"GENEVA -- Mercury pollution in the top layer of the world's oceans has doubled in the past century, part of a man-made problem that will require international cooperation to fix, the U.N.'s environment agency said Thursday."

"The report by the U.N. Environment Program showed for the first time that hundreds of tons of mercury have leaked from the soil into rivers and lakes around the world.

As a result of rising emissions, communities in developing countries face increasing health and environmental risks linked to exposure to mercury, the U.N. agency says."
