Natural co-occurrence of mycotoxins in wheat grains from Italy and Syria
2014
This article describes the application of an analytical method for the detection of 25 mycotoxins in wheat grain based on simultaneous extraction using matrix solid-phase dispersion (MSPD) followed by liquid chromatography coupled to tandem mass spectrometry, a hybrid triple quadrupole-linear ion trap mass spectrometer (QTrapÒ). Information Dependent Acquisition (IDA), an extra confirmation tool for samples that contain the target mycotoxins, was used. The analysis of 40 Syrian and 46 Italian wheat grain sam- ples interestingly showed that Syrian samples were mainly contaminated with ochratoxin A and aflatox- ins, whereas Italian samples with deoxynivalenol and 15-acetyldeoxynivalenol.

Simultaneous determination of Fusarium mycotoxins in wheat grain from Morocco by liquid chromatography coupled to triple quadrupole mass spectrometry
2014
Abstract In the present study, eighteen (18) mycotoxin produced by the genus Fusarium (fumonisins (FB1, FB2 and FB3), type-B trichothecenes (NIV, DON, FUS-X, 3Ac-DON and 15Ac-DON), type-A trichothecenes (NEO, DAS, T2 and HT2), zearalenone (ZEA), beauvericin (BEA), and enniatins (ENA, ENA1, ENB and ENB1)) were monitored in different samples of wheat grain commercialized in Morocco. A liquid chromatography coupled to triple quadrupole mass spectrometry method previous matrix solid phase dispersion extraction was used for sample analysis. A total of eighty (80) samples of durum wheat were collected in different local markets from several areas in Morocco. Analytical results showed that 54 out …
Long-term tillage and crop sequence effects on wheat grain yield and quality.
2013
Much research around the world has compared the performance of cereals grown under conventional and conservation tillage systems; however, relatively few long-term experiments have been conducted in Mediterranean areas, and little attention has been given to interactions among tillage techniques and other system components across space and time. In this study, we investigated the effects of the long-term (18-yr) use of three tillage techniques (conventional tillage, CT; reduced tillage, RT; and no-till, NT) on wheat (Triticum durum Desf.) grain yield and quality within three crop sequences: continuous wheat, faba bean (Vicia faba L.)–wheat, and berseem clover (Trifolium alexandrinum L.)–whe…
