Gas chromatography-tandem mass spectrometry multiresidual method for determination of pesticide residues in honey.

Multirezidualna metoda za določanje ostankov fitofarmacevtskih sredstev v medu s plinsko kromatografijo sklopljeno s tandemsko masno spektrometrijo. (Slovenian)

In our laboratory we introduced and validated a new analytical method for determination of environmental pesticide residues in honey. The extraction was conducted using acetone, petroleum ether and dichlorometane. The determination was conducted using gas chromatography coupled with tandem mass spectrometry. Practical usage of method was analyses of 31 samples of Slovenian honey. 33 active substances (pesticides) were sought. The insecticide cypermethrin was the only active substance found in three samples. The active substances sought were not found in 90.3 % of the samples analysed. The risk assessment showed that no unacceptable risk is expected for consumers. The results were compared with those from the literature. We revealed that honey from Slovenia contained a lower portion of positive samples per active substance sought as in Italy, comparable as in Estonia and Spain, comparable to higher as in Poland and higher as in Egypt.

V našem laboratoriju smo uvedli in validirali novo analizno metodo za določanje ostankov fitofarmacevtskih sredstev iz okolja v medu. Ekstrakcijo smo izvedli z acetonom, petroletrom in diklorometanom, določitev pa s plinsko kromatografijo sklopljeno s tandemsko masno spektrometrijo. Praktična uporaba metode je bila analiza 31 vzorcev slovenskega medu. Določali smo 33 aktivnih spojin (pesticidov). Edina najdena aktivna snov je bil insekticid cipermetrin v treh vzorcih. Iskanih aktivnih snovi nismo določili v 90,3 % analiziranih vzorcev. Ocena tveganja je pokazala, da ni pričakovati nesprejemljivega tveganja za potrošnika. Rezultate smo primerjali z literaturnimi podatki. Odkrili smo, da je slovenski med vseboval manjši delež pozitivnih vzorcev na aktivno snov kot v Italiji, primerljiv kot v Estoniji in Španiji, primerljiv do večji kot na Poljskem in večji kot v Egiptu.
