“…Tebuconazole is a triazole pesticide that is widely used in agriculture for crop 37 protection due to its broad spectrum of antifungal activities (Shikuku et al, 2014) and 38 included as an active ingredient in wood preservatives (Miyauchi et al, 2005). 39 Concentration levels of tebuconazole (Table S1) of CWs (Langergraber, 2007).…”

“…Interference of triazoles and wood components during liquid chromatography of wood extracts was also reported by Miyauchi et al (2005). They applied clean-up by solid phase extraction on mixed-mode cation exchanger to remove matrix components in methanol extracts from different conifer species (Japanese cedar, Japanese larch, Yeso spruce, Sakhalin fir and Western hemlock) and obtained signals for tebuconazole and cyproconazole that were separated from matrix components.…”

“…Mauruschat et al (2014) applied gas chromatography coupled to field asymmetric ion mobility spectrometry (GC-FAIMS) for fast detection of organic active substances in recovered wood. Miyauchi et al (2005) applied solidphase extraction to remove wood extractives from different conifer species that co-eluted with cyproconazole and tebuconazole. A detailed description of the method development for a GC-MS method to analyze tebuconazole, propiconazole, 3-iodo-propynyl butylcarbamate and permethrin in commercially treated wood was published by Šťávová et al (2011).…”

Suitability of analytical methods to determine tebuconazole, propiconazole and permethrin in aged wood samples

The suitability of common analytical methods for the determination of active substances from wood preservatives in aged wood samples was investigated during an interlaboratory study. Permethrin, propiconazole and tebuconazole were quantified in 1.5 and 8 year-old wood samples by gas chromatography and liquid chromatography. Generally, the applied methods yielded reliable results for these samples. However, wood components can coelute with propiconazole and tebuconazole during liquid chromatography. Optimization of separation might be required if UV detection is applied.

“…According to previous works, a great number of achiral methods for the determination of tebuconazole in various matrixes have been published using liquid chromatographytandem mass spectrometry (LC-MS/MS) [18][19][20], highperformance liquid chromatography (HPLC) with UV detection [21,22], gas chromatography-mass spectrometry (GC-MS) [23][24][25]. The stereoselective degradation of tebuconazole in rabbit was also investigated by a normal-phase HPLC [26].…”

A novel and sensitive method was developed for the determination of tebuconazole enantioselectively using reversed-phase LC-MS/MS. The separation and determination were performed using on an amylose-based chiral stationary phase, a Lux 3u Amylose-2 column (150 mm×2.0 mm), under isocratic conditions at 0.3 mL/min flow rate. A series of chiral stationary phases were investigated and the effect of mobile phase composition on the enantioseparation was discussed. Parameters including the matrix effect, linearity, precision, accuracy and stability were evaluated. Under optimal conditions, the overall mean recoveries for two enantiomers from the soil, tomato, cucumber, pear and apple samples were 79.3-101.1% with 2.8-11.5% intra-day relative standard deviations (RSDs) and 4.1-8.6% inter-day RSDs at 5, 25 and 50 μg/kg levels; the mean enantiomer recoveries from the water samples were 89.6-101.9% with 3.3-10.2% intra-day RSDs and 5.1-7.7% inter-day RSDs at 0.25, 0.5 and 2.5 μg/kg levels. The limits of detection (LODs) for all enantiomers in tomato, cucumber, pear, apple, soil and water were less than 0.6 μg/kg, whereas the limit of quantification (LOQ) did not exceed 2.0 μg/kg. The results indicate that this proposed method is convenient and reliable for the enantioselective determination of tebuconazole enantiomers in foods and environment samples.
