Estimating a watershed's frequency of infiltration and runoff as well as its other hydrological characteristics is also helpful. The study was conducted using Geographical Information System (GIS) techniques with the aim of establishing relationship between surface morphometry, underlying geology and groundwater recharge. For detailed measurement and analysis, Digital Elevation Model (DEM) and high resolution imageries were employed for basin delineation, slope characterization, channel network extraction and stream ordering in order to derive the linear, areal, and relief aspects of morphometric parameters. The findings showed that a total number of 116 streams joined the 4th order stream in which 83 streams were 1st order, 25 streams were 2nd order, 7 streams were 3rd order and the major trunk was 4th order stream, occupied an area of 1486.86km2. The stream network's drainage system exhibits dendritic design. The results further indicate that the values for stream frequency, infiltration number, drainage density, drainage texture, length of overland flow, elongation ratio and basin relief are 0.08, 0.032, 0.41km/km2, 0.023, 1.22km, 0.54 and 28.59m respectively. The observed values of both linear, areal and relief parameters were generally low. Low values for the areal and relief criteria indicates that the sub-basin is at its youthful stage of development and possesses very good permeable subsurface formation and prospect with the possibility of high potential groundwater resources. The result help us understand the connections between hydrological variables and geomorphological parameters as guidance and/or decision-making instruments for the authorities to develop decisions for the environmentally friendly growth of the basin, water supply planning, water budgeting, and disaster mitigation within the Hadejia river sub-basin.","PeriodicalId":404388,"journal":{"name":"African Journal of Environment and Natural Science Research","volume":"79 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141642949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The project area lies within latitudes 6°50'4.0''N – 6°57'52.0\"N and longitudes 7°21'6.3\"E – 7°28'12.0\"E, and covers an area of about 89.6 km2. Vertical Electrical Soundings (VES) were carried out with a digital read out resistivity meter (ABEM SAS 1000). The VES points were marked at 25 m and 75 m along a 100 m line. A total of eight soundings were carried out in the area. The VES data collected were interpreted using INTERPEX software and the results presented in terms of resistivity, thickness, depth and lithology. The lithology was inferred by correlating the result to the lithology log of the borehole drilled in the hotel and the geology of the study area. The VES result shows lithologic layers varying from 4 to 5. Aquiferous sand and Aquiferous sandy shale constitute the aquifer units in the area at depth of 30.26 m to 188.20 m, with their thickness ranging from 30 m to 74 m as shown by their isopach map. The aquifer protective capacity was determined by calculating for longitudinal conductance and matching the values to known standards. The calculated longitudinal conductance varies from 0.0409 to 3.1235 mhos. The interpreted VES results reveal poor, moderate, good and very good aquifer protective capacities of the overburden layers.","PeriodicalId":404388,"journal":{"name":"African Journal of Environment and Natural Science Research","volume":"30 39","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141645691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Similarly, lithium extraction depletes and contaminates water, exacerbating water scarcity and health issues. Hazardous by-products from lithium mining, such as heavy metals and toxic chemicals, often cause air pollution, environmental degradation, and severe respiratory and systemic health problems. To prevent a repeat of the catastrophic outcomes seen in the Niger Delta, stringent environmental regulations, comprehensive impact assessments, and community involvement are imperative. Establishing a specialized regulatory body and adopting best practices from established lithium mining countries can ensure the sustainable and safe exploitation of lithium resources.","PeriodicalId":404388,"journal":{"name":"African Journal of Environment and Natural Science Research","volume":"14 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141654188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study involved a seasonal survey of bacterial species and their bioremediation potentials in leachate from the Ikueniro open solid waste dumpsite situated in Uhunmwode Local Government Area, Edo State, Nigeria. Bacterial isolation and enumeration of the leachate samples was carried out using pour plate technique. Phenotypic techniques and 16S rRNA gene analysis identified the bacterial isolates. The bacterial mastermix for bioremediation of the leachate consisted of a consortium of bacterial strains isolated from leachate discharging from the Ikhueniro dumpsite. The bioremediation efficiency of the leachate was deduced by measurement of heavy metals and other chemical analytes using standard methods prescribed by the American Public Health Association. The bacterial species isolated from Ikueniro dumpsite such as Bacillus licheniformis strain EGBON & OKORIE 103 and Klebsiella aerogenes strain EGBON & OKORIE 108 were deposited in the United States NCBI GenBank. A consortium of these bacterial strains served as inocula for the bioremediation setup. A huge removal of ammonia from the leachate was observed during the 28-day bioremediation experiment, amounting to a mean bioremediation efficiency of 80.65%. The removal of the heavy metals from the raw leachate by the bacterial mastermix in increasing order was as follows: nickel<copper<zinc<lead<iron<cadmium<arsenic<mercury. Bioremediation of the leachate using indigenous bacteria promises to be an effective tool for management of toxicants from leachates of open solid waste dumpsites.","PeriodicalId":404388,"journal":{"name":"African Journal of Environment and Natural Science Research","volume":"23 S2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141702723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used a static toxicity bioassay to examine the interaction between heavy metals (Pb and Cr) and organophosphorus herbicides (analytical grade glyphosate, commercially formulated - Roundup and Forceup) on African catfish (Clarias gariepinus BURCHELL 1822). Lethal concentrations (LC50) for roundup (RU), forceup (FU), analytical grade glyphosate (AGG), chromium (Cr), and lead (Pb) were 17.23 mg/l, 4877 mg/l, 131.12 mg/l, 21.16 mg/l, and 74.82 mg/l respectively. In addition, fish exposed to varying concentration of chromium (5.0 mg/l and 7.5 mg/l) and lead (20 mg/l and 25 mg/l) with glyphosate (RU: 10 mg/l; FU: 4300 mg/l; and AGG: 100 mg/l) for 96 hours were examined for biochemical parameters. Blood plasma examined for liver and kidney profile indices showed that kidney functions’ parameters (protein, albumin, AST-aspartate aminotransferase, ALT-alanine aminotransferase and Bilirubin) and liver functions parameters (urea and creatinine) increased significantly (p<0.05) when glyphosates combined with lead and chromium treated groups compared with the control group. This study therefore, showed that low concentrations of combined toxicants of glyphosates and heavy metals (Cr and Pb) will synergistically induce deleterious effects on the liver and kidney of Clarias gariepinus.","PeriodicalId":404388,"journal":{"name":"African Journal of Environment and Natural Science Research","volume":"12 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141335107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary data sources of this study were from stakeholders of land administration via questionnaire administration as well as data gathered from scheduled interviews to sample the opinion of staff of the Abuja Geographic Information Systems (AGIS), the agency in charge of Land Administration in the Abuja, to determine the overall system of e-LA in the FCT, management of e-LA activities and the operations as well as knowing if the organizations saddled with the responsibility of e-LA have the required number of staff. It recognizes the need for individual workers to function properly through education and training programs and determine the overall vision, efficiency of their implementation of e-LA and the performance of the system in meeting the challenge of e-LA. The result of the SWOT matrix of Abuja Geographic Information System revealed Weaknesses of Abuja Geographic Information System (AGIS) greater than its Strengths. Threats were greater than Opportunities, so it is easy to conclude that Abuja Geographic Information System (AGIS) has not managed e-LA in the FCT effectively and efficiently but it has managed to survive and cope with the management.

In West Africa, the manufacturing and processing of palm oil are done without proper hygienic monitoring; it is therefore almost impossible to detect fraud in the system. A major disadvantage associated with the use of adulterants in palm oil is that the adulterants have not undergone adequate research and the degree of health hazards they can pose to humans when consumed. This study was designed to evaluate the toxic effects of Azo dye adulterated palm oil on kidney function and Lipid profile in albino rats exposed to Azo-dye adulterated palm oil. Twenty-five albino rats were divided into five groups and treated as thus: Group I (control), Groups II and III were treated with only 1 ml/kg of unadulterated and adulterated palm oil respectively, while Groups IV and V were treated with only 50 mg/kg of Sudan III and IV dyes respectively for 28 days. Renal function tests, and lipid profiles were determined using analytical test kits. Data obtained were statistically analyzed with one-way analysis of variance (ANOVA) followed by tukey test using Graph Pad prism 9.0.0. The results were presented as mean ± standard error of mean (SEM). Differences between means of treated and control groups values at P ≤ 0.05 at 95% confidence interval were considered significant. The results showed a significant increase (p < 0.05) in creatinine, urea concentrations, Sodium ion (Na+) and Potassium ion (K+) in groups treated with adulterated palm oil, Sudan III, Sudan IV (groups III, IV and V respectively) when compared with control groups. A significant increase (p < 0.05) in low density lipoprotein (LDL), cholesterol, very low-density lipoprotein (VLDL) and Triacylglycerol (TAG) was observed in treated groups when compared with control groups while a significant decrease (p < 0.05) in high density lipoprotein level (HDL) observed in treated groups when compared with the control group.
