This paper is one of three synthesis documents produced via an integrated assessment (IA) that aims to increase understanding of artisanal and small-scale gold mining (ASGM) in Ghana. Given the complexities surrounding ASGM, an integrated assessment (IA) framework was utilized to analyze socio-economic, health, and environmental data, and co-develop evidence-based responses with stakeholders. T...
Artisanal and small-scale gold mining (ASGM) is inherently risky, but little is known about mining-associated hazards and injuries despite the tremendous growth worldwide of ASGM and the benefits it offers. The current study aimed to characterize the physical injuries associated with ASGM in Ghana to guide policy formulation. A cross-sectional survey was carried out in the Tarkwa mining distric...
Introduction Artisanal gold mining is an activity ensuring the survival of about 700,000 families in Burkina Faso with a considerable contribution to the national economy. Techniques and chemicals used in the operation, have adverse impacts on health and the environment. Our study aims to evaluate the perceptions and knowledge of these different impacts among artisanal gold miners. Methods A ...
Mining is one of the oldest economic activities mankind. Within this activity, artisanal and small-scale gold mining (ASGM) most studied sectors due to its high level environmental contamination social problems it causes. In recent years, ASGM in northern Amazon Ecuador has increased significantly, studies that describe current situation impact are scarce. sense, present study aimed analyze sta...
OBJECTIVES Gold miners use mercury to extract gold from ore adding liquid mercury to the milled gold-containing ore. This results in a mercury-gold compound, called amalgam. Miners smelt this amalgam to obtain gold, vaporizing it and finally inhaling the toxic mercury fumes. The objective was to merge and analyze data from different projects, to identify typical signs and symptoms of chronic in...
In this paper, we propose a system dynamics (SD) model to examine the of an informal artisanal and small-scale gold mining (ASGM) supply chain that has interactions with illegal in Amazon rainforest region, Madre de Dios (MdD), Peru. order under climate impacts validate model, run it flood scenario, which is one main causes disruption activities. Our findings suggest mines are highly affected b...
The radioactivity associated with artisanal and small-scale gold mining activities (ASM) carried out along the Ulindi River, in eastern Democratic Republic of Congo, was evaluated by gamma-ray spectrometry inductively coupled plasma–mass soil sediment samples. results revealed that activity concentrations 238U (up to 3127 ± 98 Bq kg?1), 226Ra 2710 89 kg?1) 232Th 2142 162 were 71- 89-fold higher...
Artisanal and small-scale gold is known to be sources of mercury pollution. This contamination occurs when isolated by the amalgamation method, occurs. Mercury pollution in artisanal mining Kulon Progo area Yogyakarta, lowest tailing content was 164.49 mg kg<sup>-1</sup>, highest 383.21 kg<sup>-1</sup>. value exceeded quality standard stipulated Indonesian Government Reg...
