Abstract: Disposal of wastes into the landfills may constitutes health risk and environmental contamination due to landfill gas and leachate production from components of wastes, the dangers of possible deleterious effects on the residents around the landfills has not been adequately evaluated. This study attempts to determine the effects of Port Harcourt (Eliozu) landfill leachates on some oxidative stress markers in Wistar rats. 25 Wistar rats weighing between 180g and 250g were divided into five groups of 5 animals each. Groups are as follows: Group 1: received 1ml of table water, Group 2: recieved borehole water, Group 3: received 10% of leachate concentrations, Groups 4 and 5: received 50% and 100% of leachate concentrations every 24 hours for 90 consecutive days. On day 91, blood samples were collected for oxidative stress markers analysis. The results of serum and renal oxidative stress markers show a significant (p<0.001) increase in all experimental groups when compared with control groups: indicating a possible deleterious impact of the leachate on experimental animals..

Abstract: It is a common knowledge that environmental impact and the influence of location externalities are vital to the formation of residential property value. Factors related to location and the environment that positively or negatively impact on residential values include; age of the building, electricity, water supply, size of the rooms/kitchen, number of bathrooms/kitchens, noise pollution, air pollution/quality, storm water/Flooding. Similarly, attributes of residential location such as the proximity to school, workplace, shops/market, hospital, airport, parks and playgrounds, quality of neighbouring structures, accessibility to public transport and sporting facilities, road quality/network traffic volume, transportation etc. are among key factors that determine residential values. The objective of this research is to perform a scholarly review of empirical literature on theenvironmental.....

Abstract: Levels of air pollutants from Eleme Refinery in River State, Nigeria were assessed. The main objective was to determine the concentration of selected air pollutants in the refinery and some communities around the refinery. Particulate matter (PM10) was measured with AEROCET Mass particle counter/dust monitor. The values generated by this exercise were used in Gaussian model to compute the concentrations of the pollutants in Eleme, Agbonchia, Nchia, Aleso, Aleto and Alode communities. Field measurements of the pollutants were also carried out in these areas. Geographic Information System (GIS) was used to estimate the distance between the communities and the refinery while Arc GIS9.3 version software was applied in producing concentration raster of the pollutants. Comparisons were made of data generated with WHO standards. Results obtained from Gaussian Model.....

Abstract: This study evaluated the use of information system in vegetation pattern, tree species abundance, and tree species diversity within the Forestry Research Institute of Nigeria (FRIN), Onne, Rivers State, Nigeria. Tree management requires information on the growing stock, distribution pattern and diversity. Such relevant information will guide managers in proper appraisal and proficient exploitation of the forest resources. All trees within the sampled plots were measured using modern inventory methods. The measurements obtained were grouped into species, diameter at breast height; height classes and their basal area estimates computed. Global Positioning System (GPS) was used to record the coordinates of individual trees, with their points recognized on the imagery for the geo-referencing of the satellite imagery and imported into ArcGIS 10.5 for further geo-processing analyses. Trees within......

Abstract: This study is aimed at establishing the relationship between growth diameter and photosynthetic variables of Azadirachta indica used as an avenue tree in Abuja Park, University of Port Harcourt. Two sources of data were used for the study which included photosynthetic variables such as photo intensity, relative humidity and temperature as well as the diameter growth variables namely Diameter at breast height (dbh), Tree Total Height (THT) and Crown Diameter (CD), while Crown Spread Ratio (CSR), Linear Crown Index (LCI) and Crown Projection Area (CPA) estimated indirectly from 208 standing Azadirachta indica trees planted as avenue trees along Abuja Road, University Park, University of Port Harcourt. The data obtained from photosynthetic variables and diameter growth variables from the study area were analyzed using descriptive, correlation and regression.....

Abstract: This study aims to remove hazardous gases, sulfur dioxide (SO2), and hydrogen chloride (HCl) emitted from small- to medium-size incinerators using a dry reaction technology. Actual flue gas from the waste incinerator Unit #1 of company B is applied to design a dry reactor to be installed on the rear of SDR. Two types of highly reactive slaked lime with different physical properties are used to identify and check their acid gas removal efficiency and performance and to propose optimal operation conditions. The result indicates that a dry process outweighs the current semidry one in efficiency for both cost and acid gas removal. When the same condition for operation is given, the highly reactive slaked lime, which has a larger specific surface area and pore volume, shows higher acid gas removal efficiency while contributing to the elimination of dioxins

Abstract: Background: Abattoir activities are associated with some environmental risks. The untreated effluent when discharged to the surface water exposes the people to some water related illnesses. This study assessed the health risks of people dependent on abattoir polluted stream water for some domestic uses. Materials and Methods: One hundred households in the study area were randomly sampled to ascertain the uses of the stream water. Hospital record was used to show the prevalence of some water borne diseases. Abattoir effluent from the two abattoirs were tested in the laboratory to determine their physico-chemical and microbiological constituents before discharge to the stream likewise water samples collected at the point of abstraction. Both abattoir.....

Abstract: The bacteriological quality of Ajumoda stream and reservoir in Iseyin Local Government, Oyo State, Nigeria was carried out to ascertain the quality of the water. Water samples were collected randomly from three different points of the stream for four weeks. Water samples were collected once in a week in the morning between 8:00am-10:00am for 4weeks. The bacteriological assessment was examined using the basic microbiological techniques. The total heterotrophic bacteria count, total coliform count and faecal coliform count were used to determine the bacterial contamination. Biochemical tests and gram reaction were used to identify the bacterial isolates. The mean total heterotrophic count, total coliform count and faecal coliform count across stations.....

Abstract: This study examines the relationship between the different morphometric parameters and characters of the drainage terrain. To do that, Omi dam basin in Bauchi state, Nigeria drainage characteristics was delineated using Shuttle Radar Topographic Mission (SRTM) data. The Aspect, Drainage, and Slope maps were prepared using ArcGIS 10.2.1 software. The Omi Dam is fourth-order stream that exhibits dendritic pattern. The trails drainage patterns are also observed in some areas of the basin, which may be due to the effect of regional tectonics. The mean bifurcation ratio is 1.6 showing normal basin which is somehow controlled by structural disturbances. Drainage density (0.3) shows very coarse drainage texture also having positive correlation with stream frequency. The elongation ratio is 0.33 along with circulatory ratio (0.31) shows elongated nature of the basin. The low values of drainage density and stream frequency imply that surface run-off is not quickly removed from the basin, making it liable to slight flooding..
