Metodi za določanje ostankov fitofarmacevtskih sredstev v vinu s sorpcijsko ekstrakcijo z mešalom ter študija slovenskih vin s trgovskih polic

New analytical methods for the determination of pesticide residues in wine were introduced and validated. Extraction was performed with sorption of the active substances on the stir bar and determination by gas chromatography-mass spectrometry and liquid chromatography-tandem mass spectrometry. The methods were applied in practice. A total of 77 active substances were searched for in 42 wine samples from all 3 wine-growing regions of Slovenia. The fungicides dimethomorph, fludioxonil and pyraclostrobin were found in 78.6% of all analysed samples. The risk assessment concluded that the analysed wine samples do not pose an unacceptable risk to consumers. The results were compared with previous studies.Uvedli in validirali smo novi analizni metodi za določanje ostankov fitofarmacevtskih sredstev v vinu. Ekstrakcijo smo izvedli s sorpcijo na vrteče se magnetne paličice in določitev s plinsko kromatografijo, sklopljeno z masno spektrometrijo, in s tekočinsko kromatografijo, sklopljeno s tandemsko masno spektrometrijo. Metodi smo uporabili v praksi. V 42 vzorcih vina, zbranih iz vseh treh vinorodnih območij Slovenije, smo določali skupno 77 aktivnih spojin. Fungicide dimetomorf, fludioksonil in piraklostrobin smo določili v 78,6 % vseh analiziranih vzorcev. Z oceno tveganja smo ugotovili, da analizirani vzorci vina ne predstavljajo nesprejemljivega tveganja za potrošnika. Rezultate smo primerjali s predhodnimi raziskavami
