Multiresidual gas chromatography-tandem mass spectrometry method for determination of plant protection product residues in fruit

A multiresidual method for the determination of 29 active substances was developed and validated. Acetone, petroleum ether and dichloromethane were used for extraction, and a gas chromatograph coupled with a tandem mass spectrometer was used for determination. A survey was conducted to test the method in practice. Twenty-two samples of apples, apricots, blueberries, grapes, nectarines, oranges, pears, raspberries and strawberries were analysed. The active substances found in the samples were fungicides: boscalid, cyprodinil, fludioxonil, fluopyram and pyrimethanil. Finally, a consumer risk assessment was conducted.
