The artisanal gold mining sector employs millions of people but is mostly informal and unlicensed (Hilson Citation 2020; Hilson et al. Citation 2018), leading to significant mercury emissions into the environment, up to 2000 tons per year (Martinez, Restrepo-Baena, and Veiga Citation 2021). In South America, artisanal miners use 'mercurio ...
The Kitazawa area in Aikawa is home to a group of facilities, such as a power plant and a thickener (designated National Historical Site), which contributed to the modernization of mines.
