Artisanal gold‐mining (AGM) is one of the most important activities in the districts of Migori and Transmara (Kenya). Gold‐mining, however, is known to release vast quantities of arsenic and metals (some of which are very toxic like As, Hg, Cd, or Pb), which poses a serious threat to not only miners but also to the ecosystem and local populations.
The results of this study are in line with the result of a study (Eludoyin et al., 2017) saying that gold mining activity causes land degradation and loss of soil nutrients. Other studies have also proved that C-organic contained in the soil in mining areas decreases (Mushia et al., 2016).
