Pesticide residues in apples on the Czech market: Any difference between domestic and imported fruit in contamination pattern?

Popis výsledku v původním jazyce

Apples are one of the most important fruits grown in temperate climatic zones and in the Czech Republic they have a highest share in the total fruit production. During the pre-harvest period and storage, this fruit may be invaded by various pests which may leave residues in the fruit for consumption. Czech producers minimize these residues by, among other things, selecting pesticides that rapidly decompose after application, meaning that the residues are at such low levels that they generally are close, or even below detection limits (LODs) of routine control methods. However, locally-produced high-quality apples compete with imported ones that often contain a rich &apos;cocktail&apos; of residues, the levels of which often exceed the maximum residue limits (MRLs) set by the EU. To obtain up-to-date information about the presence of pesticide residues in apples on the Czech market, we compared pesticide residue pattern found in domestic apples and imported ones. Both LC-MS/MS and GC-MS/MS methods were used to test for pesticide residues in apples of various varieties harvested in several regions of the Czech Republic (40,58% of total amount of the samples) and from other countries (44,93% from Poland, 10% from Italy, 3% from Chile, 1% from Slovakia). 69 apple samples were analysed. Pesticide residues were found in 67 of them (97.10% of tested set). In total, 44 different pesticides were quantified. Maximum Residue Limits were not exceeded in any of the tested samples. While captan, pyraclostrobin, thiacloprid, boscalid and pyrimethanil were most frequently detected in Czech apples, captan, flonicamid, boscalid, fludioxonil and acetamiprid were most frequently detected in foreign ones. Up to 12 different pesticides were determined in a single sample.
