In addition to loss of livelihoods, local populations may lose access to potable water, due to the heavy use of mercury in artisanal gold mining.[62] Largescale mining operations can also disrupt water sources.[63] Mine shafts in artisanal mining are constructed with trees, which can contribute to deforestation.[64]
Artisanal and smallscale gold mining (ASGM) is a crucial economic activity in Burkina Faso, however it is associated with significant mercury exposure and health concerns. The aim of the present study was to assess the level of mercury (Hg) vapour exposures and occupational behaviours at a representative site using Hg vapour monitor badges...

Mercury is not used for processing in largescale mining, but at some gold mines mercury is produced as a byproduct where it occurs naturally in the ore body, usually in the form of a stable compound of mercury sulphide. In the artisanal and smallscale mining (ASM) sector, pure mercury is commonly used for gold recovery, sometimes illegally.
