Artisanal smallscale gold mining (ASGM) is the largest single anthropogenic source of mercury emissions. Mercury is used in excessive amounts to extract gold from crushed ore in ASGM. Through pollution of the air, water and nutrients, the mercury causes adverse health effects in miners and their families. However, ASGM can be performed without the use of mercury.
