Abstract

In order to manage the environmental risks related to its installations, Hydro- Quebec has done many studies and built a number of computing tools. Most of the software has been developed in a shell which allows easy data input and graphical representation of the results, which can be georeferenced and superimposed on maps. The shell also allows comparison and reuse of results between models. The most recent software is designed for ecological risk assessment for which Hydro-Quebec is developing a framework involving the use of mathematical models. The ultimate aim is to provide a tool which can estimate the fate of pollutants in some compartments of an ecosystem and evaluate the potential effects of chemicals at levels of biological organiz
