Analysis of pesticide residues was performed by Ultra Performance Liquid Chromatography (UPLC) with Photodiode Array Detector (PDA). Mushroom samples were prepared by acetonitrile extraction. Chromatographic separation was achieved using a BEH C18 analytical column (2.1 mm 150 mm), 1.7 μm particle size at flow rate of 0.25 ml/min. Validation studies were carried out on mushroom. In the linear range (0.01 and 0.1 mg/kg) of each pesticide, the correlation coefficient was R2 > 0.99. The relative standard deviation was below 17.1% for all pesticides. The recovery and repeatability of results are in compliance with SANCO/2009 criteria (i.e. average recoveries were in the range 70–120% with RSDs < 20%) for all pesticides The developed method was successfully applied for determination of pesticide residues in mushroom, apple and black currant.
