Evidence from glacier ice: Until it was banned, leaded gasoline dominated the anthropogenic lead emissions in South America

Green Car Congress

Leaded gasoline was a larger emission source of the toxic heavy metal lead than mining in South America, even though the extraction of metals from the region’s mines historically released huge quantities of lead into the environment, according to a study by researchers from the Paul Scherrer Institute PSI and the University of Bern.

Final session on international mercury convention this week expected to culminate in agreement; UNEP Global Mercury Assessment 2013 finds industrial source Hg emissions may be rising

Green Car Congress

Apart from contaminated sites, the mercury pollution detected today is often found in locations very far away from its original source. Increasing industrialization has made Asia the main source region of mercury emissions to air, with East and Southeast Asia accounting for about 40% of the global total, and South Asia for a further 8%.
