Pesticides used today belong to a wide variety of chemical groups, and the spectrum of physic-chemical properties is further expanded by including their relevant metabolites and degradation products in the analysis. The determination of residues in food, feed, and environmental compartments is needed to support the registration and subsequent enforcement of maximum residue levels as well as for monitoring purposes. Consequently, adequate methods of these compounds are required that allow a selective and sensitive detection at trace levels. At the same time, a trend is developing towards multi-residue methods with high-throughput for efficient analysis. Instrumental advances have allowed for lower limits of quantification, for reduced time of analysis, and for increased separation of matrix and analytes. General issues of residue analysis like contamination and matrix effects and new challenges, such as the inclusion of small and polar/non-polar compounds and/or unusual matrices, will be addressed.
