| 1 | Integrated Geophysical and Hydrogeochemical Characterization and Assessment of Groundwater Studies in Adum West Area of Benue State,Nigeria显示文摘Integration of geophysical and hydrogeochemical methods has been scientifically proven to be useful in vulnerability study and groundwater characterization.Subsurface geoelectric parameters such as resistivity and thickness obtained from geophysical method(Vertical Electrical Sounding VES)was used to determine aquifers vulnerability,longitudinal resistance(ρL)and transverse unit resistance(Rt).Thirty four water samples were collected from groundwater sources for physicochemical analysis.Estimated results from longitudinal conductance(S),(Rt)and(ρL)showed that the values ranges from 0.03 to 2.5mhos,103.64 to 1964417.8Ω/m^(2) and 215.41 to 65731.68Ω-m respectively.Result from S suggested that 50%of groundwater is considered to be vulnerable to contamination from the earth surface,while the remaining 50%is considered to be slightly vulnerable to surface contamination.Further findings obtained from hydrogeochemical analysis such as Gibb’s and Chadba plots revealed that groundwater is highly influenced by rock water interaction,groundwater is classified to be Na^(+)+HCO_(3)^(-),Ca^(2+)+Mg^(2+)+HCO_(3)^(-),Na^(+)+Cl^(-)and Ca^(2+)+Mg^(2+)+Cl^(-)water type.Deduction from Soltan classification suggested that groundwater is classified to be of Na^(+)+HCO_(3)^(-) and Na^(+)-SO_(4)^(2-) water type.Results obtained from Ec and pH suggested that the values were below WHO permissible limit,while result obtained from TDS showed that at some sampling points TDS values were above WHO limit.Based on pH value obtained groundwater within the study area fell within slightly basic to acidic. | Moses Oghenenyoreme Eyankware Christopher Ogwah Umayah Otitie Star | 2021 | Journal of Geological Research2021，3，3： | 2 |
| 2 | A Synoptic Review of Mineralogical and Chemical Characteristics of Clays in the Southern Part of Nigeria显示文摘This paper reviews the mineralogical and chemical characteristics of clays found in southern part of Nigeria,with a view to determine its usability.The usability of clays,depends on its chemical and mineralogical charactertics,the end product of clay after it is been processed is also based on it’s charactertics.From reviewed literature,it was observed that sampled clay within the study area were analyzed using the XRD,XRF and ICP-MS method.Further findings also revealed that the dominant clay minerals within the study area include montmorillonite,illite,and kaolinite.On the other hand,it was observed that non-clay minerals such as feldspar,quartz,dickite and many others were found with clay as revealed by several scholars.While chemical charactertics of clay consists mainly of Al2O3,K2O,CaO and SiO2,with other major oxides such as P2O5,MgO,Fe2O3,TiO2,MnO and Na2O.Some trace elements such Be,Ba,Sc,Sr,Zr,V and Y were reported to be present in clays deposit found in selected part of Ogun state.From reviewed articles,it was observed that mineralogical and chemical charactertics of clay make it suitable for pharmaceutical,textile,cosmetic and polymer industries,but considered to be fairly suitable for oil and gas industry. | Moses Oghenenyoreme Eyankware Christopher Ogwah Joy Chiaka Ike | 2021 | Research in Ecology2021，3，2： | 0 |
| 3 | Impact of Past Mining Activities on Water Resources Around Active and Abandoned Mines and Quarries in Ebonyi State,South-Eastern Nigeria-A Mini Review显示文摘This paper presents a review on previous activities of mining on water resources around active and abandoned mines/quarries across Ebonyi State,South-Eastern,Nigeria.As high demand for water increases due to population growth and rapid development across the state,it is of upmost importance to periodically review water quality and also monitor water resources.However,less information is available on evaluation of impact on mining activities on water resources.For the purpose of this research,related articles were downloaded from Google,published article on effect of mining on water resources was download and thoroughly studied to evaluate effect of mining on water resources of the study area.Findings revealed that past mining activities has lead to chains of complex chemical reactions that has altered the quality of water resources. | Moses Oghenenyoreme Eyankware Nnabo Paulinus Nwankwo Christopher Ogwah | 2020 | Hydro Science & Marine Engineering2020，2，2： | 0 |
| 4 | Achieving Sustainable Use and Management of Water Resources for Irrigation in Nigeria显示文摘Water resource is available in Nigeria to meet water demand for domestic,agricultural and industrial use.If well enhanced and protected from various source of pollution.However,less information is available on suitability of water resources for irrigation use in Nigeria.This article reviews literature of the past with regards to influence of geogenic and anthropogenic activities on water resource for irrigation purpose in Nigeria and also to explain the current state of suitability of water resource for irrigation studies in Nigeria and gaps in studies.It also summarizes future ways on water resource management and preventive measure for water resource pollution for irrigation use.Related articles were downloaded from Google scholar in water-related issues.This paper tends to review previous article on water resource in Nigeria,and its suitability for irrigation.The primary aim of this paper is to produce a synoptic overview of the water resources in Nigeria and its suitability for irrigation use.From paper reviewed it was observed that 89%of water resources was considered suitable for irrigation. | Moses Oghenenyoreme Eyankware Ezekiel Obinna Igwe Christopher Ogwah Ruth Oghenerukevwe Eyankware Ulakpa | 2020 | Journal of Environmental & Earth Sciences2020，2，2： | 0 |
