“…[6][7][8][9] Besides, there is not any maximum residue limit for the tetraconazole in strawberry in China. [12][13][14][15][16] For instance, the bioactivity of (−)-Rtebuconazole is higher than that of (+)-S-tebuconazole, 17 which exhibited high toxicity to aquatic non-target organisms (Scenedesmus obliquus, Daphnia magna, and Danio rerio). The oral toxicity study demonstrated that tetraconazole was slightly toxic to mammals and moderately toxic to birds.…”

The fate of tetraconazole enantiomers in strawberries during wine-making process was studied. The residues were determined by ultra-performance convergence chromatography tandem triple quadrupole mass spectrometry after each process steps. Results indicated that there was significant enantioselective dissipation of tetraconazole enantiomers during the fermentation process. And (-)-tetraconazole degraded faster than (+)-tetraconazole. The half-lives of (-)-tetraconazole and (+)-tetraconazole were 3.12, 3.76 days with washing procedure and 3.18, 4.05 days without washing procedure. The processing factors of strawberry wine samples after each step were generally less than 1. In particular, the processing factors of the fermentation process were the lowest. The results could help facilitate more accurate risk assessments of tetraconazole during wine-making process.

In this work, a carbon nanosphere decorated by Fe3O4 nanoparticles was prepared, characterized and used as the magnetic adsorbent. Eight commonly used chiral triazole fungicides, including penconazole, uniconazole, paclobutrazol, triazolone, tebuconazole, hexaconazole, triticonazole and epoxiconazole were extracted from two environmental water samples (river water and lake water) by magnetic solid‐phase extraction, followed by the enantiomeric analysis on a Chiralpark IC column coupled with a triple quadrupole mass spectrometry to evaluate their possible stereoselective degradation occurring in the water samples. The possible factors affecting the extraction performance, such as amount of used adsorbents, pH and ionic strength of water solution, types and volumes of desorption solvents were systematically investigated. Under the optimum conditions, extraction yields of eight triazole fungicides were above 80% and the concentration factors were as high as 1000. Method detection and quantification limits for the enantiomers of eight triazole fungicides were in the range of 0.56–6.95 ng/L. Satisfactory accuracy (relative recovery 77.8–93.5%), good intraday precision (RSD 4.3–9.8%) and interday precision (RSD 3.1–7.9%) were also obtained. The developed method provided the simplicity of operation, rapidity and high enrichment factor, which can be used to monitor and evaluate the behavior of the individual enantiomer of chiral triazole fungicides.

The LODs reported by Li were less than 0.6 μg/kg, whereas the limit of LOQ did not exceed 2.0 μg/kg.…”

A fast and an efficient ultrasound-assisted extraction technique using a lower density extraction solvent than water was developed for the trace-level determination of tebuconazole in garlic, soil and water samples followed by capillary gas chromatography combined with nitrogen-phosphorous selective detector (GC-NPD). In this approach, ultrasound radiation was applied to accelerate the emulsification of the ethyl acetate in aqueous samples to enhance the extraction efficiency of tebuconazole without requiring extra partitioning or cleaning, and the use of capillary GC-NPD was a more sensitive detection technique for organonitrogen pesticides. The experimental results indicate an excellent linear relationship between peak area and concentration obtained in the range 1-50 μg/kg or μg/L. The limit of detection (S/N, 3 ± 0.5) and limit of quantification (S/N, 7.5 ± 2.5) were obtained in the range 0.2-3 and 1-10 μg/kg or μg/L. Good spiked recoveries were achieved from ranges 95.55-101.26%, 96.28-99.33% and 95.04-105.15% in garlic, Nanivaliyal soil and Par River water, respectively, at levels 5 and 20 μg/kg or μg/L, and the method precision (% RSD) was ≤5%. Our results demonstrate that the proposed technique is a viable alternative for the determination of tebuconazole in complex samples.
