Oxides And Heavy Metals Concentration Around A Cement Plant At Yandev, Central Nigeria, Fanan Ujoh Ph.D, Muhammad Mamman Alhassan Ph.D
Oxides And Heavy Metals Concentration Around A Cement Plant At Yandev, Central Nigeria, Fanan Ujoh Ph.D, Muhammad Mamman Alhassan Ph.D
Dr. Fanan Ujoh
Aims: To determine the level of concentration of oxides (chemicals) and heavy metals in 6 soil samples. To further compare the results with acceptable soil quality standards to ascertain the status of soil quality within the study area. Study Design: Collection and analyses of soil samples from the vicinity of Dangote Cement factory, Yandev. Place and Duration of Study: A total of 6 soil samples were collected: using a 2-kilometer interval, five samples were collected within the study area starting from the center of the Cement factory while the sixth soil sample was collected from a Control Community (Tarhembe) located …

Limestone mining and cement production at Yandev, Nigeria commenced in 1980 without an environmental impact assessment (EIA) to ascertain the extent of impact these activities could bring to bear on the physical and living conditions of the host environment. This study was carried out to assess the impact that mining of limestone and production of cement has inflicted on the quality and density of vegetation within the study area about 32 years since production commenced. Multi-temporal satellite imageries of the study area (Landsat for 1976, 1986, 1996 and Nigeriasat-1 for 2006), ILWIS Academia 3.3 and SPSS Version 15 were used …
Arsenic Removal From Soil With High Iron Content Using A Natural Surfactant And Phosphate, Soumyadeep Mukhopadhyay Dr, Mohd Ali Hashim Dr, Matthew Allen Mr, Bhaskar Sen Gupta Dr
Arsenic Removal From Soil With High Iron Content Using A Natural Surfactant And Phosphate, Soumyadeep Mukhopadhyay Dr, Mohd Ali Hashim Dr, Matthew Allen Mr, Bhaskar Sen Gupta Dr
Soumyadeep Mukhopadhyay Dr
An environment friendly arsenic removal technique from contaminated soil with high iron content has been studied. A natural surfactant extracted from soapnut fruit, phosphate solution and their mixture was used separately as extractants. The mixture was most effective in desorbing arsenic, attaining above 70 % efficiency in the pH range of 4–5. Desorption kinetics followed Elovich model. Micellar solubilization by soapnut and arsenic exchange mechanism by phosphate are the probable mechanisms behind arsenic desorption. Sequential extraction reveals that the mixed soapnut–phosphate system is effective in desorbing arsenic associated with amphoteric–Fe-oxide forms. No chemical change to the wash solutions was observed …

Cement production at Yandev, Nigeria commenced in 1980 without an environmental impact assessment to ascertain the extent of damage production activities would bring to bear on the physical conditions of the host environment. This study was carried out to provide baseline data on the rate and pattern of plume rise from the factory. Field survey was employed for primary data collation, while secondary data (climatic and factory data) were acquired from NIMET Makurdi Office and Dangote Cement Plc. Plume rate was estimated using the Gaussian (Mathematical) Model; Kriging, using Arc GIS, was adopted for modelling the pattern of plume dispersion. …
