Mercury and New Math

One, mercury, is a major component of small scale gold mining in Indonesia and the other, New Math, is used to account for the amount of mercury imported into the country.

“We put 15 kilograms of gold ore and water into each ball, and we use 100 grams of mercury per ball,” or 3.5 ounces for 33 pounds of ore, said David, who runs the family’s workshop. Workers then purify the nuggets using an open flame, burning off the mercury in sites among residential areas throughout the village.

Yuyun Ismawati, an environmental campaigner based in Britain, says the scope of the problem is evident in the amount of mercury being exported from around the world to Indonesia, her home country. Most of it, she says, is brought in illegally.

According to the Indonesian Ministry of Trade, the country imported slightly less than one metric ton of mercury in 2012 through two local companies, primarily for commercial manufacturing, including the production of light bulbs and batteries, and for use in hospital equipment. According to United Nations trade statistics, however, 368 metric tons of mercury, about 810,000 pounds, were legally exported to Indonesia in 2012 from countries that included Singapore, the United States, Japan and Thailand.

The yawning gap between what Indonesia officially reported as receiving and what was actually exported to it is not an anomaly. In 2011, the country officially imported 7.8 metric tons of mercury, while the United Nations reported that 286 metric tons was exported to Indonesia. The same disparity is evident for numerous other recent years.

In fact, the only data that added up for Ms. Yuyun, 49, a graduate school alumna of Oxford, was not about mercury but global gold prices, which nearly doubled from an average of $872 an ounce in 2008 to $1,669 in 2012. Gold ended 2013 at just over $1,200 an ounce.

To Ms. Yuyun, the conclusion was obvious: Hundreds of tons of mercury had been smuggled into Indonesia for illegal, small-scale miners in a modern gold rush that analysts and activists say is causing major environmental and health crises.

“It’s quick cash,” she said. “You dig, you get money — and you get poisoned.”

The large scale industrial mines can afford mercury free methods but the lure of quick riches draws in many who can only afford the mercury process. Will they make enough to pay for their future afflictions?
