Objectivies and Approach

This project will study the development of expert systems (ES) and their application to environmental toxicology. This will involve:

European links: A related EU project, EV5V-CT92-0061, dealing with experimental studies on degradation of pesticides, will be considered.

Progress and Results

During the first year of the project, an integrated architecture of a system with rules to reason on the presence of possible toxic substructures and ANN to reason on the whole molecule has been defined. The fitotoxity of three classses of compounds could be computed. A set of rules recognises substructures and computes the toxicity. This set of rules has been extended by additional rules that deal with the phototransformations of more than hundred compounds. Work is in progress concerning the assessment of a framework for all toxicity data found in different data sets.

Information Dissemination Activities and/or Exploitation

Results are disseminated through published papers, by participation in international and national conferences and through partners who have connections with public health authorities. The results will integrated into a commercial system.
