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 million …
