Pawara area is a mining district in the eastern region of Cameroon. Mining generally artisanal and semi-mechanized, practiced by local miners immigrants from neighboring African countries China. The lack strict regulations control activities permits to use illegal substances, especially Hg gold separation. These expose toxic heavy metals pollution. This study highlights source concentration soi...

Artisanal gold mining causes widespread health problems due to illegal exposure hazardous inorganic compounds, such as arsenic (As) and mercury (Hg). The sources prevalence of pollution are strongly influenced by topography, stream dynamics, soil type, land use. In the present study, potential elements (PHEs), absorption abilities nanoparticles (NPs), ultrafine particles (UFPs) were analysed fr...

Wetland degradation due to anthropogenic activities including artisanal gold mining is widely common in Uganda, and this affects vegetation health status if not controlled. However, the use of Normalised Difference Vegetation Index (NDVI) determine wetlands rare. In study, remote sensing techniques with spatial-temporal were used for Bitsya Subcounty, Buhweju district (noted mercury) wetland pe...

Diamond and gold mining has been practiced by artisanal miners in the Central African Republic (CAR) for decades. The recent introduction of riverine dredges indicates a transition from artisanal/manual digging sorting techniques to small-scale methods. This study implements remote sensing analysis Synthetic Aperture Radar (SAR) data map diamond operating on Kadéï (Sangha) river CAR. Riverine v...

Gold mining has played an important role in Ghana's economy, however the negative environmental and socio-economic effects on the host communities associated with gold mining have overshadowed these economic gains. It is within this context that this paper assessed in an integrated manner the environmental and socio-economic impacts of artisanal gold mining in the Tarkwa Nsuaem Municipality fro...

The Gold King Mine spill in August 2015 released 11 million liters of metal-rich mine waste to the Animas River watershed, an area that has been previously exposed to historical mining activity spanning more than a century. Although adsorption onto fluvial sediments was responsible for rapid immobilization of a significant fraction of the spill-associated metals, patterns of longer-term mobilit...
