The objectives of this project are the further development of strategies making use of the integration of different areas of knowledge on the chemistry and the biological activity of compounds, and their use in the interpretation of biomonitoring data.

These integrated approaches will include:

– the chemical structure and its relevance for the biological activity ((Q)SARs);
– the mechanisms of toxic action for chemicals;
– estimates of the exposure towards these chemicals;
– internal exposure in in vivo situations, as modelled by in silico (PBBK) kinetic models

An essential element in this project is the use of in vitro data on metabolism, in vitro data on the toxicodynamics and the use of these data in physiologically-based kinetic and dynamic modelling. This would enable a quantification of the risk of exposure to compounds.
