A comparative study of the human urinary mycotoxin excretion patterns in Bangladesh, Germany, and Haiti using a rapid and sensitive LC-MS/MS approach
An improved “dilute and shoot” LC-MS/MS multibiomarker approach was used to monitor urinary excretion of 23 mycotoxins and their metabolites in human populations from Asia (Bangladesh), EuropeExpand

Determination of mycotoxin exposure in Germany using an LC-MS/MS multibiomarker approach.
SCOPE In this study, the exposure of a German population (n = 101) to mycotoxins was assessed using an LC-MS/MS urinary multibiomarker approach. Food consumption of the participants was documentedExpand

Thermal degradation of the Fusarium mycotoxin deoxynivalenol.
Deoxynivalenol (DON) is a toxic secondary metabolite produced by molds of the Fusarium genus, which are able to infect cereal crops in the field. Concerning its rate of occurrence and meanExpand

Survey of Alternaria toxin contamination in food from the German market, using a rapid HPLC-MS/MS approach
A HPLC-MS/MS-based method for the quantification of nine mycotoxins produced by fungi of the genus Alternaria in various food matrices was developed. The method relies on a single-step extraction,Expand

Aromatic hydroxylation is a major metabolic pathway of the mycotoxin zearalenone in vitro.
Zearalenone (ZEN) is a common mycotoxin, for which only reductive metabolites have been identified so far. We now report that ZEN is extensively monohydroxylated by microsomes from human liver inExpand

Identification and in vitro cytotoxicity of ochratoxin A degradation products formed during coffee roasting.
The mycotoxin ochratoxin A is degraded by up to 90% during coffee roasting. In order to investigate this degradation, model heating experiments with ochratoxin A were carried out, and the reactionExpand
