Abstract

In the present study, 327 pesticide residues in 666 brined vine leaves collected from the Aegean Region in Turkey during 2014-2016 were quantitatively analyzed by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) after a multiresidue extraction procedure, named the QuEChERS method. The obtained results were evaluated according to maximum residue limits (MRLs) for each pesticides by the Turkish Food Codex (TFC) and European Commission (EU) MRLs. 173 of the samples contained detectable residues at, above, or below TFC MRLs, and 124 of the samples contained pesticide residues above TFC MRLs. Azoxystrobin, boscalid, cypermethrin, difenoconazole, imidacloprid, metalaxyl, metrafenone, myclobutanyl, penconazole, pyraclostrobin, pyrimethanil and triadimenol were mostly found. Azoxystrobin was the residue that most exceeded the TFC MRLs, and metalaxyl was the most frequently found residue in brined vine leaves.
