15/8/2016Objective: This study aimed to study the mobility of heavy metals using sequential extraction analysis and assess heavy metals in soil samples of mining tailing around the small-scale gold mining areas at Boroo and Zuunkharaa in Mongolia.Methodology: The samples were collected from small scale gold mining area existed in Tov and Selenge province, Mongolia.
30/04/2020In the southwestern forests of Ghana, for instance, the footprint of small-scale mines is nearly seven times greater than that of industrial mines. The mercury and heavy metals used in galamsey can contaminate drinking water for entire communities. It also causes major health issues, such as kidney problems and neurological disorders, to those continually exposed to the metals. The Ghanaian
recorded concentrations in the sensitive areas exceeded greatly. Hence the levels of heavy metal contamination have spread beyond control. Keywords Small-Scale Gold Mining, Mercury Pollution, Heavy Metal, Dunkwa -on-Offin, Ghana *Corresponding author.
1/12/2015As gold is the main contributor to Ghana's economy, accounting for 38% of total stock and 95% of total mineral exports,5 small-scale mining as well as improper regulation of large-scale mining pose enormous environmental challenges such as land degradation, subsidence due to gold mining and water pollution, all of which pose risks to human health.6–8 Wastes from mining processes such as
16/6/2018Heavy metal contamination of selected rivers in Ghana was studied as part of a bigger project aimed at setting background standard for heavy metals in the Ghanaian environment. Water samples were collected from major mining and eight pristine areas. The samples were acid digested with aqua-regia and analyzed with ICP-MS for As, Cd, Hg, Zn, Cu, Mn, Fe, Cr, Al, V, Co, Ni, and Pb.
17/5/2017The high incidence of "galamsey" or illegal mining in recent times, have been on several discussions and heated debates for some time now and has perplexed the minds of the general public in Ghana.

1/1/2015Background. Ghana, like many countries in Africa, has a history of heavy metal pollution largely emanating from industrial effluent discharges and anthropogenic deposits on prevailing winds of pollutants from industrial activities. One of the biggest contributors to pollution in the Ghanaian environment is mineral mining. Objectives.
16/06/2018In the case of arsenic, the mean As values were 180 mg/L Obronikrom and 46 mg/L each Kibi-Deaf and Bunso . The average metal concentrations of As and Pb reported in this study are comparable to the concentrations reported in other studies around gold mining areas in Ghana Obiri et al. 2016; Cobbina et al. 2013; Rajaee et al. 2015 . In a separate study in 2013, Cobbina et al. found relatively low concentrations of heavy Cited by: 11
14/06/2021The team found more than 160,000 hectares 400,000 acres of vegetation were lost from 2005-2019. About 28 percent was lost to both industrial and artisanal gold mining, while 29 percent was lost to urban development. About 17 percent was converted to water, mainly due to the formation of a
This study assessed the level of heavy metals in five streams lo ed at Mile 7 and Teberebie in the Tarkwa gold mining district of Ghana using instrumental neutron acti ion analysis INAA and pollution indices. It was aimed at providing information on the concentrations of ten
Heavy metals concentrations in water and sediment samples collected from five streams in Tarkwa gold mining district of Ghana were studied. The water and sediment samples were analysed for As, Al, Cd, Co, Cu, Hg, Mn, Sb, Th, and V, using Instrumental Neutron Activation Analysis INAA . The results of this study generally showed elevated levels of all the ten examined elements in the water and
