1. Introduction. Mercury (Hg) is a global toxin that can impact both human and ecosystem health (Driscoll et al., 2013).Exposure to Hg in humans occurs primarily via consumption of foods containing elevated levels of Hg, such as high trophic level fish and inhalation of Hg fumes (Niane et al., 2015).In artisanal and small-scale gold mining …
Since the rise of the gold price in 2000, artisanal and small-scale gold mining (ASGM) is a growing economic activity in developing countries.
