Historical mercury (Hg) discharged into the environment as a result of gold mining activities plotted as a function of selected geographical locations and time of mining activities.

A gold-mercury amalgam is formed, which is heated to vaporize mercury, leaving behind the gold. Mercury is widely available, even in remote communities, and it enables miners to produce gold (and thus income) on a daily basis. This means that mercury amalgamation is often the default solution, and as a result, ASGM remains the largest user and ...

In 2017, Human Rights Watch documented how children employed in the informal mining sector of Tanzania, unaware of the dangers of the metal, mix mercury into gold ore with their bare hands.
