Detailed Explanation

Mercury is widely used in artisanal and small-scale gold mining (ASGM) to extract gold from ore.

During this process, mercury binds with gold to form an amalgam, which is later heated, releasing toxic mercury vapors.

Mercury is a highly toxic heavy metal with no safe level of exposure.

Even low concentrations can cause neurological damage, developmental disorders, and kidney damage.
