World emissions of mercury from artisanal and small scale gold mining
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 yr -1, from at least 70 countries. 350 Mg yr -1 of this are directly emitted to the atmosphere while the remainder (650 Mg yr -1) are released into the hydrosphere (rivers, lakes, soils, tailings).

Artisanal and Small-Scale Gold Mining Without Mercury
In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold 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.
