Mining operations release heavy metals that can be extracted by water. Depending on the mine and its location, Ni, V, Cr, Mn, Cu, Pb, Zn and As can be released into the hydrosphere. Mercury Mercury was widely used to in California gold mines to extract the precious metal from solid ore.
All in all, there have been more studies of exposures to dust in gold, diamond and coal and asbestos mines than in other mines such as mines for vanadium, iron, uranium, nickel, copper, and so on. There is a need, therefore, to assess the hazards as well as to undertake health risk assessments for mines for which there is little information.
