Historic mercury and heavy metal deposition in the Experimental Lakes Area (ELA) reconstructed from lake sediment cores

The Experimental Lakes Area (ELA), in Ontario, Canada, is a sensitive region for heavy metal contamination, such as mercury, in part due to long-range atmospheric deposition from global and regional industrial regions. The region is remote from industrial centres, but is downwind of major pollution sources in North America and Canada, and historically had numerous gold mining sites.
