Mercury use in


ASGM was estimated by Mercury Watch at 1,400 tonnes in 2011.


ASGM is the largest sector of demand for mercury, using it to separate the metal from the ore. At least 10–15 million min- ers are involved worldwide, mainly in Africa, Asia and South America. An estimated three million of them are women and children (UNEP, 2012). Mercury use in ASGM was estimated by Mercury Watch at 1,400 tonnes in 2011, and rising gold prices are likely to increase that use (UNEP, 2012). The prac- tice threatens the health of the workers and their families, and the people downstream who eat mercury-contaminated fish or drink the water. It can also cause environmental damage


that may persist for decades after the mining has stopped. Low-mercury and mercury-free methods are available, but socio-economic conditions are often barriers to the adoption of better practices (UNEP, 2012). Persuading miners to change the way they work because mercury is a threat to them and their families can be difficult, but some good examples exist. The Sustainable Artisanal Mining project in Mongolia, sup- ported by the Swiss Development Cooperation, is one such initiative, involving the Mongolian Government in working with miners to develop policies and technical solutions to
