Working group Toxinology

Toxinology is the area of science that deals with natural toxins (biotoxins), including their chemistry, mode of action, ecological roles and interaction with life forms. Our working group studies in particular toxic fungal metabolites (mycotoxins), their metabolisation in plants, toxicokinetics and detoxification.

Central to our work is the development and application of liquid chromatography – mass spectrometry (LC-MS) based methods to determine biomarkers. Biomarkers are objective, quantifiable characteristics of biological processes, medical states or exposure, which can be measured accurately and reproducibly.

Biomarkers allow to e.g.

  • assess the exposure to and uptake of compounds of interest by a given individual
  • conduct epidemiological studies to correlate toxin intake with potentially associated diseases
  • study the metabolism of compounds as part of toxicokinetic studies
  • assess the toxicity of metabolites (e.g. modified mycotoxins)
  • investigate the efficacy of detoxifiers (e.g. feed additives)
  • determine fluctuations in individual detoxification of certain compounds
  • describe the state of health of a given individual for a specific illness

We use targeted and untargeted LC-MS(/MS) approaches to detect, characterize and quantify known and novel metabolites. Toxinology is an incredibly interdisciplinary field of science with strong links to analytical chemistry, biochemistry, bioinformatics, medicine, microbiology, molecular biology, pharmacy, toxicology and veterinary medicine. In our case additional links are established to mycology and various plant sciences at the BOKU campus Tulln and abroad.
