Abstract

The tomatoes, commonly known as a tomatoes plant (Solanum lycopersicum L.) belongs to the family, Solanaceae. The cultivation of tomatoes is an important, rapidly developing sector of gardening in Poland. The aim of this study was to detect pesticide residues in the tomatoes cultivated under covers from the region of north-eastern Poland. Ninety two samples were tested using the chromatography technique with mass spectrometry (GC-MS/MS, LC-MS/MS) and spectrophotometrics. The control programme included the of 427 active substances od plant protection products. The results were compared with the maximum residue limits (MRLs). Over half (53.3%) of samples tested contained pesticide residues, and exceeding of MRLs values was stated in one samples. In five samples of tomatoes, fluopicolide, fluopyram and buprofezin residues were found, as an active substances of plant protection product not recommended for protection of this crop. The fungicides were the most frequently detected in the all analysed samples: dithiocarbamates (13.98% of samples), azoxystrobine (11.83%), boscalid (10.75%), chlorothalonil (7.53%) and pyraclostrobin (6.45%). Pomidory (Solanum lycopersicum L.) należą do rodziny psiankowatych (Solanaceae), których uprawa jest ważną i dynamicznie rozwijającą się gałęzią ogrodnictwa w Polsce. Celem pracy była ocena występowania pozostałości środków ochrony roślin (ś.o.r.) w pomidorach pochodzących z regionu północno-wschodniej Polski. Analizie technikami chromatograficznymi z wykorzystaniem spektrometrrii mas (GC-MS/MS, LC-MS/MS) i spektrofotometryczną poddano 92 próbki pomidorów. Program badań obejmował 427 substancji czynnych. Uzyskane wyniki porównywano z najwyższymi dopuszczalnymi poziomami pozostałości (NDP). Ponad połowa (53,3%) przebadanych próbek zawierała pozostałości ś.o.r., natomiast przekroczenia normowanych limitów zanotowano w jednej próbce. W pięciu próbkach pomidorów wykryto fluopikolid, fluopyram i buprofezynę – substancje czynne ś.o.r., niezalecanych w tej uprawie. Najczęściej wykrywaną grupą ś.o.r. były fungicydy, a wśród nich ditiokarbaminiany (13,98% analizowanych próbek pomidorów), azoksystrobina (11,83%), boskalid (10,75%), chlorotalonil (7,53%) i pyraklostrobina (6,45%).
