The study aimed to assess concentrations of heavy metals in soil samples on both sides along the three Niles (Blue, White, and Nile Rivers) Almogran area (Tuti Island) Khartoum city (the capital Sudan country) after overflow season. Concentrations Br, Cu, Ni, Pb, Co, Rb, Cr, Zn, Zr, Sr, Mn, Ti, K, Ca, Fe were determined using Xray fluorescence (XRF) techniques compatible with direct analysis s...

The current research aims to find the levels of mercury element in surface soils from selected locations Kirkuk Governorate and assess their ecological health risks it. Forty-one specimen were collected upper part Top soil at a depth 0-20cm analyzed with inductively coupled plasma mass spectrometry. results showed that total concentration this reached (47.19 μg/kg) Mercury high concentrations w...

The contamination levels and distribution of heavy metals were assessed in riverbed sediments water column samples from Mura Kimpulande Rivers, both impacted by copper-cobalt gold mining activities. Analyses performed using inductively coupled plasma-mass spectrometry (ICP-MS), atomic absorption (AAS), fluorescence (AFS). Results showed high concentrations Ni, Cu, Zn, As, Cd, Hg samples. rivers...

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...

Mining is an activity that involves the use of chemicals and results in unsustainable dangerous conditions for miners, their families, community surrounding ecosystem. This study was done to assess metallic contamination soils sediments Bétaré-Oya gold artisanal mine district, East-Cameroon. A total thirty (30) samples exploited soils, control were taken from mining sites Lom, Mbal Mali. The co...

Most HWRs currently use natural uranium fuel. Using enriched uranium fuel results in a significant improvement in fuel cycle costs and uranium utilization. On the other hand, reactivity changes of HWRs over the full range of operating conditions from cold shutdown to full power are small. This reduces the required reactivity worth of control devices and minimizes local flux distribution perturb...

To understand the heavy metal (Cd, Cr and Pb) pollution situation exposure risk of vegetables soil in Jinhua City, soil–vegetable samples collected from three districts City were analyzed detail, risks concentration vegetable evaluated using single index, Nemerow Hakanson potential ecological index a health assessment. The results indicate that: (1) is mainly polluted by Cd, BCF metals was leaf...
