| Sumario: | Parent tetracyclines and their transformation products can be present in vegetables growth in soils amended with manure, treated sewage sludge, or irrigated with reclaimed urban wastewater. The presence of some tetracycline antibiotics and transformation products is already regulated in foodstuffs of animal origin but not yet in vegetables. In this paper, an analytical method is proposed for the determination of seven parent tetracycline antibiotics and six transformation products. Selected transformation products correspond to epimers and dehydration products, which have been reported to be the most toxic ones. The proposed method is based on miniaturized matrix solid-phase dispersion (μ-MSPD) method combined with online solid-phase extraction–liquid chromatography–tandem mass spectrometry (online SPE–LC–MS/MS) determination. The method has been validated in radish edible parts (leaves and bulb), to be used for food monitoring, and in roots, to be used in pollutant plant uptake and translocation studies. Proposed method provides MQLs lower than 5ngg⁻¹ dw, accuracy in the range 85–100%, and RSD% lower than 5.5%, for most of the compounds and matrices. Application of the method to radish samples revealed the presence of transformation products of tetracycline antibiotics even in samples where their respective parent compound was not detected. Greenness assessment, using ComplexGAPI and AGREEprep Green Analytical Chemistry metrics, revealed the highest greenness degree of the proposed method in comparison to other methods reported in literature for determination of tetracycline antibiotics in vegetables. |
