Mercury pollution in most parts of the regions in the world are caused by the release into the environment of metallic mercury used in the recovery of gold by the crude method of amalgamation. Currently, countries such as in Brazil, Ghana, Tanzania, Philippines, Indonesia, China and Vietnam with roughly 10 million people are estimated to be involved in these activities. In China alone, 13 % of the total gold output is said to be produced from the amalgamation process which accounts for 20 tons o f Hg released into the environment. China ranks fifth in the world gold production output with South Africa having the largest total gold production. Presently, in 55 countries engaged in small-scale mining activity it was estimated that 8.25-10.1 million people have been directly involved with an additional 80-100 million being dependent on this activity for their livelihood. For 10 Asia-Pacific countries, it was estimated that total employment from small-scale mining is from 6.0-6.6 million wh ich would account for 73% of the global estimates.
