Much of the world’s mercury production is used in artisanal and small-scale gold mining (ASGM), where the metal is added to gold-containing ore in order to extract the precious metal. ASGM is also the world’s number one source of mercury pollution.
The UN Environment Programme’s (UNEP) Global Mercury Supply, Trade and Demand report revealed that Kenya, where UNEP is based, and South Africa are the main supply hubs for mercury used in ASGM, which is commonplace in east and central Africa.
