Artisanal and small-scale gold mining (ASGM) is the largest source of mercury (Hg) emissions and releases worldwide. The breakdown of anthropogenic Hg emissions by sectors shows that the predominant source sector is ASGM that annually releases about 1220 Mg of Hg into the atmosphere, terrestrial and freshwater environments. Over the last 50 years, Hg has been used in ASGM practices in more than 70 countries by approximately 14–19 million people-including 4 to 5 million women and children, employed as miners.
