Currently research is carried out in the following fields :

  • the development of methods for the determination of pesticides in various matrices (crops, soil, water, air, formulations)
  • the presence of pesticide residues in the total diet
  • the influence of conservation methods and culinary treatments on the fate of residue levels in food
  • the influence of interfering factors on the fate of pesticides (degradation in field and lab experiments, behaviour in soil and plants, metabolic fate)
  • the influence of formulation and application aspects on the efficacy of pesticide treatments
  • the physicochemical properties of spray solutions
  • the effect of additives and adjuvants (surfactants) on spray performance and contact formation
  • the exposure assessment during and after pesticide application in greenhouses and field-application
  • the evaluation of the exposure risks of pesticide applications
  • the development of indicators and models for evaluation of the environmental impact of pesticides
  • the study of drift during and after pesticide application
  • the detection of pesticides in rain water
  • the modelling of the fate and behaviour of pesticides in the food chain and the environment
  • the impact of climate change on pesticide use


Current research projects

  • Michael Houbraken carries out research on the effect of surfactans on the volatility of pesticides next to his tasks as an assistant.
  • Shirley Mahabali evaluates agricultural practices in Suriname by means of interviews. She investigates the use of wetlands for agricultural wastewater treatment to decrease water pollution.

Previous research projects

  • Veg-i-Trade, a project funded by the seventh Framework programme for research of the European Commission. The project seeks to assess the impact of anticipated climate change and globalisation on the safety issues concerning fresh produce and derived food products. Research concerns the economic structure of the fresh produce chain, and control measures to minimise microbiological and chemical risks will be developed (
  • BROWSE, a project funded by the seventh framework for research of the European Commission. The Laboratory of Crop Protection chemistry investigated the exposure of workers during re-entrance activities such as harvest (
  • Jean Pierre Ouattara studied the efficiency of musquito nets. He determined the effect of washing and UV-light on the amount of insectices in and on the nets. Additionally he investigated possible human health risks when touching the nets.
  • In collaboration with the ILVO, Bert Beck studied the use of entomopathogenic nematodes for insect pest control. His research was part of a IWT agriculture research project that investigates formulation and application techniques.
