The artisanal smallscale 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. The Global Environment Facility (GEF) is looking to
