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 and lead to significant mercury exposure and health risks.
Smallscale gold miners use mercury to extract the gold from the ore. Environmental and health assessments of gold mining areas in Indonesia, Tanzania and Zimbabwe showed a high exposure with inorganic mercury in these gold mining areas, and a negative health impact of the exposure to the miners and the communities.
The artisanal smallscale gold mining (ASGM) sector exposes miners to toxic mercury when they use the chemical to extract gold from ore. However, with the right policies and market incentives, ASGM presents an opportunity to fight mercury use and contamination, protecting miners'' health and the environment at the same time.
