Apr 30, 2020 As the name suggests, the project aim is to determine the state of contamination and human exposure from artisanal gold mining, focusing on the Alto Cauca basin. Inhaling mercury vapour is most dangerous, and those that manipulate the mercury directly in the process of gold extraction, especially by burning mercury, are therefore most at risk.
