| Project Summary | |
| The investigation concerns the
partitioning of heavy metals (notably copper and nickel) and various associated elements
among microscopic particles in lake sediments contaminated by emissions from the smelters
at Sudbury, Ontario. The particles, which are being examined by electron microscopy and
analysed by the technique of energy dispersive X-ray microanalysis, comprise a variety of
natural sediment components together with smelter fallout. The information thereby
obtained will provide a basis for drawing inferences about the forms and bioavailability
of the metals and the biogeochemical processes controlling their distribution, speciation,
binding and release, and bioaccumulation.
