Rates of trace metal release due to mineral weathering (Sources)

Objectives being Investigated
The determination of rates of release of trace metals resulting from the breakdown of primary minerals, which naturally contain trace metals, in soils. This process is a natural source of trace metals to the surface environment that needs to be quantified so its magnitude can be compared with anthropogenic releases.

Study/Sampling Design
Study sites (3) were established along each of two transects following decreasing gradients of soil metal concentrations near Sudbury, Ontario, and Rouyn-Noranda, Quebec. At each site soil samples were collected from soil profiles so that the trace metal bearing minerals could be identified. These two transects are also the subject of studies under projects led by Hale (B1) and Courchesne (B5).
