The gold mining and smelting have an heavy impact on surface water and even leading to combined pollution of heavy metals including Hg Zn Cd serious pollution Cr and As moderate pollution Pb and Cu less pollution Spatial variation of heavy metals in surface water in study area The spatial distribution of heavy metals along the stream
About nine million Artisanal and Small scale Gold Mining ASGM workers in Africa and people living near ASGM activities are highly exposed to geogenic and anthropogenic potentially toxic elements PTEs Despite the hazards and risks posed by ASGM being well characterized coordinated multidisciplinary environmental characterization with combined
South Africa has failed to address the adverse environmental and health effects of more than 130 years of gold mining in and around Johannesburg a new report from Harvard Law School shows

Artisanal and small scale gold mining ASGM is the largest anthropogenic source of mercury emissions Approximately 200 metric tons of elemental mercury are commercialized every year for ASGM purposes; this accounts for >30 % of the total mercury used in industrial applications Gallo Corredor et al 2021; Yoshimura et al 2021 Due to the
Gold mining is now the world s top source of mercury pollution emitting more than coal fired power stations A 2022 study led by Gerson found trees and birds in Madre de Dios contained mercury at levels resembling contaminated industrial regions in China What all this mercury pollution is doing to residents including nearby Indigenous
A boom in small scale gold mining in Bolivia has raised concerns about pollution from mercury used in the mining process Researchers are citing the health impacts on downstream villages but the government has yet to act to stem the widespread use of
Mining is essential for societal development as it supplies essential raw materials for various industries However it can occasionally negatively impact ecosystems and populations [1 2 3 4 5 6] One of the main concerns associated with mining activities is the potential release of high toxicity pollutants into the environment [7 8 9] Some potentially toxic
5 The main source of mercury pollution in the Amazon is artisanal and small scale gold mining which accounts for 15 per cent of the gold extracted from the region Mercury is used in the gold purification process contributing around 71 per cent of all mercury emissions each year
In this paper the status of metal pollution in the abandoned gold mining district of Bindiba was assessed using pollution indices multivariate analysis and geostatistical modelling 89 soil samples were systematically collected and characterized to determine their levels of TMs Cr Ni Cu As Pb and Sb The metal characterization of the
Industrial pollution open pit mining and land use change caused significant negative environment impacts by affecting regional water land and biodiversity resources Poiseev 1999;Savvinov 2000
Following the recent incident of lead poisoning in Zamfara State of Nigeria interest in the levels of heavy metals in environmental samples from the affected areas has increased In this regard we collected and analysed water and soil/sediment samples of Bagega artisanal gold mining region using flame Atomic Absorption Spectrometry AAS to assess the levels of heavy metals
The main objective of this study is to assess the level of heavy metals pollution in soil samples collected around gold mines located in Betaré Oya BO and Batouri BA in Eastern Cameroon Elemental analysis of soil samples was carried out using Quant´X EDXRF spectrometer Its sensitivity and accuracy were increased by using the Fundamental
The Council on Ethics of the Norwegian Government Pension Fund Global carried out a detailed survey on mining pollution at the oldest gold mining town Obuasi and found evidence of severe environmental and health damage due to high level of concentration of arsenic cyanide and heavy metals cadmium manganese lead and copper in
The heavy metal pollution indices demonstrated the high pollution impact of gold mining exploitation on the Lom River water resource rendering it unfit for various domestic purposes This study represents a preliminary step in the analysis of Bekao in terms of surface water pollution and health risks due to gold mining exploitation It also
The degree of pollution produced by a gold mining operation depends on the nature and composition of the extracted minerals Kyle et al 2011 2012; Luque Almagro et al 2016 the extraction process Higueras et al 2004; Olobatoke and Mathuthu 2016 and the taken remediation measures which are often inadequate or insufficient O
Gold mining has recently outstripped coal burning as the world s single largest source of airborne mercury pollution annually releasing as much as 1000 tons of the potent brain and reproductive poison into the atmosphere Using mercury to extract gold is a miner s dream The cheap liquid metal when mixed with a slurry of water and raw
Gold mining is an economic pressure valve for poorer countries he said And that has only been compounded by the 12 percent rise in gold prices over the past year to nearly $2 000 an ounce
This study evaluated the water quality pollution and health risks associated with illegal gold mining activities in two estuaries Pra and Ankobra in the Southwestern region of Ghana The Canadian Council of Ministers of the Environment Water Quality Index CCME WQI used for the evaluation indicated that both estuaries were in the marginal
Civil society groups have raised the alarm over pollution of rivers in eastern and northern Cameroon by gold mining companies The Centre for Environment and Development says two Chinese companies
Gold mining has serious negative environmental impacts especially due to pollution emanating from tailings storage facilities TSFs tailings dams slimes dams The most important forms of pollution from TSFs are acid mine drainage AMD and high levels of potentially toxic elements PTEs AMD arises from the high levels of pyrite in the mining ores which
