GEOLOGICAL CONTROLS CONCERNING MERCURY ACCUMULATIONS IN STREAM AND LAKE SEDIMENTS ACROSS CANADA
  The poster on the left summarizes how total Hg concentrations in stream and lake sediments vary empirically and interpretatively according to geological, topographic, vegetational and atmospheric controls across Canada, based on the open file data of the Geological Survey of Canada (GSC).
ACCUMULATION OF ATMOSPHERIC MERCURY IN FOREST BIOMASS AND SOILS
  This poster decribes the dominant processes by which total Hg is modelled to accumulate in forest biomass and soils over time, in relation to changing forest conditions (mature, old growth, clear-cut, juvenile, etc.) and disturbances (fire, harvesting).
MERCURY VARIATIONS IN STREAM AND LAKE SEDIMENTS ACROSS NOVA SCOTIA, CANADA
  This poster summarizes details concerening total Hg accumulations in lake and stream sediments across Nova Scotia, based on local geological and topographic controls, and within the context of atmospheric Hg depostion.
MERCURY VARIATIONS IN SOIL LAYERS IN RELATION TO TOTAL CARBON, NITROGEN, AND SULPHUR CONTENTS
  This poster provides case-study details about total Hg concentrations in forest soils in relation to Hg controlling retention and release factors. Study area: southwestern New Brunswick, Canada.
