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 .

Issues. Artisanal mining can include activities as simple as panning for gold in rivers, to as complex as development of underground workings and small-scale processing plants. In any of these circumstances, issues can stem from difficulties in achieving regulatory oversight of a large number of small operations (including issues such as security of land tenure for artisanal miners, to .

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.

Artisanal and Small-Scale Mining In many parts of the world minerals are extracted by artisanal and small-scale miners –people working with simple tools and equipment, usually in the informal sector, outside the legal and regulatory framework. There are also many artisanal mineral processors, such as diamond polishers. The vast majority are very poor, exploiting marginal deposits
