Cd, Cu, Zn, Co) in the muscle and brain tissues of the catfish, C. gariepinu...
