“ＵＮＥＣＡ”（黄金提取和受控汞齐化单位）中心的概念是联合国工业发展组织和一家委内瑞拉私有公司共同提出的．它以委内瑞拉政府在１９９０年代初引进的“汞齐化中心”为基础．ＵＮＥＣＡ中心可以向手工业矿工提供安全的黄金提取服务和各种类型的培训．关于采矿健康与环境影响的信息（具体地说，需要避免汞蒸气吸入和食用有汞污染的鱼）可以通过这些中心传播给矿工及其家庭 The UNECA (gold extraction and controlled amalgamation) center concept was co-sponsored by the United Nations Industrial Development Organization and a privately owned Venezuelan company. It is based on the “amalgamation center” introduced by the Government of Venezuela in the early 1990s. The UNECA Center offers safe gold extraction services and various types of training to artisanal miners. Information about the health and environmental impacts of mining (specifically, the need to avoid mercury vapor inhalation and consumption of mercury contaminated fish) can be disseminated to miners and their families through these centers
