A large anthropogenic source of mercury pollution is mercury-dependent artisanal and small-scale gold mining (ASGM). Thabeikkyin Township is a small-scale gold mining township located in Pyin Oo ...
1. Introduction. Artisanal and small-scale gold mining (ASGM), characterized by rudimentary mining methods, low-grade ore, and limited ore production (Malehase et al., 2016), is attributed with releasing 37.7 % of anthropogenic emissions of mercury to the atmosphere (UN Environment, 2019).Because it is the largest anthropogenic sources of …
Although most of the participating countries have already signed and ratified this convention, mercury pollution in the artisanal and small-scale gold mining sector remains a major challenge. The aim of this systematic review was to examine the situation of occupational mercury exposure and mercury-related health effects among ASG …
The increased research attention on estimating the global mercury use and emissions in artisanal and small-scale gold mining (ASGM) has improved awareness of the problems associated with ASGM.
1. Introduction. Artisanal and small-scale gold mining (ASGM) is the largest source of mercury (Hg) emissions and releases worldwide (UNEP, 2018).The breakdown of anthropogenic Hg emissions by sectors shows that the predominant source sector is ASGM (about 38%) followed by stationary combustion of coal (about 21%).
Abstract. With the aim of protecting human life and the environment, the Minamata Convention seeks to reduce and monitor mercury (Hg) concentrations in the environment. Artisanal and Small-scale Gold Mining (ASGM) has been identified as the most important anthropogenic source of Hg at a global scale and an important route of human exposure …
Abstract. Establishing quantitative baseline estimates of mercury use in artisanal and small-scale gold mining is necessary to meet the requirements of the …
1. Introduction. Disparate and incomplete data makes it challenging to address the complex and multifaceted issues involved in mining (Lèbre et al., 2019, 2022).A prominent example is artisanal and small-scale mining (ASM), which is conducted by individuals, groups, families, or cooperatives, typically with minimal or no …

Artisanal and small-scale gold mining (ASGM) utilizes mercury (Hg) for the extraction of gold (Au) and is responsible for the largest anthropogenic source of emissions and releases of Hg to the environment. Previous estimates of Hg use in ASGM have varied widely. In this effort, Hg losses in ASGM were derived from the difference between ...
Mercury-dependent artisanal and small-scale gold mining (ASGM) is the largest source of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically isolated by hand and then heated-often with a torch or over a stove-to distill the mercury and isolate the gold. …
The children who worked in small-scale gold mining operations in Indonesia and Zimbabwe ranged in age from 9 to 17 years. Umbangtalad et al. (2007) found that Thai schoolchildren living near, but not working in, small-scale gold mining operations had increased urinary Hg concentrations. Hair Hg reflects the ingestion of Hg from fish …
Introduction. Artisanal small-scale gold mining (ASGM) is the largest consumer of mercury worldwide and the largest anthropogenic source of mercury emissions in the environment. 1 In ASGM, gold is extracted using rudimentary techniques, including the use of mercury to bind the gold contained in the ore. 2 Smelting the …
1. Introduction. Mercury (Hg) releases from artisanal and small-scale gold mining (ASGM) is estimated to be about 1400 t/year (UNEP, 2013), making it the largest global demand sector for Hg and the largest source of Hg pollution in Colombia (De Miguel et al., 2014, García et al., 2015).This country is the highest per capita Hg polluter in the …
Artisanal and small-scale gold mining (ASGM) in Tanzania results in occupational exposures and environmental contamination to toxic chemical elements such as arsenic and mercury. Populations living in such areas may be exposed by various routes, and prenatal exposure to arsenic and mercury has been associated with adverse birth …
The Minamata Convention on Mercury is increasing global interest in mercury pollution reduction activities, particularly in the area of Artisanal and Small Scale Gold Mining (ASGM). For most developing countries, ASGM is the largest source of mercury pollution. According to UNEP's most recent Global Mercury Assessment in …
Mercury used in gold mining can be a problem that includes environmental risks and health risks for miners and others. Here is why you should be cautious. ... Under the socio-economic and political conditions …
Artisanal small-scale gold mining (ASGM) is one of the major sources of mercury pollution in Indonesia. The village of Bunikasih, near Bandung, the capital city of West Java, is an ASGM operation that has developed since 1993. We investigated mercury exposure of soil...

The use of mercury in artisanal small-scale gold mining has generated intense debate because of its deleterious effects on human health. A narrative policy analysis of artisanal gold mining debates in Ghana's parliament was carried out in this study. The results show that civil society and policy makers use various rhetorical idioms …
Although many miners use mercury in artisanal and small-scale gold mining, it is possible to safely and economically recover gold without it. Mercury-free …

An inventory of mercury in Colombia for 2011 estimated that 140 metric tons of mercury are released into the environment each year from artisanal and small-scale mining (Brooks, 2012). ...
Mining process on a small-scale gold mine site in Burkina Faso. A mining process, involving mercury extraction, in small-scale gold mine sites includes typically eight operations. The gold ore is first extracted from the mine and then crushed in order to get more small pieces (Fig. 1a). The grinding of the gold ore transforms it in a fine powder.
The small-scale gold mining industry is the largest contributor to mercury emissions with a total of 38% globally from 2010 to 2015 . Indonesia is referred to by the United Nations as the third largest mercury emitter in the world, after China and India.
Mercury (Hg) is used by small-scale gold miners in more than 50 developing countries, where the accompanied releases affect human health and the environment. …
Artisanal and small-scale mining emits over 2,000 tonnes of mercury per year. This includes emissions to air from heating amalgams, as well as direct losses of mercury to land and water. The chemical, which has …
