#0183;#32;In artisanal and smallscale gold mining (ASGM), Hg based gold extraction is a common practice. With 37%, ASGM represents the greatest source of anthropogenic Hg pollution ( Gibb and O''Leary, 2014; Telmer and Stapper, 2012 ). Worldwide, around 14 to 19 million people work in ASGM ( Seccatore et al., 2014; Steckling et al., 2017 ).

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 yr1, from at least 70 countries. 350 Mg yr1 of this are directly emitted to the atmosphere while the remainder (650 Mg yr1) are released into the hydrosphere (rivers, lakes, soils, tailings).
Artisanal and SmallScale Mining occurs in approximately 80 countries worldwide. There are approximately 100 million artisanal miners globally. Artisanal and smallscale production supply accounts for 80% of global sapphire, 20% of gold mining and up to 20% of diamond mining. It is widespread in developing countries in Africa, Asia, Oceania, and
#0183;#32;Artisanal and smallscale mining (ASM) is a significant source of income for tens of millions of people in developing countries. ASM refers to small groups and individuals engaged in lowcost and laborintensive excavation of minerals using minimal mechanization. ASM techniques are used in the production of precious minerals such as gold and diamonds, fertilizers used in agriculture, garnet used
In many countries, elemental mercury is used in artisanal and smallscale gold mining. Mercury is mixed with goldcontaining materials, forming a mercurygold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous
#0183;#32;In artisanal and smallscale gold mining (ASGM) the toxic metal mercury is used for gold extraction. The objective of this crosssectional study was to assess mercury concentrations in urine and blood and mercuryrelated symptoms of participants identifying themselves as miners from Kadoma and Shurugwi, Zimbabwe.
Artisanal and smallscale mining (ASM), which refers to mining with minimal or no mechanization often in the informal sector, has increasingly captured the interest of governments, international organizations, and private corporations because of its growing role in national economies and its impacts on society and the environment.
Mercury releases to air, water and land from artisanal and smallscale gold mining (ASGM) are estimated to be over 2000 tonnes each year1. It is the sector demanding the largest quantity of mercury, with virtually all of the mercury used released to the environment. The
Artisanal and small scale gold mining (ASGM) UNITAR. Formalization Handbook. UNITAR, in collaboration with the UN Environment Global Mercury Partnership and a group of national and international experts, has developed the Handbook for Developing National ASGM Formalization Strategies within National Action Plans.
There are 25 million people around the world working as artisanal and smallscale gold miners, and their work accounts for about 15% of the global supply (Metals Focus 2019). This represents a trade value of roughly 25 billion dollars and the investment potential is huge.
ARTISANAL AND SMALLSCALE GOLD MINING AND HEALTH VI Foreword Millions of people in the developing world depend on artisanal and smallscale gold mining (ASGM) for their livelihoods. This wealth, however, can come at a price. ASGM has many associated environmental and occupational health issues, particularly when
Name of conflict: Artisanal Smallscale Gold Mining, Uganda: Country: Uganda: Location of conflict: Exploitation of gold in the country has been concentrated in a few areas such as Kigezi, Mubende, Karamoja in northeastern Uganda, Buhweju and Ibanda in the West, Namayingo and Busia in eastern Uganda, Kitumbi in Central Uganda.
Artisanal and SmallScale Gold Mining Partnership Area ASGM Partnership Area Goal: reduce mercury use in ASGM by 50% by 2017 Main activities: Help Countries with Setting Goals and Targets Reduce High Risk Practices and Promote Cleaner Technologies
In Ghana, artisanal and smallscale mining (ASM) has grown in size and significance. Its contribution to wealth creation, employment and the economy makes it one of the nations most important livelihood activities, employing an estimated one million people and supporting approximately million more.
#0183;#32;Artisanal and smallscale gold mining (ASGM) has long been practiced in Nigeria and around the world. Bolstered by historically high gold prices, a lack of viable alternative livelihoods, and a ready if expensive supply of mercury, there has been a resurgence of ASGM activities in northern Nigeria in recent years.
