Management of coal processing wastes: studies .

Management of coal mining and coal processing wastes, particularly of high sulfur coals, can generate excessive amounts of sulfate (SO4 2−) and chloride (Cl−) in mine drainage that are known to negatively impact quality of both surface and ground water. The U.S. Environmental Protection Agency provides guidance to states on allowable SO4 2− and Cl− discharges from mine sites.

Mercury inhibits sulfur ligands in MT and in the case of intestinal cell membranes inactivates MT that normally bind cuprous ions (125,141), thus allowing buildup of copper to toxic levels in many and malfunction of the Zn/Cu SOD function. Another large study (114) found a high percentage of autistic and PDD children are especially susceptible to metals due to the improper functioning of their ...

74. Mining and Quarrying - ILO Encyclopaedia

The first is the mining and quarrying of industrial and construction materials on a small scale, operations that are mostly for local markets and present in every country (see figure 1). Regulations to control and tax them are often in place but, as for small manufacturing plants, lack of inspection and lax enforcement mean that informal or illegal operations persist.
