1. Introduction. Artisanal and small-scale gold mining (ASGM) is the largest anthropogenic source of mercury emissions. Approximately 200 metric tons of elemental mercury are commercialized every year for ASGM purposes; this accounts for 30 % of the total mercury used in industrial applications (Gallo Corredor et al., 2021; Yoshimura et al., 2021).
