BfR data for the residue analysis with LC-MS/MS

More than 800 pesticides are used world-wide. In the past, residues of a large number of these pesticides in food and feed could only be analysed using costly methods. The much more effective modern multiresidue-methods utilizeliquid chromatography combined with tandem mass spectrometry (LC-MS/MS) to detect a large number of substances simultaneously in one analysis. Multiple Reaction Monitoring (MRM) is the preferred scan type.

BfR data for ESI-MS/MS detection

For further development of LC-MS/MS techniques and to support official food control, BfRshort forGerman Federal Institute for Risk Assessment provides relevant detection parameters and supporting information for many pesticides. The list of pesticides for which information is available currently contains 639 pesticide active substances and metabolites.

• List of pesticides for which methodological data is available at present.

Furthermore, BfRshort forGerman Federal Institute for Risk Assessment provides the following information for these substances:

• Complete acquisition parameter sets for MRM detection with an API 2000 mass spectrometer (Applied Biosystems) after electrospray ionization (ESI) in positive and negative modeClose dialogmodeModeTo glossary. This collection also contains product ion spectra (often for heavy isotopes such as 37Cl or 34S) and proposals for the structure of the two product ions selected for MRM detection.

  - Complete acquisition parameter sets for positive electrospray part 2 for L-Z.zip
  - Complete acquisition parameter sets for negative electrospray.zip
  - Example from the acquisition parameter sets for API 2000 mass spectrometers
• Mass spectra for product ions at three different collision energies for all pesticides (for confirmation of positive findings).

Drinking water method

Based on these data, the BfRshort forGerman Federal Institute for Risk Assessment developed for 300 pesticides a complete multi residue method for the detection of pesticides in drinking water using an API 4000 mass spectrometer (Applied Biosystems). Many pesticides can be analysed at concentrations of 0.1 µgshort formicrogram/l (drinking water limit value) by this method. Details of the method have been published (Greulich and Alder, 2008). The complete results of the method development are available from "Fast multi residue screening of 300 pesticides in drinking water".
