International audience; A sensitive LC-MS/MS method for the simultaneous determination of type A, B, and D trichothecenes in cereals is presented. The limits of detection ranged between 0.1 µg kg-1 and 0.7 µg kg-1 for all analytes. The method was a

Results from the Bavarian Health and Food Safety Authority on contamination of cereals and cereal products from the Bavarian market with the mycotoxins deoxynivalenol (DON), zearalenone (ZEA), and ochratoxin A (OTA) and of maize meal and semolina wit

Ochratoxin A, one of the most toxic mycotoxins, can be metabolized nearly completely by suspension cultures of various plant cells. The transformation products identified in this study were almost the same in the cell-suspension cultures of maize, ca

Es wird ein Uberblick uber die Moglichkeiten des Schadstoffmetabolismus in Pflanzen gegeben. Neben der Umwandlung in losliche Metaboliten und der Festlegung in die pflanzliche Matrix ist die Konjugation von Schadstoffen mit zelleigenen Substanzen vom

An LC-MS method was developed for the analysis of zearalenone-4-beta-D-glucopyranoside and zearalenone in wheat (Triticum aestivum). The limit of determination for zearalenone-4-beta-D-glucopyranoside and zearalenone was 10 microg/kg. The recovery ra

Zearalenone-4-β- d -glucopyranoside was synthesized via a chemical reaction between zearalenone and 2,3,4,6-tetra-O-acetyl-α- d -glucopyranosylbromide, followed by deacetylation. By this way the exact molecular structure of the glucose conjugate, f

Among cereals, oats are known to be very frequently contaminated with type A trichothecenes and so they can play a major role in the exposition of the consumer to these mycotoxins. Seventy representative oat samples of both conventional and organic p

To obtain information on differences between the metabolic pathways of the herbicide glufosinate (trade names: BASTA, LIBERTY) in non-transgenic, glufosinate-sensitive plants and in transgenic, glufosinate-resistant plants, the metabolism of 14C-labe

The aim of the present study was to determine whether post-emergence application of glufosinate to transgenic crops could lead to an increase in residues or to the formation of new, hitherto unknown metabolites. Transgenic oilseed rape and maize plan
