Evaluating Wildlife Vulnerability to Mercury Pollution From Artisanal and Small-Scale Gold Mining in Madre de Dios, Peru K. E. Markham1 and F. Sangermano2 Abstract Illegal, artisanal and small-scale gold mining (ASGM) often occurs in remote highly biodiverse areas, such as …
the air, water, and soil. Specifically, mercury used to extract gold bioaccumulates in the environment, contaminating rivers and watersheds and posing a danger to wildlife in regards to its developmental, hormonal, and neurological effects. To conceal these typically illegal operations happening along rivers, artisanal and small-scale gold mining
But most people know little about the environmental impacts of gold mining. About 15% of world gold production is from artisanal and small-scale mining in over 70 countries throughout Asia, Africa and South America. These operations employ 10 to 19 million workers. They often are poorly policed and weakly regulated.
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 grant provides funding to evaluate ore-testing processes that have the potential to significantly reduce or eliminate the inadvertent release of 5,440 kg of toxic mercury every day by more than 15 million artisanal and small-scale gold miners (ASGM) around the world.
The Mercury Problem in Artisanal Gold Mining. Mercury-based artisanal and small-scale gold mining (ASGM) causes more mercury pollution than any other human activity. 1 In this practice, mercury metal is used to extract gold from ore as a stable amalgam. The amalgam is then heated to evaporate the mercury and isolate the gold.
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.

Mercury Free Mining's Mission. Over 15 million artisanal and small-scale gold miners (ASGM) in developing countries eke out a meager existence—and they have no alternative to using toxic mercury as part of their gold-extraction process. Unfortunately, there is a tragic, hidden cost, (15-20 million) miners' health, and our planet at large.
Mercury is used globally to extract gold in artisanal and small-scale gold mining. The mercury-free gravity-borax method for gold extraction was introduced in two mining communities using mercury in the provinces Kalinga and Camarines Norte. This article describes project activities and quantitative …

Mercury.1 Article 7 and Annex C of the Convention address artisanal and small-scale gold mining (ASGM).1 Annex C addresses the development of national plans for ASGM including a public health strategy that addresses the gathering of health data, training for health-care workers and awareness-raising through health facilities. Mercury Use in ASGM
Artisanal and small-scale mining activities are most evident among communities surrounding the Acupan River in Itogon Benguet. The mining activities include manual extraction of gold ores, use of improvised ball/rod mills and sluice boxes, and metallurgical processing such as cyanidation, carbon-in-pulp (CIP) and amalgamation. This study evaluates the influence of small-scale mining …
Small-scale gold mining operations in developing countries are major sources of toxic mercury pollution, using techniques that haven't changed much since the California Gold …
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 particularly rhetoric of loss, entitlement, endangerment ...

The Minamata Convention on Mercury and Artisanal and Small Scale Gold Mining. 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.
Mercury pollution in artisanal and small-scale gold mining (ASGM) is widespread throughout the Philippines. Amalgamation, or the use of mercury in gold recov...

In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically iso-lated by hand and then heated—often with atorch or over astove—todistill the mercury and isolate the gold ...
We estimate that artisanal and small scale gold mining releases between 640 to 1350 Mg of mercury per annum into the environment, averaging 1000 Mg yr -1, from at least 70 countries. 350 Mg yr -1 of this are directly emitted to the atmosphere while the remainder (650 Mg yr -1) are released into the hydrosphere (rivers, lakes, soils, tailings).

increase of global mercury pollution. The treaty designed to protect human health and nature, the "Minamata Convention", has been signed by the majority of world countries. Signatory countries are obliged to start initiatives to reduce and, prefer-ably, even stop mercury use. Small-scale gold mining accounts for 37 % of global mercury ...
A major source of air pollution from mercury, artisanal and small-scale gold mining releases approximately 400 metric tons of airborne elemental mercury each year. Located in over 55 countries, small scale gold buying and refining facilities (commonly referred to as "Gold Shops") are an important part of this production process, and are a ...
Mercury (Hg) contamination in soil and forage plants is toxic to ecosystems, and artisanal and small-scale gold mining (ASGM) is the main source of such pollution in the Bombana area of Indonesia. Hg contamination in soil and forage plants was investigated by particle-induced X-ray emission analysis of samples collected from three savannah areas (i.e., ASGM, commercial mining, and control ...
Human exposure to mercury is a leading public health problem. Artisanal and small-scale gold mining (ASGM) is a major source of global mercury emissions. Although occupational mercury exposure to ...
Gold is everywhere in modern life, from jewelry to electronics to smartphones. The global electronics industry alone uses 280 tons annually. And that demand keeps growing. But most people know little about the environmental impacts of gold mining. About 15% of world gold production is from artisanal and small-scale mining in over 70 countries throughout Asia, Africa and South America.
Small-scale gold mining accounts for 37 % of global mercury pollution. Millions of poor people have to resort to this type of mining as the only way of sustaining their families. 2 A large part of the mercury used in the final step of gold extraction ends up as mm-sized droplets in dumps (tailings) from which mercury slowly evaporates to the ...
