The assessment of heavy metal contaminants: Mn, Cr, V, Cu, Pb, Zn and Ni, was conducted on River Niger Floodplain soil at Jebba, Central Nigeria using Contamination Factor (Cf), Factor (AF), Enrichment Factor (EF), Geoaccumulation Index (Igeo) and Degree of Contamination (Cdeg). Random sampling method was adopted cutting across the entire floodplain and the samples were subjected to Inductively...

Platelet components (PCs) have widespread applications in clinical cases. Since PCs store in room temperature (between 20-24°C), they are susceptible to bacterial contamination. There are varied approaches for identifying bacterial contamination in PCs. These methods categorized into two groups: Firstly, culture based methods and secondly, non-culture based methods. Both of them have a coup...

Abandoned iron ore mining soil was analyzed for its metal contamination. Pollution indices were calculated and used to examine the potential of area be polluted by metals. The samples collected in triplicate from ten sampling points spread throughout area. energy dispersive X-ray fluorescence (EDXRF) analytical method determine concentrations Cd, Cu, Co, Pb, Zn, Fe, Cr, Ni, Mn. order mean (mg/k...

Presence of heavy metals in agriculture soils above the permissible limit poses threats to public health. In this study, concentrations of seven metals were determined in agricultural soils from Yuhang county, Zhejiang, China. Multivariate statistical approaches were used to study the variation of metals in soils during summer and winter seasons. Contamination of soils was evaluated on the basi...

This reports the study on the flow behaviour, heat transfer and contamination distribution in a room. For this purpose the 3-D incompressible Navier-Stokes equations, energy equation and a mass transfer equation which model the concentration of contamination have been applied. For turbulence simulation the two equation standard k-  turbulence model was employed. By means of SIMPLE algorithm the...

In this study, the concentrations of heavy metals (Ca, Zn, Cu, Fe, Mn, Ni) in thesediment of Shavoor River in Khuzestan Province in Iran has been investigated. After the library studies and field studies, six samples of water and sediment were taken from the river in order to evaluate heavy metal pollution in sediments. To determine the geochemical phases of metals in sediment samples the 5-ste...
