Mathematical modeling for predicting the fate of contaminants in freshwater ecosystems [electronic resource] : a review / Efraim Halfon. Burlington, Ont. : National Water Research Institute, Canada Centre for Inland Waters, [1986]. 31, [10] p. : ill. NWRI contribution ; # 86-23 Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "The knowledge of toxic contaminants fate in the environment is important given the large number of chemicals (about 60,000) presently in use. Mathematical models have been used to predict contaminants fate but the incomplete knowledge of the relation between the chemical structure and environmental behaviour makes predictions uncertain. Here, basic principles of fate models are reviewed with a discussion of the latest topics of interest in ecological modelling. These topics include a) expert systems to catalog information about new and existing contaminants and pesticides and to improve the registration process; and b) theory of model development to minimise the uncertainty in predictions and to identify important processes, whose detailed knowledge would improve our confidence in fate models"--Exec. summary, p. 2. gccst Water pollution gccst Modelling Canada.
