Mercury Trade Eludes International Controls

Tracking illicit mercury imports into Indonesia is all but impossible, officials say. But data clearly shows that far more is being carried into the country than is officially recorded, even as the United Nations and other groups try to halt its use globally.
Officials from Indonesia’s trade, environment and energy ministries did not dispute United Nations figures on mercury exports, which show imports hundreds of times as high as the country’s official tally, saying only that the information could not be considered “official” because it had not been generated by the government. But officials acknowledged that mercury smuggling was the most likely explanation, with the material legally leaving foreign countries, then entering Indonesia illegally.
