Mercury (Hg) is one of the most harmful metals and has been a public health concern according to the World Health Organization (WHO). Artisanal and small-scale gold mining (ASGM) is the world's fastest-growing source of Hg and can release Hg into the atmosphere, hydrosphere, and geosphere.

Mercury is a highly toxic element with no known safe level of exposure (Bose- O'Reilly et al., 2010) which is an inexpensive reagent used in amalgamation process in artisanal gold mining. By using this ancient technique, gold forms an amalgam, usually with 50–60% Au–Ag, that can be separated from the rest of the minerals.

Introduction. For more than two decades, artisanal and small-scale gold mining (ASGM) has been operated in Indonesia, spread widely across 31 provinces.1 In West Java Province, ASGM is found in Bogor, Cianjur and Sukabumi Regencies. Commonly, ASGM in Indonesia uses mercury (Hg) in gold ore processing.2 Mercury is …

Abstract and Figures. The paper examines the environmental impact of artisanal mining of gold with mercury (Hg) in Ghana. In spite of its positive socio- economic contributions, it is well known ...

The burning of the gold-mercury amalgam also emits enormous quantities of mercury into the atmosphere. Artisanal gold mining currently contributes more than 35 percent of all global mercury ...

Artisanal mining employs about 6 million people in China, who often work in deadly conditions, and contributes to environmental degradation on a huge scale. Chinese artisanal mercury, coal, and gold miners emit hundreds of tonnes of mercury into the environment annually. Artisanal gold miners often use muller mills, which amalgamate …

The mercury concentration in the Ayeyarwady River and the groundwater pumped from the gold mining tunnel was 4.6 ng/l and 29-35 ng/l, respectively. The limit of mercury in hair is considered to be 50 μg/g, at which concentration nervous symptoms may appear, while 11μg/g is the concentration at which adverse effects on fetuses could take …

Artisanal small-scale mining is widely operated in various countries serving as a livelihood to many rural communities. However, it is a significant source of environmental mercury contamination which affects human health. Amalgamation and amalgam smelting, two significant steps in the artisanal small-scale mining operations …

Artisanal and small-scale gold mining (ASGM) is the leading source of mercury (Hg), a global neurotoxin. Past research has focused on the health impacts on miners and nearby residents; here, we estimate the risk for global general populations by employing a comprehensive atmosphere-land-ocean-ecosystem and exposure-risk …

Indonesia is host to a long history of gold mining and is responsible for a significant contribution to world gold production. This is true not only with regard to large gold mining companies but also to small-scale mining groups comprised of people and enterprises that participate in the gold industry of Indonesia. More than two thousand …

Mercury (Hg) use in artisanal and small-scale gold mining (ASGM) is globally the largest source of occupational health exposure to Hg. 1 In this type of mining, Hg is used to extract gold from its ore by forming an amalgam, which is then burnt, leaving the final gold product. 2,3 These extraction processes expose artisanal and small-scale …

Mercury (Hg) is a widespread persistent pollutant that is released to the environment from both natural and anthropogenic sources (Pirrone et al., 2010; UNEP, 2013). Of particular concern is its... Fate of mercury from artisanal and small-scale gold mining in tropical rivers: Hydrological and biogeochemical controls.

Artisanal and small-scale gold mining (ASGM) is a major contributor to deforestation and the largest anthropogenic source of atmospheric mercury worldwide. Despite significant information on the direct health impacts of mercury to ASGM miners, the impact of mercury contamination on downstream communities has not been well characterized ...

For the last 40 years artisanal mining has been playing a key role in the economy of the Madeira River, State of Rondônia, in the Brazilian Amazon.The main process through which artisanal miners in the region recover gold is by river dredging.The dredges are floating platforms that excavate the bottom of the river and, after a sorting …

Artisanal and small-scale gold mining uses mercury to isolate gold from ore. Although uncommon in the United States, it is more common in poor and undeveloped countries. This practice requires heating mercury, which vaporizes into an odorless gas that can be inspired and absorbed into the blood. Inspired mercury vapors place individuals at risk ...

In the case of an ore that contains 10 times more silver than gold, about 20 times more mercury is added in order to capture the gold. The silver is also captured, and even though it is worth 40 times less than the gold, it is still profitable and sought after, but by using mercury much more intensely. The effect silver on mercury use is ...
