The role of toxic chemical models in evaluating the impact of contaminants on our water resources / by W.G. Booty and D.C.L. Lam. : En13-5/89-116E-PDF

"Modelling offers a mechanism for optimizing the often competing demands of regulation, environmental protection, and efficacy and cost of control measures. However, the sophistication of current toxic chemical models does not allow the impacts of toxic contaminants on our water resources and human health to be evaluated and predicted with great confidence. There is still a great need for quantitative data in areas such as toxic chemical loads to aquatic systems and biological metabolization, sediment transport processes are also poorly represented in the current toxic chemical models. A means of correlating the results of ecotoxicology analyses with model predicted biotic uptake levels must also be developed. The use of expert system/artificial intelligence frameworks has greatly expanded the flexibility and scope of model applications. Toxic chemical management for large drainage systems is now possible through the use of systems such as the RAISON model (Regional Analysis using Intelligent Systems on a Microcomputer)"--Abstract.
