Title: Solutions from the Field: An Environmental Analytical Approach

Abstract: Traditional monitoring approaches are based
upon discrete sampling methods followed by laboratory analysis.
These approaches do not improve our understanding of the biogeochemical
processes governing trace element species behavior, their transport
and bioavailability, or the relationship between anthropogenic
releases and their long-term impact on aquatic systems. Consequently,
the development of sensitive and selective field-based instrumentation
would be a valuable asset in studying trace element concentrations
and play a role in mapping their biogeochemical behaviour.
This talk describes the development and deployment of field-based
and submersible analytical systems for the monitoring of trace
elements in natural waters. Complimentary laboratory developments
in flow injection-capillary electrophoresis (FI-CE) will also
be discussed.
