The definition of pesticide residues (including their metabolites) is essential for the evaluation of compliance to Maximum Residue Levels in food and drink and for surveillance programmes assessing compliance with these standards.

The recent advances in analytics, together with the evolution of regulatory needs and guidance documents have driven the development of monitoring approaches in both environmental and food/feed matrices. In fact, the achievement of such monitoring results is a fundamental step in authorization decisions although inborn challenges have been posed. With this regard, the guidance documents on pre- and post-registration pesticide monitoring pose several critical questions on fitness-for-purposes and demand for robust, effective and sensitive methods overcoming matrix effects and covering both parent compounds and their metabolites. In this framework, either target or untargeted approaches showed some limitation together with inherent advantages, still highlighting the need for future improvement.

This session focuses on novel, effective and comprehensive approaches towards the reliable and accurate monitoring of pesticides and their transformation products into environmental compartments or food/feed commodities.
