There is concern that work scenarios on the tantalite mining sites in Oke-Ogun, Oyo State, Nigeria may cause occupational radiation exposure of workers due to enhanced concentrations naturally occurring radionuclides some process materials. A prior radiological assessment activities was carried out determine if and which require protection measures. Samples materials involved, comprising (tanta...
This study aimed to determine levels of cyanide (CN) pollution in the soil and surface water at selected mining sites Mbeya region. A total (n = 124) samples were collected analyzed by spectrophotometry. The soil-based water-based Mwasenga, Ifumbo above permissible limits. was due poor disposal tailing from gold processing plants mismanagement wastewater. On other hand, Cyanide within allowable...

the quality of hg contaminated sediments in artisanal gold mining areas of tanzania have to date only been assessed through bulk chemical analysis. however, measurement of contaminant levels alone has a limited ability to predict adverse effects on living resources. in this study we investigated the possible effects of hg contaminated sediments from the river mabubi which drains the artisanal g...
An innovative remote sensing approach that combines land-use change and water quality information is proposed in order to investigate if Artisanal and Small-scale Gold Mining (ASGM) area extension is associated with water siltation in the Tapajós River Basin (Brazil), containing the largest small-scale gold mining district in the world. Taking advantage of a 40-year period of the multi-satellit...
