The applicability of Biotic Ligand and Critical Residue Approaches to Canadian Shield conditions
One of the main focal points of this research project is to test whether the currently developed BLMs are predictive of effects for sensitive native species in the relatively soft and slightly acidic waters of the Canadian shield. Part of this will be to make comparisons of the sensitivity of native fish relative to standard fish species (e.g. rainbow trout and fathead minnow). The research will also test the applicability of geochemical speciation models for predicting metal-NOM interactions. In terms of chronic toxicity it is expected that data will contribute towards understanding the CBR approach and its relevance in the context of native species in Shield waters. Whether in the context of site specific assessments, ecoregional assessments, setting of water quality guidelines and/or criteria, or setting of industrial discharge objectives, the results will contribute directly to ecological risk assessment.
