Effects of Gas Flaring on Cassava Crop at Aggah-Egbema in Ogba/Egbema/Ndoni Local Government Area of Rivers State

ABSTRACT The current research investigated the bioavailability of gas flare pollutant fallouts in crop tissues via the soil repository matrix around the Aggah-Egbema Oil Flow Station in Ogba/Egbema/Ndoni Local Government Area of Rivers State. Three sampling locations were established at 1, 2 and 10 km from the gas flare stack. Ambient air quality for SOx, NOx, COx, H2S, suspended particulate matter (SPM10), petroleum hydrocarbons, and trace metals (...

ABSTRACT The water quality of the Imo River in Oyigbo local government area was ascertained using standard methods in this research. The important physicochemical characteristics of the river were investigated during the wet season of 2013 at six sampling locations. In situ measurements were made for water temperature, salinity, turbidity, dissolved oxygen (DO), biological oxygen demand (BOD), etc using the HORIBA U-10 water qualit...

Assessing the Performance of Anthocleista Dialonensis and Viscum Album a Eco-friendly Corrosion Inhibitors in Acidic and Saline Environment

ABSTRACT Leaf extract of Anthocleista djalonensis and Viscum album were investigate as inexpensive and environmentally friendly corrosion inhibitors for mild steel in 0.5 M H2SO4 and 3.5% NaCl was investigated by weight loss and potentiodynamic polarization techniques. The results revealed that Anthocleista djalonensis and Viscum album inhibited the corrosion reaction and the inhibition efficiency increased with increasing concentration of extract...

Variation in Groundwater Qaulity Parameters in the Vicinity of a Waste Dumpsite in Eneka, Rivers State, Nigeria

ABSTRACT The quality of groundwater impacted by a waste dumpsite in Eneka, Rivers State was studied using temporal approach. Groundwater samples were collected and analyzed for 27 parameters using standard methods. Water samples were collected with 250mL plastic containers from seven sampling boreholes. Samples for heavy metals were fixed with concentrated HNO3 in the ratio of 2:500. The descriptive statistics, one-way ANOVA, ...

Assessment of Trace Metal Contamination of Selected Fish Species From Choba and Aluu Axis of New-Calabar River, Rivers State, Nigeria

ABSTRACT This study investigated the trace metal contamination of two fish speciesClariasgariepinusandOreochromisniloticus obtained from the Choba axis (Downstream) and Aluu axis (Upstream) of New Calabar River in Rivers State. The fishes were dried, ashed and analysed for trace metals such as Zn, Pb, Cd and Cu using the atomic absorption spectrophotometer of model Unican Solar 969.The results obtained showed that Pb values ranged from 0.097 to 0.6...

Assessment of Borehole Water Quality, Potential Sources of Pollution and Prevalence of Water Related Diseases in Umuogonnama Community, Obio Akpor Local Government Area of Rivers State

ABSTRACT This study involved proximate analyses of four borehole water samples within an average distance of 30.25m from municipal solid waste dumpsites in Obio-Akpor Local Government Area of Rivers State, an area commonly known as Greater Port Harcourt or Port Harcourt Metropolis. Water quality and analyses of some bio-physico-chemical variables (pH, total suspended solids (TSS), total dissolved solids (TDS), colour, total coliform, faecal coliform...

Effects of Devegetation on Agricultural Soil Quality at Nnewi North Local Government Area of South Eastern Nigeria

ABSTRACT This study evaluated the Impact of Devegetation on Soil environment of Nnewi North LGA in South East- Nigeria. It is caused by increasing demand for land with its consequences on disruption of soil ecology, climate change, breakdown of nutrient cycle and increase in soil erosion, siltation of dams and reservoirs, destruction of wildlife habitats, and loss of plant and genetic diversity. Soil samples for analysis were obtained in the study ...

Conversion of Agricultural Wastes into Poultry Feed for Sustainable Environment

ABSTRACT Agricultural waste has been of major source of environmental pollution and its utilization and conversion to renewable energy will discourage possible consequences associated with its discharge in the environment. This study was targeted at the conversion of waste to fish feed. Samples were collected in quantities from dumpsites abattoirs, market places using 20kg polypropylene bags and transported to the production sites. Pla...

An Investigation into the Nature and Variability of Climate Change Induced Rainfall Over Awka, Anambra State

ABSTRACT This thesis investigates the nature and variability of climate change-induced rainfall over Awka, Anambra state. Time series of annual rainfall for Awka, Anambra state was analysed to reveal shifts in rainfall pattern occasioned by ongoing climate change. Past rainfall data over four decades (1975-2014) were collected for the study area for analysis. The series exhibited shifts in bimodal rainfall pattern during annual analysis, however, ...

Evaluation of Remediated Oil Impacted Soil at Kpean and Buan Communities, Ogoni, Rivers State

ABSTRACT This study was carried to assess the effectiveness of clean-up sites impacted by oil spill at Kpean and Buan communities in Khana Local Government Area of Rivers State. Soil samples were collected at 0-15 and 15-39cm depths from three sampling sites(two impacted and one control sites) with soil auger and analyzed for pH, TOC, TPH, Zn, Cd, Cd, HB and HDB using standard methods. The concentrations of pH, TOC, TPH varied between 5.08 – 6.86 (6.04 + 0.24)...

Assessment of Physico-Chemical Quality of Nworie River in Owerri Metropolis

ABSTRACT Pollution of rivers, had become a major problem facing our society today. This often occurs as a result of waste washed into Rivers as in the case with Nworie River in Owerri metropolis. In order to assess the water quality of Nworie River, water samples were collected at three locations namely point A (upstream) serves as control, point B (midstream) and point C(downstream). The samples were properly analyzed with focus on some physical ...

Groundwater Quality Assessment of FUTO and Neighbouring Communities

ABSTRACT This study examined the physicochemical and bacteriological analysis of ground water quality in Federal University of Technology, Owerri (FUTO) and its neigbouring Communities. Groundwater samples were collected, two from 4 different locations and were immediately transported to the laboratory for standard analyses. pH ranged between 5.24-4.71; EC (40-11.00 μS/cm); sulphate (5.94-1.58mg/L); Total Hardness (44.30-12.40mg/L); Mg (8.79- 1.2...
