Screening of pesticide in apple ciders by liquid chromatography-high resolution mass spectrometry

Popis výsledku v původním jazyce

The present study is focused on separation and detection of pesticides residues in apple ciders. The main target of this experiment was not only to determine the concentrations of these residues carrying over from apple peels into the beverages but also to evaluate their potential risk to consumer&apos;s health. For the extraction the QuEChERS method was used in combination with additional column SPE sample clean-up to achieve the lowest detection limit possible due to low concentrations of pesticide residues. The samples were analysed using a high-resolution accurate-mass (HPLC-HR/AM) instrument and this applied method assured the quantification of pesticide residues in the ciders possible at 0.2 ppb level for most of fifty target pesticides. Additionally, non-target screening mode enabled to verify presence of over 300 pesticides using comprehensive library including retention times, empirical formulas, and verified fragments.
