A focus on Mercury
The mercury problem is a critical one. A paper from Flinders University found that between 410 and 1,400 tonnes of the element are emitted through artisanal and small-scale gold mining (ASGM)every year, with mercury-based ASGM causing more mercury pollution than any other human activity. While estimates vary, there are 15-20 …

Making mercury history in the artisanal & small-scale gold mining
The artisanal small-scale 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.
