Objective(s): Currently, there is no information about the bioavailability and toxicity of metals in the Slave River delta. The goal of this research is to examine metal cycling pathways in the delta and to assess the role of aquatic vegetation for metal accumulation in a variety of depositional environments. The objectives of the research are; 1) to quantify the amount and type of metals in pore water, sediment and plants; and 2) to determine the toxicity of sediment-associated metals. Results of the study will be used to develop a metal partitioning model and interpreted in the context of current legislative and policy frameworks developed to manage northern environments of high ecological significance.
