Mercuring Poisoning Among Indonesian Mining Communities-slide show

Where there is small-scale gold mining, there is mercury—and often mercury contamination. The Republic of Indonesia, the world's fourth most populous country, is home to some of the globe's richest gold deposits—and some of the world's worst mercury contamination. Over the last two decades, as gold production has exploded, more than a million small-scale gold miners have joined the large multi-national corporations working in Indonesia. These small operators use mercury to extract gold from ore, often working in their homes and backyards where they expose themselves, their families, and their unborn children to extremely high concentrations of the toxic heavy metal.
