The present study reports the results of an interlaboratory analysis of selected labile pesticides: trichlorfon, fenamiphos, ethofumesate, phenmedipham, bromofenoxim, chosen among priority compounds, indicated by a European Commission Report as lacking valid analytical procedures. Most of these compounds show stability problems both in solution and during analysis. Each participating laboratory developed methods for the analysis of these compounds and then used the obtained procedure to analyze samples spiked solutions of the five above mentioned pesticides, each in an unknown concentration. Using a different approach, cartridges loaded with samples spiked with the same pesticides were prepared and analyzed for the interlaboratory exercise.
