Abstract

There are hundreds of abandoned and active metal mine tailings cells, containing a variety of toxic metal(loid)s, across Canada’s boreal forest. Many of these tailings are either being naturally or actively revegetated, but how boreal plants interact with substrate metal(loid)s is poorly understood. By understanding how tailings chemistry affects plant growth, and if plants sequester these toxic elements in their tissues, ecologically sound restoration of these sites can be improved. I am studying boreal plants growing in gold tailings using traditional lab techniques and spectroscopic and imaging methods from the Canadian Light Source (CLS) synchrotron.
