UN expert calls for a global ban on mercury trade and use in small
"The use of mercury for small-scale gold mining is the main source of mercury pollution globally. The mercury trade is driven by the insatiable demand for gold in the financial and jewellery markets. Refineries purchase gold without adequate due diligence mechanisms to address human rights abuses," Orellana said.
The Mercury-Gold Relationship: Mercury Use in Small-Scale Gold Mining
Mercury has been used for the past fifty years in artisanal small-scale mining methods in roughly eighty countries, and its use is increasing. Between 1996 and 2002, a modern gold rush was triggered by a 10-fold increase in the price of gold, and other factors such as increasing poverty are driving more people toward gold mining, using whatever ...
The dynamics of mercury around an artisanal and small-scale gold mining
To elucidate the dynamics of mercury emitted and released by artisanal and small-scale gold mining (ASGM) activity and to estimate its impact on the ecosystems of the bay, the distribution of mercury in the atmosphere, soil, water, and sediment around Mambulao Bay, Camarines Norte, Philippines, was investigated. The ASGM operations …

The end result is that mercury releases were reduced by an estimated 3,000 kg in one year. Amit now uses a retort, a device which takes the mercury vapour up through a pipe and allows it to condense in a water tray. This means the toxic fumes are not released and the mercury can be used many times over, protecting the health of the miner and ...
