    Abstract: This paper presents soil quality as affected by dumped municipal solid waste. Landfill leachate was collected from a hole dug 10 m away from the waste dump site for laboratory analysis. Soil samples were also collected from four trial pits in the dumpsites at the depth of 0.3, 0.6 and 0.9 m and at a distance of 10, 20, 30 m and the control 100 m away from the dumping site. The collected soil samples were subjected to physiochemical and geotechnical analysis. This includes particle size distribution, pH, EC, total organic carbon, total organic matter, extractable micronutrients and heavy metals (Zn, Cu, Mn, Fe, Pb, Cd, Cr, Cl and Ni), Attterberg limits, specific gravity and hydraulic conductivity. The physicochemical concentration was then compared with the maximum allowable concentrations of chemical constituents in uncontaminated soil. The Laboratory analysis shows high value of pH (8.51) DO (0.17 mg/l), COD (68mg/l), BOD5 (324 mg/l), Pb (0.31 mg/l) and Cd (0.06 mg/l) in the leachate sample. The physical properties of the soil near the dumpsite indicated that the soil belongs to sandy loam in texture. pH (6.3-8.32), Electrical conductivity (241-2018 s/cm), total organic carbon (0.24-2.16 ) and total organic matter (0.41-3.73%) were higher near the vicinity of the dumpsite and decreased with increase in the depth and distance. Extractable micro nutrient and heavy metal concentration (Zn, Cu, Mn, Fe, Pb, Cd, Cr, Cl and Ni) were also found to be high near the dumpsite and decreased along the soil depth and distance from the dumping site. The variance in the geotechnical properties of soil revealed by the test results was impacted by the dumped municipal solid waste. These effects decrease with increase in depth. These findings will help in facilitating the invention and introduction of site specific technologies.

    Abstract: This paper presents potential impact on health of emission from landfill site on Uyo village road, Uyo local government area of Akwa Ibom State, Nigeria. Three sampling points were assessed for particulate matter (PM2.5 and PM10), nitrogen dioxide (NO2), sulphur dioxide (SO2), carbon monoxide (CO), hydrogen sulphide H2S, ammonia (NH3), total volatile organic carbon (TVOC) and hydrogen cyanide (HCN) using highly sensitive digital portable meters. The data obtained were expressed in terms of an air quality index. Air quality index indicates that the ambient air can be described as unhealthy for sensitive groups for NO2, unhealthy for SO2 and PM2.5 and moderate for CO, respectively. H2S, NH3, TVOC, HCN, PM10 were not indicated in USEPA air quality standards. It recommended that stringent and proper landfill emissions management together with appropriate burning of wastes should be considered in the study area to ease the risks associated with these pollutants on public health.

    Abstract: This paper presents the composition of municipal solid waste in Uyo and vector-borne diseases associated with municipal solid waste within the vicinity of the dumping site (less than 1 km) and controlled site (above 1 km). The compositions of municipal solid waste were determined using samples obtained from Uyo village road waste dumping site. The dumpsite receives solid waste from all the communities in Uyo local government area. In order to assess the public perception of vector-borne diseases associated with municipal solid waste, sample survey method was adopted, which involved the administration of 500 questionnaires of which 250 were administered to the residents who lived less than 1 km from the boundary of the waste dumpsite and 250 questionnaires were also administered to the communities living further away. The compositions and percentages constituent by mass revealed the following: Organic waste component constitute 53.86% and inorganic constituted a waste portion of 46.14%. For vector-borne diseases associated with municipal solid waste, the results indicated that 70.8% of the respondents attended tertiary education (OND/NCE and above), so the issues associated with municipal solid waste may not be strange to them. A significant number of respondents are aware that the origin of municipal solid waste is residential, commercial, industrial, market, street sweeping and industrial sectors. Respondents are more aware that rats, flies, mosquitoes, birds, pigs and cockroaches are vector-borne diseases associated with municipal solid waste. The findings in this study will be useful in a comprehensive solid waste management program which encompasses sweeping, storage, collection and disposal of solid waste. However, the waste can be best treated if any of these techniques are utilized composting, gasification and energy recovery in future for further reduction of waste.

    Abstract: Internal migration is defined as “a movement of people from one area of a country (especially one local government area) to another area of the same country for the purpose or with the effect of establishing a new residence” either temporarily or permanently, is a complex and multidimensional process. In this study we are expected to determine the impact of internal migration in Port Harcourt city and Bori town respectively and to show the effect of the variation of some parameters that affect the growth of Port Harcourt city, through Simplified Assumptions and Mathematical Formulations. The internal migration of effective working population from Port Harcourt city to Bori town is lesser than that of Bori town to Port Harcourt city due to lesser jobs and social infrastructural facilities in Bori than Port Harcourt. Method of Analysis used is a non-linear ordinary differential equation of order 45 which otherwise is called O.D.E 45(Matlab ODE 45). It is evident from the results of the study that the variation of the rate of internal migration can produce either a positive or a negative effect on the population growth patterns of the two interacting population predictions.

    Abstract: Port Harcourt municipality, southern Nigeria, is faced with environmental problems with slums and informal settlements communities, ranging from use of poor and overstressed facilities and inadequate water and electricity supplies and lack appropriate garbage disposal facilities and good drainage systems resulting in perennial flooding due to blocked drainage systems resulting in a number of diseases, such as malaria, diarrhea, cold and cough. Communities are densely populated, with more than five people living in a room. Therefore this study was carried out to assess the public health status of slums/ informal settlements in Port Harcourt Municipality in Rivers state. The study utilized a mixed-method approach. A cross-sectional survey questionnaire and in-depth interview were used to collect data. A total of 180 Questionnaires were distributed across the  five (5) selected waterfronts communities in the survey and key informants were interviewed to obtain detailed information about the status of the various communities in the Informal settlements studied. The results of the study revealed that the most prevalent illnesses in all Slums/Informal Settlements were malaria, typhoid, dysentery, diarrhea, coughing, worm infestation, and skin infection. The prevalence rate of infectious disease recorded for all slums/Informal settlements show that Malaria had 15-17%; Typhoid fever14-16%, Diarrhea 11-13%, Dysentery 12-14%, Cough 5-10%, Worm infestation 8-11% and Skin infections 2-4%.  However, Malaria remains the foremost killer disease in Nigeria. It accounts for over 25% of under 5 mortality, 30% childhood mortality and 11% maternal mortality. These results suggest that people living in slums are predisposed to severe outbreak of epidemics, therefore requires an urgent attention for comprehensive interventions from the government and other organizations to strengthen existing programs to improve the public health and quality of life of this vulnerable population.

    Abstract: The present investigation discusses the characteristic of leachate generated from municipal solid waste landfill and it adverse impacts on downstream water quality. Landfill leachate was collected from a hole dug 10 m away from the waste dump site and the appearance of the leachate sample looks black. Three downstream water samples were collected at 10 meters intervals each from each other and less than 100 meters from the boundary of the dumpsite. All the samples were examined for temperature, pH, TDS, TSS, BOD, COD, nitrate, ammonia, Cu, Ni, Pb, Cd, Cl, total phosphate, sulfate, EC, DO and turbidity. The aim was to compare physicochemical and heavy metal properties of leachate and downstream water quality with internationally accepted protocols. The Laboratory analysis exhibited prevalence of high value of pH (8.5130.09), temperature(29.00.0), turbidity (14.00.41NTU), DO (0.1670.05 mg/l), COD (68.00.33 mg/l), BOD5 (324.03.00 mg/l), EC (446315.53s/cm), Total phosphate (62.3580.01 mg/l), Pb (0.310.00 mg/l), Cd (0.060.00 mg/l), Ni (0.3550.01 mg/l), and Cu (8.670.04 mg/l) in the leachate sample, which have exceeded their permissible limits. For downstream water samples, pH (7.760.07 to 7.5070.09), temperature (29.00.00) for the three sampling points, DO (3.6670.15 to 3.2330.12 mg/l), total phosphate (8.2250.00 to 7.9350.02 mg/l), Pb (0.4650.01 to 0.0910.00 mg/l), Cd (0.040.00 to 0.0230.00 mg/l), Ni and Cu (0.0430.06 mg/l) and (1.0620.00 mg/l) respectively, also exceeded their respective permissible limit recommended by Nigerian Standard for Drinking Water Quality, World Health Organization in drinking water quality. From this study, there is evidence that there is an increase in risk to surface water that is reported near Uyo village road municipal solid waste dumping site. Therefore, the concerned authority should take appropriate intervention measures to protect surface water. Also, knowledge of leachate quality will be useful in planning and providing remedial measures to protect downstream water quality in the area.

    Abstract: The present work aims at assessing the hazard quotient (HQ) in the groundwater samples collected around Uyo main refuse dumpsite. For calculating the HQ, 17 parameters, namely, temperature, pH, TDS, TSS, BOD, COD, nitrate, Cu, Ni, Pb, Cd, Cl, total phosphate, sulfate, EC, DO and turbidity were considered. The HQ for pH (1.0 – 1.1), temperature (1.2), TDS (0.0), TSS (0.4 – 0.5), BOD (0.5 – 1.0), COD (0.1), nitrate (0.0 – 0.6), Cu (0.7 – 0.8), Ni (0.2), Pb (5 – 16), Cd (3.0 – 10), Cl (0.3 – 0.4), phosphate (1.4 – 1.9), sulfate (0.0), EC (0.1), DO (1.6 – 1.9) and turbidity (0.2). The HQ of temperature, pH, DO, phosphate, Pb, and Cd in water samples were all greater than unity and thus posed a potential health risk for human oral consumption. The present study revealed that groundwater around Uyo village road waste dumpsite poses a health risk to groundwater resource users due to groundwater contamination by the leachate. Monitoring of this site is recommended as well as research by biomedical experts to reveal the rigorous adverse impacts that physio-chemical, and heavy metal contamination of groundwater might induce in humans, particularly among individuals in vulnerable populations. Also, the local authorities should be made aware of such health risks and provide potable water facilities either by treating the water or find alternative sources for drinking.

    Abstract: his study investigated potential of the use of Drill Cuttings Ash (DCA) in the stabilisation of Niger Delta soils for road construction. Most of the in-situ soils encountered in the region are fine-grained and highly plastic that would require special treatment. Four soil samples were obtained and the following tests were carried out: classification, compaction, California Bearing Ratio (CBR), and Unconfined Compressive strength (UCS). Dry DCA quantities ranging 2 – 8 percentages by weight of the soil was added to the air-dried soils for the stabilisation process. They were classified as A-6 (clayey soil), A-2-6 (clayey sand), A-3 (silty fine sand), and A-4 (silty clay soil). Generically, the unstabilised soils were fine-grained having low to medium plasticity, with low shear strength. Other results showed that 6% DCA content caused improvement in the texture, plasticity, and dry density of the clayey soil, while its CBR and UCS parameters compared favourably well with the unstabilised soil values. Also, there was increase in CBR value of the clayey soil after soaking for 24 hours. DCA increased the plasticity of the clayey sand, silty fine sand, and silty clay soil, and there was no substantial improvement in their strength properties. These results showed that DCA would be useful in improving clayey soilswhich are known to be prone to excessive swelling and difficult to handle during construction especially after heavy rainfall.
