Flow conditions influence diuron toxicokinetics and toxicodynamics in freshwater biofilms
Influence du courant sur la toxicocinétique et la toxicodynamique du diuron dans les biofilms d'eau douce
Résumé
Biofilms are considered as good bioindicators of contamination by means of their capacity to react quickly to xenobiotics exposure, and their pivotal role in sustaining the aquatic trophic web. The exchanges of dissolved substances between water column and biofilm can be modulated by flow velocity. This study deals with toxicokinetic (transfer mechanisms) and toxicodynamic (effects) modelling of pesticides under two contrasted flow conditions.
