It has several industrial uses such as thermometers, batteries, barometers among others. But mercury is also used in mines for the purpose of extracting gold and silver soil; this activity comes to affect on the environment and health. Most of the mercury released from human activities is released into air, through fossil, mining, smelting and solid waste combustion. Some forms of human activity release mercury directly into soil or water, for example fertilizer application in agriculture and industrial wastewater discharges. All mercury that is released to the environment will eventually end up in soils or surface waters.
